A friend brought her car over for me to check out. I drove it around the block, during braking the car kind of surges. To me it felt like the rotors were shot. I took the wheels off today and the rotors appear fine, brake pads look almost new. It is a 97 Buick Century. What else should I look for?

Does the brake pedal pulse when you're stopping? That can be a wheel bearing going out. Otherwise, maybe the wheel cylinders on the rear brakes.

I'm not a mechanic, per say, but it does sound like rotors. I don't know if warping of them is visible or not. Tryin' to help.

ETA- My '97 Honda eats rotors like candy and it sounds like you have the same situation.

I don't think the pedal pulses(have to take it for another ride around the block to check that), but the entire vehicle does. I'd have thought for sure it was the rotors. I haven't tore into the rear brakes yet. I will check those next.

Possible problem with antilock brake sensor or controll module. If it has a false reading of a wheel locking up it can reduce pressure to brakes and then reapplie it..
