Let's peel back the friction material on different aftermarket brake pads!
We'll examine five different brake pads to see how they differ internally.
Sponsored By NRS Brakes - www.nrsbrakes.com
There are four fundamental elements of brake pad design that play a critical role in brake functionality and safety. Rust protection for the backing plate, how you attach the friction material to the backing plate, the flatness of the backing plate, and the tolerances of the abutment areas, ensuring the pads slide smoothly within the caliper.
In this video, we’re focusing on just one aspect, the attachment of the friction material to the backing plate. We'll inspect five different brake pads: one original equipment, one from NRS Brakes, and three other aftermarket companies. You'll very clearly see the original equipment pads use mechanical attachment, as does NRS, yet two of the aftermarket companies do not.
Mechanical attachment uses hooks to ensure a very secure bond between the friction material and the backing plate, which is especially important for applications that see high heat. Heat can break down adhesives, whereas the mechanical attachment will remain strong. Yes, you can buy brake pads designed for the exact same vehicle, without ever knowing that they don’t feature the technology that the original equipment pads specify.

I worked in aftermarket parts cataloging for about 8 years. The FMSI book was a basically a bible. Data changes by the supplier is the biggest achilles heel, resulting in "these pads don't fit my vehicle" complaints. I still learned quite a bit from this one! very interesting.

**Lots of discussion in the comments, let's address the major points!** 1. To be clear, as stated in the video, this is about applications where the OE specifies mechanical attachment (heavy duty trucking, towing, some track cars, etc). You can see an image of these types of vehicles at 12:40 in the video. *If the OE does not specify it needs mechanical attachment, I'm not here to say it does!* I think OEs are smart and know what they're doing. The tech (mechanical and adhesives) has been around long enough for them to decide, based on the application. 2. How often does failure occur (for the "I've never seen a brake pad fall off" queries)? Safety is a probability game. Even if the chances of failure are very small, when you're talking tens of millions of vehicles, getting different quality replacement pads, then it becomes a reality. NRS gave a presentation at SAE where they pulled numerous examples from NHTSA where pad separation was failure point and cause of the accident. Unfortunately, it does happen. 3. 8 Day Oven Test (addressing "my car doesn't drive downhill for 8 days"). This is providing a method for understanding adhesive failure over a long period of time. It doesn't happen all at once (you could get 50,000 miles, or more, on the pads). In high heat applications, that heat can break down the adhesives, as the data showed. *Edit:* Worth mentioning, as the adhesive breaks down on the backing plate, this makes it easier for rust to creep in behind the friction material. This leads to rust jacking (as shown in the video), which eventually can fully separate the friction material from the pad. 4. What's the point? The point is for these specific OE applications, there are aftermarket brands saying they're essentially OE replacement pads, yet they're not playing by the same criteria as the OE. There should be an easy way for consumers to know. I found that fascinating, so when NRS approached me about a video on it, I was in. 5. Lastly, I appreciate all the pressure in the comments; it improves things long term! I do think I could have explained certain aspect better, after reading through here. Also, I think it could be a really interesting test to put the pads from the video through the 8 day 550ºF test. For what it's worth, I take sponsorship very seriously, and turn down probably 95% (if not more) of the offers that come my way. I thought this was a really interesting subject to learn about, and I have worked with NRS in the past, so I was happy to work together on this video. What would make things better for next time? I'm open to your feedback, thanks!

I work in stress testing and reliability, of semi-conductor parts but a lot of the methodology is the similar. On of the things that hard to get through to new people is the idea of accelerated life spans, ie. how can we show that a part will fail in five years vs 3, when we only test them for a few days/weeks? It seems the idea of cumulative stress is pretty unintuitive to people. "If I don't push it hard enough to break it immediately, it will never break."

I know the reasons behind the choice (I think) but I really don't like the hiding of brand names behind "a leading supplier" or such terms. These companies but products up for sale that anyone can buy, just name them! It is fairly easy to find out what products are from what companies if you do some research but it shouldn't be this way in my opinion. You say " they're not playing by the same criteria as the OE. There should be an easy way for consumers to know.", so tell us the names so we know! On a positive note great job breaking down the oven test chart in a concise way. Always look forward to your videos, hope you are doing well.

