dodgethis Posted August 16, 2009 Report Share Posted August 16, 2009 I have been having this annoying rattle noise coming from the right passenger side of the car. It happens every time when I go over a bump or whatever. I thought it might be something to do with the brakes. I went under the car and started pounding on the tire with my fist. I could replicate the noise just by hitting on the tire. That told me that it had something to do with the caliper or one of the bolts are on tight enough. I found out I can take my hand and gently shake the caliper and I can replicate a high squeal noise as the caliper grinds against the rotors by the pads. I was going to say is it normal that it can do this? I went to check the drivers side and the caliper doesn't even more or make the noise. What do you guys think? I thought maybe I should just go back out there and re-tighten the bolts on the caliper and should be done with it. The weird part is when I went to get it aligned I asked the people if they would check to make sure the bolts were on there tight. They reported everything was fine.

xtremerevolution Posted August 16, 2009 Report Share Posted August 16, 2009 Brake hardware. I replace them every time I do the pads, ESPECIALLY on the rear, because rotors that sieze up to the bolts are a HUGE PITA to work on. They consist of the following pieces: The rubber keeps the bolts from rusting to the caliper sleeves, but they also keep the caliper from rattling against the rotor. You should replace those regularly. The metal pieces keep the pads in place and keep them from clanking against the rotor. That kit is $15. If you live in a rusty area, I might also go as far as replacing the caliper bolts, since those rust up pretty easily. Make sure to literally COVER everything in heavy grease. I replace those bolts now every time as well since I've had the sleeves seize on me a couple of times even after applying a VERY liberal amount of grease. They're $5 for the kit, per rear caliper.

While speaking about the squeaking when going over bumps, am I need to be concerned about how the braking is? I haven't had an issue as they are new pads and rotors, but is there any danger associated with it rattling like that? Quote Link to comment Share on other sites More sharing options...
tornado_735 Posted August 16, 2009 Report Share Posted August 16, 2009 When I did my brakes, I got lucky and didn't have any problems getting the calipers off. Quote Link to comment Share on other sites More sharing options...
xtremerevolution Posted August 16, 2009 Report Share Posted August 16, 2009 Yeah, out in chicago its bad. the slider bolt on the rear calipers is consistently siezed up. you have to hammer it out in a specific way to ensure you don't bend the bolts. its a real pita if you don't do it just right. Hell, I even bought a refurbed rear caliper once and it came with that bolt siezed on! If it does get siezed, you'll need to disconnect both the brake line and the parking brake line, which is also annoying. At least inspect the bolts and sleeves each time you do the brakes and re-lube them as necessary. The front calipers don't use sleeves like the rears do, but you still need the metal shims.

dodgethis Posted August 16, 2009 Author Report Share Posted August 16, 2009 ok, I'll throw it on stands and take the caliper and rotor off and find out what the hell is going on. It sucks now because im going back to school. I hope she behaves for a while after this Quote Link to comment Share on other sites More sharing options...
Stevo Posted August 18, 2009 Report Share Posted August 18, 2009 I would recommend 4 or 6 month re-greasing of sliders. - 6 months if you drive the vehicle in the winter - If your area spreads salt on the road then I would opt for the 4 month option.
