Driving with warped disks

[psycho]

I'm getting a vibration through the brake pedal when I brake at around 80kph. A bit faster or slower then that and I cant feel a thing.

I'm running fairly new ds2500 pads and Brembo Max disks. This problem started after their first trackday but I dont know how they could have warped as I didnt sit stationary with the brakes and didnt even park the car with the handbrake on.

Anyway, my questions are
1) How can I check to be sure it is actualy a warped disk and not something else?
2) Is it safe to continue to drive on them, I mean they still stop really well and the vibration is getting no worse?
3) If they are warped, can I fix them or do I have to bin them?

Cheers guys

I would say its just unlucky, they must have been cooked on the trackday, the only thing to do is replace them, you could get them skimmed, but there often no better and its expensive unless you have someone really good local!

Have a read of that. The guy that wrote it was on the Ford GT40 engineering team and worked with Ferrari on F1 cars, amongst other stuff. He's got a couple of suggestions to sort it.

Warping of discs doesn't happen at all according to him - it's pad material transfer.

Buy some new ones, and be gentler on the brakes.

When you did your trackday did you come in and put the handbrake on straight away?

I dont know how they could have warped as I didnt sit stationary with the brakes and didnt even park the car with the handbrake on.

Guess again? :lolup:

Well as long as they arn't dangerous to drive on I'm just gonna keep em in. I mean they still stop the car like reverse thrusters!

....hope it goes away
