Brake Problems

arivera · 04-24-2003, 05:51 AM

Okay, I have a 97, V6 Mustang and my problem is this:

for about the last two weeks, I've noticed that whenever I apply the brakes, I can feel the brake pedal pulsating and the steering wheel vibrates to the same 'beat'. And the harder I press the pedal, the stronger the vibration.

This happens no matter whether the brakes are hot or cold.

I had the front rotors machined and the pads changed about four months, and I had the same thing done to the rear brakes two days ago. Still happens.

Any ideas?

Same problem so I installed 2003 Cobra 13" brakes. It is gone now.

Hmmmmm. Not a bad idea but do you know what's causing it?

How thick are your front rotors? Thin rotors will heat up and warp back up in no time flat. Also, hot spots (hardening) can cause a pulsation.
Where did you get your rotors turned? Did they measure them? Chances are i bet your rotors may have been mismachined, are undersize, or have hot spots. If i were you, i'd get a couple new front rotors.
If you have a dial indicator you can check lateral runout of the rotor on the car and the specifications should be in most manuals (100% it's in the Ford Shop manual).
