Brake Pedal pulsation - And... . SA Remarks Gotta Read

After the brakes were replaced, did you do a break-in process on the pads? If not, I would do that and see if the issue goes away.

I realize the instructions here: http://www.zeckhausen.com/bedding_in_brakes.htm are written for aftermarket pads/rotors, but the process should be used for any pads/rotors after replacement for proper brake operation.

If this does not get rid of the issue, I would suspect a problem with one of the rotors.

Thanks for the reply. I removed my rant on the subject. Dealer came through and replaced the recently installed rotors as part of my extended service agreement.

I did read the article on bedding in brakes and found it interesting. I have always been told never to heat up new brakes as it will form a crystalized surface and the brakes will never be fully effective.

But you know that was probably asbestos brake pads and cast rotors not the newer materials in rotors and in brake pads.

Service tickets says they put rotors and pads i guess to keep as a matched set even thought he last ones had about 2500 miles on them.

It is certainly possible to glaze the pads by breaking them in incorrectly or overheating them. However, doing it properly really makes a difference in brake performance and longevity. Is it OK to just slap new pads and rotors in and drive?... Sure. Most people do it that way. But they are leaving so much latent braking performance on the table that way.

New rotors have a very slight criss-cross pattern across the surface from the final honing/surfacing process. This provides a good uniformly rough surface to bed the pads to during break-in. A new set of pads is optimal when the rotors are replaced to facilitate a perfect mate between the pad and rotor surfaces. So doing the break-in process as soon as possible after rotor replacement is a good thing.

Hope your new rotors do fix the pulsation issue. Keep us posted.

So did it fix your problem?