@andypolo7928 8 месяцев назад
Generally I like your videos, but this one is just a promotional video for NRS. The test shown has nothing to do with reality and only pads with a machanical retention can pass it. A common OE customer requirement is to shear the pads after a performance test specified by the OE customer. It is very rare for pads to see 550°C in the glue area as the temperature continues to decrease from the friction surface to the backign plate. This could happen with long track use, but at these high temperatures the coefficient of friction also decreases significantly and the driver would notice that the brake is overheating. There are many OE applications that only use glued pads and it works just fine.

Here in the New England rust/salt belt, besides rust jacking on the pads, you also have to worry about rust/salt on the entire caliper and pins. Frozen calipers can result in very uneven wear on any pad which can break/chip/overheat them. So even if you have a perfect pad with mechanical attachment, perfect rust-free backing plate, etc, you still have to worry about the rest of the components failing due to rust/salt.

I usually take the 30 minutes to just take the brakes apart and grease them when I rotate wheels or swap winter wheels. My last 'daily' car the front calipers are original but rears failed after 15 years because I didn't pay as much attention and they didn't move as much (2-3 sets of fronts to one set of rear pads). I have a feeling rust jacking is what caused 3 sets of Hawk pads to separate. They would barley last 2years, 15k miles.

Over my 20 plus years in the automotive repair industry I’ve seen a few pad separations. Personally I’m all in for mechanical connections, however I’ve seen pad separations on mechanically connected and adhesive bonded pads. While I’m just one tech without any type of scientific method or control, in my experience it doesn’t seem like any one type of connection is more separation proof then the other in real world. Now I’m sure the vehicles I mainly work in and my location in the country have a big influence on that. So it’s entirely likely my experience would be completely different if I was working on a different brand or in a different climate. However I will state that I absolutely have seen galvanized and mechanically connected pads be separated by rust jacking. Galvanized coatings don’t stand a chance against that horrible horrible brine they use on the roads in winter. Just my worthless 2 cents.
@stans5270
@stans5270 7 месяцев назад
Separation of the friction material from the backing plate was a major concern when the industry started to move away from riveted brake shoes and pads. That was rectified in the first 5 years. I guess with today's increase in weight limits and towing capacities, this might also again become a problem for 0.001% of people who drive trucks.

I believe that the zinc plating that NRS is using might help some, but given it is just plating, I believe it will have its limits as well.

Especially since you have mentioned that you have seen both types fail.

The brakes that I recently changed out on my 09 were beginning to separate from the backing plate, which used a mechanical attachment. Unfortunately, I would have to agree that rust jacking will get the best of any brake pad if left on for enough time.

Everyone wants to blame the manufacturer but if twenty year old cars are rust free for 18 of those years and then two winters after the brine goes into use, it’s falling apart, I don’t think it’s the manufacturer’s fault.

My Volvo C30 had Brembo "oe replacement" pads from the previous owner. When I changed them, one of the right front pads had split in two with the friction material completely separated from the backing plate, no mechanical attachment, just adhesive. And I was traveling to the Nürburgring a few days after, so I'm super glad I upgraded my brakes before I went. Though the previous owner had installed the wrong size front discs, so that is probably the reason why the pad was destroyed, I don't think it would have happened otherwise. Now I have Brembo's XTRA line of pads on the car, and they're working great, though I could not find any information on how the friction material is mounted.

I installed a PowerStop front brake kit to include cross drilled rotors and carbon ceramic pads on my 2001 Subaru Outback LL Bean [H6] last year, and this spring I did the rears with their kit for the rear brakes. I don't think the car stops any better, but the carbon ceramic pads seem to produce NO dust and the kit was very well done, with complete instructions and most importantly.... Instructions on how to BED THE BRAKES! If you just put rotors and pads on your car and go and drive it, a year later your pedal will be pulsing. You have to "bed" the pads and rotors, or they WILL warp~ Most cheesy repair shops won't do this properly. Or at all! Great video!

