Excellent process used. We live in a 'throw away world' and the art of engineering is slowly dying off, however, as seen in this video the working life of a brake disc can be extended if engineered correctly. The obvious benefits are less cost when compared to a new disc, less waste and the feeling of job satisfaction. It's a pity other people don't appreciate the process and skill used to engineer the discs as shown here. In summary, good explanations of the process used and the most critical point is that the process makes the car safer to drive

It's not "dying off". It's simply adapting to the commercial realities. We've actually never had so much engineering before as we have today.

Was also thinking of building an adapter for this , But I found a way to do this on the lathe ,The center hole is clamped on the outside jaws of a 3 jaw chuck and indicated with a dial gauge , resurface the face then turn the large diameter in the rotor "this is for a true surface with the turned rotor face at 90 degrees for clamping in the chuck " Then turn the rotor to complete using the outside jaws and indicate then resurface . Works well for me !

Excellent video! If I could add my 0.02c worth. When you're running the lathe tool across the face of the disc you are essentially introducing a 'thread' or spiral like pattern to the surface. When the brake pads are applied they will try to 'screw' into (or out from) the center. This can cause squealing until the the discs burnish in again - sometimes they keep squealing. I've adapted a home made chuck grinder with a 3" sanding disc attached and finish the brake disc face with an omnidirectional pattern - sort of a hone finish. That seems to fix the issue.

I’m about to embark on similar, but my lathe is much too small. Fortunately I have a decent sized mill that I’ve just trued up the ways on, so making an arbor to mount in a BT40 facemill arbor will be this week’s job on the lathe. And for those saying it’s a cheap part, it isn’t if you buy rotors that are made from decent metal, these stop much better even when warped/hot spotted and are worth resurfacing.

Hi Peter, thanks for watching friend. I didn't know the compound was square, but I wasn't using that to make the cut, but the lathe's cross slide that should be fairly well fixed at 90 to the bed of the lathe.

Holy cow! That is a lot of time and effort to resurface your rotors! Most garages or auto parts stores will resurface your rotors for a nominal fee. However, as a former mechanic, we generally would replace rotors with the pads because they are relatively inexpensive and helps insure the brake job won't come back on you because of a pulsation in the brake pedal. Besides, we recycled all of our scrap metals.

I much prefer the on car resurfacing. Because it cancels the imperfections of the wheel hub too. With new ceramic pads, hybrids and electrics, rotor wear is not a big problem anymore. 150 000 km on my W202 c class, with just half worn ceramics pads, rot wear being less than 0.2mm the car will be junked before another rotor change. 500 000 km pads/rotor on hybrids is common. Regenerative braking is more than enough for most normal driving on flat land. Brakes are now mostly for emergency braking. As for the price, just don't buy them from the dealer, there are much cheaper and better ones for most cars. Go for low dust low wear ceramic pads they might be more expensive but the last way longer to more than compensate (I experienced ATE's and EBC)
@ChrisKyriakides
@ChrisKyriakides Год назад
Good job! Not sure if it’s been mentioned elsewhere but it may prove of value to mark/spray a thin layer of say red paint on the low-point (or even over the entire surface of the disc if the low-points and concentrical over the entire surface). That way (as you are skimming more and more across the entire surface of the disc with each pass) it should serve as a visual indicator as the paint mark will progressively disappear. You should be able to see the paint even when the disc is rotating at speed; when you have skimmed low enough to approach the low-point by then the paint would have almost disappeared completely. At that stage you will then have to rely on your micrometer to measure how close you are to being done. In effect it should speed up the beginning part of the skimming process with less risk of accidentally over-skimming between measurements. I hope this proves of value.

Dear Friend, I have done something similar to this that you show but only to remove heavy rust scale, however, To give good service life the surface must be made smooth like a ground surface. The surface you leave will not stop well and tear- up the linings/pads and shorten the service life.

