Chattering while braking on a 2003 Mazda Protege

[zipster1967]

My dad's Mazda Protege vibrates when braking. No problems while accelerating and the brakes are fine. Pads and rotors. I am thinking bearings but I would suspect that it would grind or vibrate all the time or when turning but it only happens when your braking. Any ideas on where I should start checking for the cause of this problem? Any suggestions would be greatly appreciated.

Sounds like your rotors may be warped.

+2 on the rotors. But somebody told me to try beading the brakes again, sometimes beading eliminates this vibration while braking. Another guy confirms he only changes pads and the vibration is gone. As for me I had this and just changed both rotors and pads and it ok now.

Retorque the wheel lugs to factory specs. More rotors warped due to over-tight wheel lugs than to any other cause.
