This guy is so easy-going, clear, knowledgeable and unpretentious on his explanations that makes me wanna spend cash supporting him on Patreon so that everyone can have the joy of looking at his videos. Keep it up Mr. Geese!
YES THE DRUMS!!! They don't get enough love and this topic doesn't get enough love, thank you for sharing your knowledge on vehicles and addressing what the mainstream leaves out. -Kevin
As with your other videos, great content, quality, production and immensely informative without being overly confusing. I was hoping you to touch the topic on brake distribution/bias as I'm currently having issues fine tuning my set-up (an old Toyota 4wd vehicle with disc and drum combination brake system) as the proportioning valve has already rusted out and fitted an aftermarket one. Keep it up and Thank You, sincerely.
EnclaveSoldier; Honestly man, I bet they sort of do. A lot of cars already have 3g connectivity built in and it wouldn't take too much to have a "back door" remote code installed. I'm not saying that it is going to happen or that it will, but the tech is here and it can be hacked. Anything with a connection to the internet can be compromised, trust me.
@@Phenom98 ... that technology has been around for about a decade. But its not the brakes, they can remotely slow down the engine. Of course it has to be a connected car. But even the most mundane cars today are satellite connected
Thanks Dezoris for another upload. Love this stuff, I'm glad we're entering in age where truth is King. This is probably my most anticipated series of videos I look forward to.
I never thought that you could talk about breaks for 30 min but I was wrong! Good job mr with this video especially with presentation and explanation for illiterates like myself... brake hard find god!
As always a quality, informative video from the Goose. Love the depth and breadth of information, and the lack of clickbait unlike everyone else on RU-vid. Keep it up!
Saved this video for a few days. Reminds of the point you made on the smoking tire pod cast about putting tons of work in on something and not getting the views
Another great video. A layperson like me can go from being completely ignorant of car mechanics to someone who is at least conversant in them by simply watching these videos. A video Encyclopedia Brittanica of auto mechanics. Could not recommend more highly.
I'm going to point people to this video when my subscribers ask me more detailed questions on brakes. Better than me making a video like this, so thanks!!
I almost didn't watch this because I thought "Meh... I know all I need to know about brakes." Wrong! I definitely learned a few things and the presentation is just so enjoyable. Love your work, Mr. Geese!
Is this a friendly overall description of braking systems, accessible to the layman? Yes, for the most part this meets that goal. There are far more errors/inaccuracies along the way than I’ve come to expect from SG’s vids. ‘A’ for effort, ‘B’ for execution.
Wow!!! I am a female who just came across your videos because I am looking to replace my 2013 GMC Arcadia Denali because it’s a piece of shit. I love you reviews and I can’t get enough of your videos. I actually sit and watch almost all of your videos I can’t get enough.
This was such a great video. Excited for more! I have an F-Sport Lexus that comes with two-piece front rotors but really had no idea what that meant, other than increased performance. And it's true, with the windows down, turning at slow speeds causes them to make ticking noises. Other owners have complained and the "fix" was to put on smaller non F-Sport one-piece rotors. I'd never sacrifice braking performance over tiny ticking noises I rarely hear.
Thought I knew a lot about breaks. Knew I didn't know it all. Though I might learn something new. Knew I'd at the very least be entertained by SG. So I watched, and I learned something, and I was entertained. Doesn't get much better than this!
What you might not realize is that the brake reservoir is not only the storage place for the brake fluid, but its level is used by your mechanic to gauge how worn the brake pads are. As the brake material is consumed the thickness of the pad is reduced in thickness, the brake caliper has a piston that is forced out causing the pads to clamp the rotors. As the pads wear, fluid level in the reservoir is reduced and is used as an indicator of pad wear. Therefore, it’s generally a bad idea to top off the reservoir .
i usually don't sign in, subscribe or like a video, savagegeese's videos are so good that i have done all three. he deserves more views and likes than other car reviews, pls share with your friends so we can get to see more of these top quality videos.
