Anyone get vibration in the steering wheel under light to mederate braking at speeds over 50mph?

 

i get a slight brake steering shake at 160-170

 

Pipe down lambo boy!

 

Shouldn't happen Britt. Usually it is caused by poor pad bedding. See this link.

It is either one or two things, your ABS working or as Tim said it is the rotors.

 

Likely pad material deposits on rotors.

 

I had a similar issue, and it turned out to be my front rotors. I had them replaced, and the shimmy was gone.

 

I currently have the same problem . . . vibration when braking at high speeds (over 100 mph). Dan at Speed Gallery and Jamie at Race Technologies diagnosed the problem as brake pad transfer to the rotors. According to Jamie, it probably happened the first time I braked hard at high speed. Unfortunately, it will likely happen again if I merely clean or replace the rotors and put on a new set of the Pagid performance street pads packaged with Brembo's brake kits. According to Jamie, the only long term solutions are: (1) to switch to a lessor performing pad, that does not transfer to the rotor, or (2) switch to a Performance Friction Ceramic pad that performs even better than the Pagid pad, but squeeks during slow speed stops. While I would prefer to avoid squeeking, I am going to give the PFC pads a try. They are on order. Jamie at Race Technologies has been great in dealing with this issue.

Yes, Take a look at them, if so flush them out.

 

Warped rotors perhaps?

 

that's my bet.

 

Guys, read the link. Warped rotors are extremely rare. What people attribute to warped rotors are usually pad deposits.

Craig, the way to prevent this is proper bedding of the brakes, not new brakes. Once it does happen, if it's bad, you might need to grind or even replace the rotors but proper bedding should avoid the problem next time.

Ask me why I know so much about stop tech?



And now this braking announcement (pun intended), the Bling King has struck again! ... Film at 11.

 

Sometimes you can get it to smooth out by making a couple of hard stops from about 100 mph down to 50. Then drive a few minutes to cool the brakes before you stop. I've also had luck pulling out the pads and lightly hand sanding the rotors with 240 or 320 grit sandpaper. If the pads look glazed you can also sand the pad contact surface under running water.
Try to never come to a complete stop with very hot brakes.

 

I had the same problem on my Carrera. Every time I washed the car, the rotors would rust and the pads would transfer material to the rotor. This occurred mostly if I'd let the car sit after washing it. Make sure you take it for a spin after washing it to prevent this.

My only solution was to turn the rotors and switch to Pagid blue pads. They didn't do this after washing or their coefficient of friction was high enough to clean the deposition on the rotors.
