bbqen2 Posted December 29, 2004 Report Share Posted December 29, 2004 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? Dan Quote Link to comment Share on other sites More sharing options...
Intlcutlass Posted December 29, 2004 Report Share Posted December 29, 2004 Make sure the caliper bolts are tight. That clunk noise could be the caliper shifting outta place due to "slackness" in the bolts. Quote Link to comment Share on other sites More sharing options...
bbqen2 Posted December 29, 2004 Author Report Share Posted December 29, 2004 I backed them out and then re-torqued them. I'll drive it awhile and see what happens. The top ones on the back caliper are a SOB to get a torque wrench on. Quote Link to comment Share on other sites More sharing options...