You know what this video made me realized? Soon enough we'll have no way of explaining how these things work anymore. The all-in-one GM brake system is a perfect example. "Here is a proprietary black box doing magic via Pixies and we can't open it because it would be DMCA infringement". Let's us rejoice we can still have quality videos about cars like that.
Guys on the IS owners' forum on ClubLexus are always complaining about the short life and squeakiness of the F Sport pads that come from the factory. Some end up switching to aftermarket pads like Akebono. I wonder how much of it has to do with the pad material itself and how much has to do with proper bedding and maintenance. I had some squeaking last winter, and got it fixed by having the rotors resurfaced. It is important to understand that having the additional friction and bite is going to have some tradeoffs - more grabbiness in cold weather, occasional squeaking, shorter life - similar to how high-performance tires typically last a shorter time and are louder than grand touring tires. This was a super-helpful video Mr. Goose! Thought I knew more about brakes than I actually do. :)
Very informative and comprehensive! Explained concepts that most others have left out when it comes to brakes and certainly showed me much more than I thought I did about brakes. Keep up the good work! Subscribed to your channel!
The production value is amazing as always and this will be a resource I point the uninitiated toward in the future. I knew back drums were more "practical" as far as the service interval, but I was unaware of the seizing issues with low load applications like the prius(es?). Always great to learn something new.
Dude, thanks for mentioning the dust boots. I just replaced a caliper for that. 3 month later I did new rotors and sure enough it was burned again. Just from daily driving and 2 Autocrosses.
Your explanations are very good and well though out, clear and to the point. Sg no Bs. Please talk about how moisture in brake fluid rusts components. And how carbon disks have zero dust.
It's not completely comparable. This is more informative about brakes and the implications regarding cost etc. than any EE video, but also much longer. And he wanted some easy views so he made a video with disadvantages of manuals, not why they suck. Purists can calm down with "manual or die", even though like EE I prefer manual.
That's an obvious fact (mostly because 1 video is 30 minutes long). You called it "better" and were making a point of comparing things with different goals. I found there to be very few "savage geese" in this video btw ;)
You said that this video is more "Engineering Explained" meaning it explains more engineering. A video that's 5 times longer has more content. Just like a bigger container "contains" more.
Bedding in new pads and rotors is important even on every day drivers too. The bedding in lays down a even layer of pad material on the rotor surfaces, uneven layers of pad material or DTV are confused with rotor warp which is used to describe all kinds of brake issues.
I had AP Racing brakes installed at my crappy tuner. For some reason I don't understand they had to machine some pad edges off or something. Then either the tuner didn't heed my warning about break-in or it's some geometry issue, but braking created a lot of vibration on those new, expensive brakes. And they also made an awful noise, making me realize they aren't equipped with noise-reduction plates or such. I hope they at least have sealed pistons. Should be street-level brakes, in case AP Racing even has those. In any case, I learned some things from this video that I didn't know before.
Gimme a brake! No really-that AP caliper is major eye candy. Bet I could find a good home for it on my Fiesta S 4-door! (I’ll keep the drums on back for the “stoppies”) Like the selection of rotors too. All well explained, good details, nicely done.
I just subscribe to your channel and I don’t know why I didn’t subscribe a while ago because I have been watching your videos for a while. This video series I love a lot because I haven’t put must thought into the many different parts of a car before. Later on sometime this year I’m going to get a performance car (probably a Mustang GT) lol. One of my reason for it is because I want to do some track days and be better able to drive manual around everyday since my car will be a daily driver. What has me worried for a while was the fact that, when you put a mod on the car it puts a strain on the other parts. How could I fix these problems? Your videos have given me the knowledge I need to not worry about it and how to approach them before I put a suspension part, engine part, or bigger tires on the car. Thanks so much for making these videos!
