I was told it was warped front rotors, but I have replaced the front rotors twice with no change in the problem. I have also put on a new master cylinder without making any difference. It is getting expensive, Help!
Kevin, a pulse in the break pedal tells me the problem comes from the REAR rotors. Have someone check the runout on the rotor to confirm the diagnosis. I’m sure you will find your problem there.
