It work very well, even on slightly warped disc by taking a little more time and les pressure. The only time a disc is no more useable is when they are too tin or the center fins are gone

Yes 40 for the rough part then something like 240 for 20 seconds each side for the finish touch

[@maximeberube7490]

I use the rougher grit i got because it's way quicker this way. I mean, if it take you 1 hours by disc it's way quicker to got some cheap one at napa. It take me not more than 5 minutes hammering the scale and another 5 with the wheel spinning and the grinder. I use a file in the processe to check if the surface is perfectly flat

[@Iowa599]

The thinner they get the quicker they warp.

When I was much younger I resurfaced hundreds of rotors. But, I used a brake lathe with a diamond cutter. We also made sure the finished rotor met the minimum thickness requirement.

[@theofficialdiamondlou2418]

That’s how I learned also. But I was thinking as a pre groove glaze remover this might work , but I’d use SS block with Diamond dust . To get a faster cut with less pressure , and material removed.

[@3rdpig]

I used to have a tool called the Grizzly Grinder, which did the same thing but in a more controlled fashion. It worked well for making them smooth as long as they weren't deeply grooved, but it was of limited value taking out the high spots. Note that while a lathe can remove the high spots that doesn't "unwarp" the crystalline structure of the metal. Also note that grooves don't stop the brakes from working, as long as they're not so deep as to weaken the rotor just put the new pads on and let them wear in. Or, just buy new rotors, most are dirt cheap.

You should try polishing the rotor brake pad surface to a mirror like finish and do some stopping distant checks.

[@averyalexander2303]

Probably wouldn't show any meaningful difference. If the brakes are strong enough to lock up the tires, there's no more stopping distance to be gained from strengthening the brakes further. In the vast majority of cases, upgrading the tires and suspension and fine tuning the brake bias is what will improve your stopping distance, not upgrading the brakes themselves.

[@Tomatolover120]

​@@averyalexander2303I think the idea is some roughness is better than completely smooth since the pads will catch in the rough parts better. Like sandpaper on wood vs sliding a piece of copy paper on wood.

[@averyalexander2303]

@@Tomatolover120 I could see that being true, my point was simply that it's irrelevant as far as stopping distance is concerned and wouldn't show a meaningful difference in testing because slamming the brakes will lock up the wheels regardless of the rotor's surface finish. The surface finish could definitely affect other aspects though such as how the brakes sound and feel and how long the pads last.

[@cm5838]

Polishing the rotors would have the same effect as glazing, reduced friction which translates to reduced braking ability

[@JT-4real]

The "warping" can also be from a crook hub bearing or the faces of the disc and hub are not clean. Most cars I work on I see that other mechanics don't clean the hub face prior to fitment of rotors.

[@zeropointzero]

It's more common than it should be. "I just had new brakes put on and there's a vibration when I press the brake pedal." "Yeah, here's your problem, the lazy cunt that installed your brakes didn't clean the chunks of mother nature's excrement off the hub surface."

[@2bisc]

My front brake pad worn out and the metal back plate carved the rotor surface with shallow grooves. I simply replaced with new brake pads and drove normally. At first, there were rubbing noise and pulsating feel when I applied the brake. After a few days, the rubbing noise and pulsating feel were gone. The brake pads eventually "grinded" the damaged rotor surface into a shinny (not flat though) surface.

[@DarkIzo]

perfect opportunity to do brake tests on bedded-in versus non-bedded in

[@martin1649]

By feel it's noticeable. when you know how new disc and pads feel, you'll know something is wrong. I hopped in a friends car whose brakes were done and he's only been braking lightly for a few hundred kms. I didn't feel like the braking force was good. Took it for a spin, couple of 80-50 hard slow downs, cool, then 3-4x 50-0 hard stops, then they started smelling, drove some more to cool it down, one more 80-50 slowdown, then perhaps 2-3x 50-0, cool and suddenly it braked as it should. A week later he said he noticed the braking power increased significantly.

Nice experiment, might be useful for removing light wear, but probably not the most effective for heavy wear. Probably not a good idea to take too much metal off the thickness either. I guess this is kinda a hack for someone to resurface a rotor at home without access to a lathe to avoid having to pay a shop to turn them or buying new ones. This seems like something I would do, but would definitely measure the thickness afterward to ensure it's even and not to thin. Give them a 2nd like without having to pay a shop to turn them. I would definitely always turn them myself if I had my own lathe, unfortunately I don't, and I can't take my own stuff to use the lathe I work on at the machine shop.

They will always stop a car as long as there is material (barring it being like paper thin or something) even if you go well below the minimum thickness. The problem is heat dissipation; a thinner rotor won't have as much mass, and will warp quicker.

If your rotors are warped but not too bad you can heat them up and cool them off flat again. You need a good stretch of road where you can get them hot with light braking. And then brake very gently to a stop, light enough where you don't feel the steering wheel shake at all. If it shakes once you gotta start over. After that just sit there for 10 minutes or longer till the rotors have cooled down. I usually do it on an empty highway and pull over to wait it out. As a tech I'd do it just before I did a brake job on my own vehicle and was gonna turn the rotors on a brake lathe.

[@JJFX-]

I'm struggling to see why this would automatically remove warping. I'm not saying you're wrong, but unless I'm missing something I don't see why continuous light braking would encourage the metal to flatten?

[@1985cjjeeper]

@@JJFX- It's not "automatic". It's just heating the rotors up good and hot and letting the metal settle back the way it was before it got hot and warped during continued heavy braking. By just barely engaging the brakes you're able to get the rotor hot without increasing the warping. Metal has a crystalline structure and it likes to line up a certain way. If you've distorted that structure, heating it can allow it to return back to the shape it was initially formed in. Same concept as using a heat gun to fix a dent in a body panel or what you see with nytinol metal if you bend it and then heat it, although that is an extreme example.