It kinda depends on how you value your time. I slung hundreds of those pads in a former life as a counter tech. Very, very few people actually made us replace those lifetime warranty pads...mostly it was lots of used car lot jockeys that bought the cheapest Valucraft pads. The cars only had 30 day warranties, so as long as those cheap pads lasted 30 days...that was all they cared about. The most interesting issue we had with the lifetime warranty pads were friction material disintegration on riveted pads...the material would crumble and bam...rivets into the rotors, metal to metal. Ruined the rotors. Naturally only the pads were covered, the rotors became junk. The problem there was that whoever was making the pads, tried making the material last for such a long time they compromised the temperature tolerating ability of the material...it burned off the binder and then the pad began to crumble. Lots of unhappy customers. This was back in the mid eighties. Now if it's the family truckster that I depend on to get all of us safely from point A to point B...you better believe I'm putting on the best stuff I can find. The best stuff isn't necessarily the most expensive.

Does this test actually simulate real world usage though? putting brake pads in an oven for 24+ hours? Track use maybe, but even track use will see a pad swap before 24 hours of driving.
@berto1014
@berto1014 8 месяцев назад
It's an accelerated test. Of course it doesn't simulate real world usage. This is to accelerate the aging/heat degradation of the glue and friction material to see what would fail first in a long-term scenario. Brakes are typically used for years, and the damage accumulates over time. These are the types of failures you would see closer to EOL of the brake pad, or in very extreme braking situations potentially. Accelerated tests are used quite frequently in many industries, despite not simulating real world usage. Simulating real world usage would take much longer to identify primary failure points. For example, in pavements, we use accelerated aging in an oven to simulate long-term real world aging to determine which mixtures are more resistant to cracking than others.

Baking brakes at 550 for 5x24 straight is a testing methodology designed exactly to kill those glues. Hard to think of a more obviously biased 'test'. No doubt mechanical is better, however with the 300 million vehicles on the roads, NHTA could only come up with a handful? Pretty sure if this were anywhere near pervasive, they'd have already addressed this as a Life/Safety issue and mandated mechanical attachement as a minimum. Unless I missed it, odd that they didn't actually show any of the testing where they sheared off the pads, maybe worried that people would call BS?

Mechanic of 20yrs here, I've seen a lot of separated pads due to corrosion. I've seen cracked pads from heat and heat cracked rotors. Most commonly separated friction materials I see are drum shoes oddly enough, often parking brake shoes due to rust. I haven't yet seen a pad cooked off a backing plate, not to say it can't happen and doesn't happen but my experience is that rust will get ya before anything else, often the rest of the brakes are seized up pretty hard at that point as well. Sticking slides and pads bound in brackets are very common issues with brakes.

Another point to consider, rusting of the backing plate / pad that contains steel fibers. In road salt areas, I've seen pads de laminate as well as the friction material crumble.

Unfortunately the soil in our vehicle park isn't well drained and they frequently have to be parked in puddles for days at a time. Our specific problems are 1) Sliders seizing and wearing out the pad on the piston-side of caliper. 2) Rusting onto the rotor/drum which either rips all or part of the pad/lining apart. 3)Dragging overheating from stuck sliders and or pistons. #3 above is particularly awful because it always kills the grease seal and when grease gets onto brakes you just have to start all over with brand new stuff.

If an OE or major company chooses to select a pad that only uses adhesives, I have no problem with that. A company that's spent decades building their name won't risk large scale lawsuits and government fines if they thought their pads weren't safe. The sheer forces on brake pad material is hardly my primary concern seeing as I've never seen or heard of pad material ever failing on any brake pad. This sounds like a company I've never heard of trying to stir up some business. There's three types of brake pad buyers: the "just goes to the dealership", the "whatever's the cheapest", and the "picks a specific pad for their specific purpose DIYer". The first two aren't watching this video, and the third group has already researched their specific brand for a specific reason. I don't see this oddly specific complaint changing many minds.

Im not sure if i agree with their testing method, where they apply a shearing force directly onto the side of the friction material. In real world applications, wouldnt the pads themselves be smushed together, both by the caliper, and some (minor) bending moments created by the disc pulling the material from the top, rather than pushing from the side? I can see the point they are trying to make, that one IS probably theoretically better than the other. It does indeed handle more load, but does it matter in a real world application? A large part of engineering, can be figuring the best cost effective solution, which is still good enough. Its also worth considering, that brakepads is a fairly frequent consumable, in contrast to e.g. the caliper, and the brake line.

Clearly those in the industry can identify these parts. If the buyers for Reilly and Autozone act on this information then this will help drive industry change.