No disrespect here but I do have a suggestion. I have turned rotors almost the same way you do. You had me till after you faced off the steel tubing. Lol. I also chuck a piece of steel tubing in the lathe and face it off but then, I put the outside of the rotor up to it and run a bull nose live center up to it to hold it in place. And it's also centered up. Then you can take both cuts in the same setup and avoid rotor runout from multiple setups. Hope this helps. 👍

a used hub flange can be used to bolt the disc to the lathe Even a new one would be cheap enough to invest in as a tool for resurfacing discs, you could add extra pcd patterns and use spigot rings to centre other discs.

Hello sir, your video was interesting to watch and do some learning from! We had a longtime family friend who was a mechanic, machinist and tool maker at his home shop his entire life. If he didn't have the tool, he made it! Unfortunately, he passed away several years ago but the memories of his shop, work and spending time around him will last forever. I'm curious, what is the size of your lathe? I'm getting ready to purchase one for my shop and don't want to spend the big money only to find out that I didn't do my homework and ended up buying a tool that's not large enough to fabricate or repair pieces on. I'd definitely like the lathe to have the ability to turn automotive rotors on but will use it for ATV and ATC parts. Thank you!!

A bit of advice for machining your own brake rotors/discs, make sure you get the brake rotor/disc machining tolerances BEFORE you machine them. BEWARE, if you machine too much material off, you can cause a loss of stopping power or COMPLETE BRAKE FAILURE, which will result in severe bodily injury or a tragic fatality. So do your research before attempting this type of machine work.

I'm assuming you have never heard of a brake lathe that is not only designed to do this but also comes with pre-made adapters. The time it took to make the adapters and resurface or Skim as you called it is unrealistic. Might as well purchase new rotors. The other problem is the hub on the car could have runout. The best method is to use an on the car lathe like the ProCut. It also didn't do any good to skim the surface where the wheel mounts but more importantly would have been to skim the surface where the rotor mounts to the wheel hub.

You can replace the bolt by pushing a plate against the disc with a live center. Only need to turn the register diameter and face, I use old engine pistons for that. If you mark the orientation, it can even be rechucked in a 3 jaw chuck and still run true enough.

I work at a VW workshop in Sweden. If the brake disc is bad we throw it away, but its because we dont have a lathe, and still the cost of the labour would still exceed the cost of brand new discs. We cost about 2000 SEK + 25% tax an hour wich i think is about 170 dollars an hour + tax. But if you have a lathe and you either have it as a hobby or a really low labour cost its probably worth it depending on how bad the disc is. I have actually taken a few throwaway discs from work to use as training material on my own small hobby lathe.

I am retired and I have time but little money. I am fortunate to have a 16" lathe with a large four jaw chuck and have successfully resurfaced my brake rotors many times. Initially, I set up the rotor by holding it in my chuck and indicating off the inside face of the rotor (the face that clamps to the wheel hub); I then machine everything parallel to this. I like your idea better. Once the jig is made up, it would be much faster to set up and get the job done. I do have a question. When you face off the the rotor hub before you flip it around and clamp it, there will be a raised area that you can't machine because the clamping disk is in the way. The raised area will prevent the machined face from touching the jig when you flip it. I am missing something, right? Did you machine the jig to except the unmachined raised area? I hope I am being clear. Thanks for sharing.
@FloweringElbow
@FloweringElbow 5 лет назад
Peter, thanks for the comment. I think I get the question... The outer nut and dist of the fixture, that clamps the brake rotor on, is onto an indented surface anyway. That is to say, that surface that is covered up, and therefore cant be skimmed, doesn't actually make contact, and is slightly inset - at least on my disk brakes... As you say, once setup, you can actually do four disks quite quickly. Loads quicker than dialing with a four jaw chuck each time you flip it. Cheers, Bongo.

That is a lot of machining just to make an adapter to fit one car. I know a good shop, with a brake lathe, another friend of mine gave me a set of spare rotors, and I had them machined for 15 pounds each. New rotors will be 50,60 pounds each. Normally, I do not even bother to machine them, if you get to the brakes before it went metal to metal. The ridge where the pads do not touch, I just remove it with a hand grinder.

