Hey guys, so I was on the track again on Sunday and I think I might have damaged my rotors again. The car still stops fine but they look a lot different now and I'm afraid that I might have burned them or something. Can you guys take a look at the picture and tell me if you think something is off?

If they aren't scored, and you still have linings left, and there's no signs of cracking between drilled holes they will probably go back to looking normal with a few hundred miles of regular driving

So there are definitely no signs of cracks anywhere near the holes. It is slightly scored though, I mean it isn't perfectly smooth but you can only feel the grooves if you run your finger over the rotor. And what do you mean by lining? The pads have tons of life left.

Old Yellow

Yeah pads. I'm old, and used to be poor. I used to have to buy relined brake shoes for my raggedy *** cars.

Lining is the friction material bonded to the steel backing pad. Light scoring not a problem.

I guess I'm still poor: Relatively speaking.

Unless that pic has a large amount of distortion, it looks like the hole pattern is wrong for J55 rotors.

When you say damaged again, that sounds like these are not OEM. Aftermarket perhaps?

Yeah they are aftermarket, I'm not exactly sure of the brand.

They look glazed from braking I would have them cut if your having problems stopping the car.

Old Yellow

From what he said there doesn't seem to be a need. Cutting them down will almost guarantee future track problems.

Glazed, no big deal.

Basically you overheated the pads and the resin melted. It's now deposited on the face of the rotor. There are two possible reasons this occurred...

- You're braking on the race track like you do on the street
or
- You're driving at a level where you've exceeded the capability of the pads you are using.

If the former, you need to work on being fast and smooth with brake application and release. You cannot easssssssssssssssssse into braking.

If the latter, you need to buy pads suitable for track usage.

I am using Hawk HP+ pads which are suppose to be good for track use. When I brake on the track I definitely press harder than I do on the street but I rarely press hard enough to get the ABS to kick in, should I be quickly stabbing the breaks before corner entry? I might not have the right technique here.

They look like Swiss cheese......

HP+ is at best a marginal track pad. Good for a track that is not technical and a driver that is not pushing the car. You need real brake pads.

As far as technique....Fast and smooth on, fast and smooth off. Not an "on/off" switch, but certainly a lot faster application and release than you'd use on the street. No need to get into ABS. Ideally you threshold brake.

Nothing wrong with that rotor. Keep driving it. Even if it has some heat checks it would be still be good for 15K or 20K miles of street driving.

If he tracks the car enough he'll have to go with new rotors and brake pads, nature of the beast. If they are cheap rotors sooner than later.