I did have a set of pads fall apart. It had rusted in between pad and plate. I do wonder though if those hooks decrease or increase chance of rust forming and glue then having nothing to hold onto

I would have liked to have seen a shear test that matched the directional forces in real life. My biggest issue with brakes is how quickly the pads break down. Not how well they stick to the backing plate.

I've had the same tbh. I think I need to swap out for a hotter pad and revise the cooling flow. Even RSL29s struggled to cope and that was on Eagle F1 Supersports, not even track day tyres or slicks.

how fast the pads breakdown or wears off depends on hardness of the friction material... a stiffer hardness will give less friction but better wear compare to softer material which has better friction but less durability....

What are the rules they are playing ? I am not sure if I should like such content where a manufacturer develops his own test methods to show that they are better than other - in their own defined test scenario. When are those sheer force appearing in real world usage ? Those pads sit on their metalplates holded by the caliper and brake itself. Feels like a theoretical test to look better than the other and I guess the others would now come up with their tests where they look better. If glue is the issue get rid of that glue, if heat is the issue look for a better glue in hot environment cause there are glues that work quite well or did I miss that most space shuttles were able to land quite safely ? Maybe 1% crashed due to failure but not sure if that has been caused by glue that did not work anymore. At least the space shuttle heat protection went through high heats at least once every mission if they had survived. And here our mechanic has not observed bad brakepads , even the certification engineers that have to check the cars street compliance biannually have not found much complains about brakes in general except if they were not maintained anymore or brake pads / rotors have been used too heavily and had to be replaced cause there was no brake pad anymore or the disc has become too thin.

Several of the aftermarket pads are being marketed as OEM replacements but don't have the mechanical gripping that true the OEM pads require from the manufacturer. You as the consumer might think you're buying OEM pads that are just as good as the originals when they technically aren't and you'd never know the difference. The video isn't saying that all brake pads everywhere should always be mechanically secured, it's pointing out that companies need to be more clear when slapping an OEM label on their product when it doesn't match the OEM standard.

I think that's fair! I think best case we do the same test with each of the different brands (we did this for the previous video).

Only personal experience I've had with friction material separating was a set of new pads my dad put on my ma's Mustang, they were mechanically attached tho

Great informative video as always! I just literally ordered new pads from a brand name, but will be wondering if they use adhesive or mechanical backing 😐

i've never seen brake pads falling off the backing plate. catastrophic brake failure is a scary thing to worry people about but it is extremely rare. if one brake pad falls off you would still have plenty of redundancy to safely bring your vehicle safely to a stop. remember each wheel has a front and a rear brake pad. GM had a weird recall where brake pads were not installed on one wheel and people drove the cars for tens of thousands of miles and never even noticed! These tests are weird they baked the pads for Multiple days at over 500 degrees which is a temperature your brake fluid will boil and you will have so much brake fade that you would likely pull over the side of the road until your brakes cooled down anyway! Not saying don't do your research on what you are buying but if you buy from a major brake supplier like AC delco, Raybestos, Akebono, brembo, Bosch you are probably 100 percent fine. I don't trust parts houses brand brakes as you never know what you are actually getting.

I don't really think it would change the answer but testing brake material by holding it at temp for hours or days is not real world at all. Repeated heat cycles would be much better.

Your choice of “quality control” was cherry picked to be worst case for adhesive and best case for the mechanical. What if the nail only protruded a very small amount instead of an inch? I don’t think you can argue that quality control is more of an issue for either method.
@EngineeringExplained

It's just one nail to illustrate a point, if there were a bunch of nails, even with small protrusion (like the pad), you get a better hold (for shear forces).

Will definitely have to check out NRS when it comes time to do brakes on my newer Silverado 2500. The dealer already replaced all the pads under warranty due to excessive brake noise, but even with a 'new part number' pad I had to wait for the noise returns. They want to do pads and rotors now but its no longer covered by warranty, and I''ve never paid someone else to put brakes on the many vehicles I've owned. I've had good luck with many aftermarket pads before, I'll have to research and see if I can find out if they are mechanically bonded or not.

No idea what attachment method they use, but I’ve been using Akebono Euro ceramic pads on my Mercedes and they have been great. Much more linear pedal feel, last forever, and almost no brake dust. I’ll never go back to oe pads. The last set I had used were one of the oe brands and the pad ended up separating from the backing plate from rust after about 4 years. The Akebonos have been on for 4 years so far and no issues.