Yes, drums don't get much love any more. However, they do have some advantages over a disk system. Mainly, it takes much less force to achieve the same braking force. Which makes them better suited for a park/emergency brake application. When the brake is activated by a hand lever, it helps to have a system that doesn't require as much force to activate. I had a 96 Ford Explorer with 4 wheel disk brakes. However, the rear brake disks also had drums. It was a combination disk/drum assembly. The drum part was solely for the park brake. I also think that very large vehicles (like 18 wheelers) still use drums.
Another advantage of rear drums is that they hold the car more securely on the handbrake. Some manufacturers used to fit small auxiliary drums just for the handbrake in addition to discs.
Nice video. Are the animations something you find online or do you create animations somehow?? If it’s someone’s animations.... is it fine to use? Thanx. Just want to learn for my channel too
A drum brake can be very powerful and reliable in extreme off road situations if you can somehow keep it cool enough and clean enough. It's sealed nature can be a huge advantage if that seal is maintained. A liquid cooled drum brake system perhaps?
I wish I could remember where, but I did come across a liquid-bath brake system for a Toyota Landcruiser some years ago (although I think it was a disc-style layout enclosed in a fluid-tight casing.) it operated just like a wet clutch in a motorcycle - giving it the benefit of being sealed so dirt and sand wasn't an issue, and heat didn't seem to be a problem for it, what with all that fluid to help absorb it. I'm pretty sure it won't be available any more, though - it would be quite expensive when compared to an OEM system, and heaven forbid it has a bad seal and leaks. :-P
Speaking of pad bedding, some heavy duty pads actually come with bedding layer to speed up the bedding process to the point of just a few moderately hard stops will fully bed them in.
Thank you for this presentation on the fundamentals of brakes. I notice that Corvette has changed the type of rotors to reduce copper composition necessary to control heat and wear on the pads. Got to save the oceans, streams and lakes. The cross-drilled create a weaker rotor, don't they? Also they don't really vent gasses any better than non-drilled rotors. AF
So disks with drilled holes in it are for cooling and looks. Fine. So where are the grooves for? Isn't it that grooves like the grooves on a clutch disk are there to multiply the surface area and thus create more grip (?).
For the next video, you should explain rotor glazing with these street/track pads. Like it's almost just worth getting actual track pads and just changing them out for street for street driving. Or in my case, daily driving.
Another great video, as always. Just some F.Y.I. and comments: 1.) A.P. Racing is a subsidiary of Brembo. 2.) Please discuss the chromatic effect of caliper color and horsepower gains. Is it true that painting your calipers red makes them automatically 50% Brembo and adds 30 horsepower.
Caliper covers add 100% more brake power and lime green color is best for performance. AP is owned by Brembo but development and products are seperate. They do share some common components and manufacturering however.
I subscribed to your channel with alerts at about 70k, I just noticed the other day I wasn’t subscribed and had to resubscribe. Probably not the first time you’ve heard this but thought you should know. Also you promised we’d find out what turbowski drives..when’s that dropping?? Be well
Man I was just thinking about trying to find a video about brakes, and speak of the devil, look who uploaded a vid this morning. Awesome information. Quick question. Should I be worried if a car (05 Corolla) that has about 90k miles and never had it's brakes changed and the dealer said they "were not needed right away."
This was a PERFECTLY timed video for me as I am going to be making some changes to my brake setup soon. If possible, will you release the video on brake fluids first? I specifically want to know which fluid I should go with if I do mostly DD duties with the occasional track day mixed in? I am hoping to get less brake fade on the track and hope a change in fluid will help it.
Those AP racing calipers do actually have dust protection, IIRC they basically have a second set of (sacrificial?) piston seals just below the surface.
I don't leave a lot of comments but i had to leave one explaining how enjoyable i find your reviews. I watch many but i have to say yours are the most detailed,in-depth and entertaining.I found this channel back a couple of months and have watched every single one, each and every review is a absolute gem.