I can beat that Martin.

Then you can take both cuts in one set up and avoid the risk of rotor runout from multiple setups. 😉

I have machined several discs and drums with no problems, just bare in mind as others have said about minimum thickness. I made my arbour differently to yours. I welded my mounting flange onto the middle of a fairly stout round bar, then machined the whole thing between centres. That way I could mount the disk, machine one face and just turn the arbour round and machine the other side. Don't suppose it saved any money but it gave me satisfaction. Keep up the good work.

Flipping the disk is no good idea. Both surfaces have to be made in the same clamping. Did it on my RX 7 SA rotors, worked flawlessly. Just used a normal chuck, no exta fixture.

Nice money saver. One extra thing I would have done though, which is to use the dial indicator to mark the high and low spots before removing the discs from the car. It is reassuring to find the same spots, with the same runout when you chuck the discs up. If there is a big difference, there is another problem, maybe in the hub.

You could reface the hub to match the rotor

It’s a lot easier to leave the rotor on the vehicle and just use a grinding disk on a angle grinder and one should always mike the thickness of the rotor to make sure it is within safety limits which is stamped in the rotor hub most of the time

I would certainly do this until the limit of disc. It would be a good project if you are doing up that vintage/classic vehicle and parts were not readily available - weekend project. The limit dimension is given(I think) on the disc..?? Could you do a clip on machining brake drums and clutch flywheel.

Good morning Mohabat, thanks for your comment. Alas, I don't have a vehicle with drum brakes, and have yet to need to do a clutch (though that might change in the future)… I think the flywheel usually lasts through a few clutch kits on my little vw caddy van. I'm on clutch #3 so wont rule it out at some point... I don't recon it would fit on my lathe though - without taking out the gap ways at least. Thanks again, Bongo.

Think I'll have to leave this to the professionals who will probably charge me more than the cost of new discs hence why most people bin the old and replace with new.

Its not only the tools involved for this Job but the Time it takes to do it. Most discs average £25 a side.... Its not worth my time to do it when the delivery driver can get here almost as fast.

@@digitalacid My rotors are $290 a pair. I plan to bring in a stack of used ones to a shop and see if I can get a bulk discount. The majority of the time is setting up the tools to machine one... once that is done, the other 6 or 8 should go quickly.

Looks like your making this a very complicated job. But what do I know I never turned anything bigger than 10cm on my lathe. You're result is great and that's what matters.
@FloweringElbow
@FloweringElbow 6 лет назад
Maybe I am over complicating my description. Essentially all I am doing though is chucking up a mini face-plate (the fixture) that can be trued to the lathe and then bolting each brake rotor to it.

I use a grinder , while rotors are on vehicle . Not sure if just shitter cast or always had so many inclusions , but fixed about ten over the years. Just lift and block front end , take caliber a off and wire tie for support. Can manually spin and grind or let car idle as you grind high spots. Not saying it's best method, but saved my father in laws 700-880 US by grinding his front rotor . Shop would swap out both and add brakes and time.

I think the job is less precision-critical than you're making it, but that's what machinists do.

After considering many projects over the past couple of years a lathe would definitely suit me better than a mill. Just keep on the local machinery for sale ads in your state and you can find some deals sometimes. Remember you'll spend a good bit on tooling as well so look for a combo deal.

This is very logical and straightforward. I have a crazy suggestion. Do you think you could make a 3D printed fixture to spin the rotor and then do the cleaning with a rigidly mounted but lightly cutting angle grinder?
@FloweringElbow
@FloweringElbow 3 года назад
Cool idea! I guess consideration would be needed to make the 3d print rigid enough...

they are "disposable , because "mom and pop" stores dont exist anymore. So they charge you "book labor" to resurface them, so its cheaper to just buy a new one.

It's anywhere from 10 to $20 to have a rotor cut depending on the shop you go to
