I did a brake job on the wifes car a 93 lumina a couple of weeks ago. She says that since then there is a clunck sound after she has driven for awhile and usually happens during acceleration or going up a hill. I've heard it also. It sounds like it's coming from the rear of the car. It only does it once and then it is ok. I changed pads and rotors and also one caliper on the rear. On the front I replaced pads and 1 rotor on the drivers side. I'm guessing that one of the calipers is sticking on the slides until the brakes warm up. I'm thinking I just used regular grease on them, and it's cold here. Does that sound logical? Any other ideas?
