Cadillac Catera and Cimarron Forum Discussion, Rear squeaking brakes ????? :( in Past Cadillac Vehicle Discussion; 6 months ago replaced my rear brakes (Duralast CMax), rotors (regular not drilled) and emergency parking brake drum pads.
6 months ago replaced my rear brakes (Duralast CMax), rotors (regular not drilled) and emergency parking brake drum pads.
After month driving i apply emergency parking on drive gear (0mph) and car start to keep going so i removed rotors and
readjust pads and after that its started to hold pretty good and still holding good. But now for a few week already, my rear brakes squeaking like crazy when im baking up and applying brakes.
I even tried one time to baked up fast and applying brakes HARD several times in a row to see if its go away, but its still squeaking, as soon as i switch to drive gear and start to go forward and apply-ed brakes - NO squeaking!!!!!!!!!
Any body know what that can be????? !!!!!!!!!!!
I'm not an expert on Catera brakes, but general principles apply. All squeaking is caused by vibration, and all brakes vibrate when they rub. Quiet brakes vibrate at frequencies we can't hear, but may very well annoy the neighborhood dogs. The trick to making them quiet is to change something so that the vibration changes. This can be adding (or removing) a shim, simply taking them apart and cleaning and re-lubing them, or adding a layer of brake quiet on the back of the pads.
Also, the choice of brake pads can matter. Ceramic pads like Akebono are known to be very quiet (which is to say they tend to resonate at frequencies we can't hear).
I did a quick lookup and it looks like those are ceramic brakes pads and they should be very quiet. Most likely some fresh lube and a thin layer of brake quiet on the back of the pads would shut them up. But sometimes pads just squeak, especially in reverse, and especially after being parked overnight.
