V8 Beast Posted July 6, 2009 Report Share Posted July 6, 2009 On Speedracers.. oh I mean my wifes car her brakes squeal. Its not like the normal noise you get from brake dust.. its more like the squeak of 2 smooth surfaces rubbing together. Brakes have been changed and have over 95% pad on them. We changed them to see if that was what was causing the noise and obviously it wasnt. When I cleaned them with brake cleaner I noticed it did get better but still kind of grabbed and sqeaked as she came to a complete stop. Not sure if there is a component of the braking system that needs oiled.... Or do you think I should I rub the pads on the sidewalk to stop the noise?

Cordell Posted July 6, 2009 Report Share Posted July 6, 2009 What kind of pads did you buy? Did you turn or replace the rotors? Does the pedal feel normal? If there was a problem the pedal might feel funny, cheaper pads can do stupid shit like this, or old rotor surface. If the pedal feels good, I'd turn the rotors and scuff up the pads (not on the sidewalk use sandpaper). Quote Link to comment Share on other sites More sharing options...

Rotors are 6 years old and speedracer stops harder than she accelerates. Time to replace those too Quote Link to comment Share on other sites More sharing options...

Time to replace those too What do the rotors look like? Age doesn't neccesitate replacement, just warpage, grooves, rust pitting, and of course thickness.

Guest tbutera2112 Posted July 6, 2009 Report Share Posted July 6, 2009 dumb question, but did you use grease on the back of the pads? Quote Link to comment Share on other sites More sharing options...
twistedfocus1647545489 Posted July 6, 2009 Report Share Posted July 6, 2009 Smear grease on the front of the pads. Quiets them right down... Seriously though, if that car uses the type of caliper that has slider pins/bolts (and it likely does) you need to grease them with a good high temp grease now and then. At least each time you put new pads on, or they can get gummed up and may not slide on the pins freely causing them to drag lightly. Quote Link to comment Share on other sites More sharing options...
Guest Removed Posted July 6, 2009 Report Share Posted July 6, 2009 moly lube on metal to metal contact surface's. most brake noise is a vibration, of metal to metal contact.. and those cheap ass 10 pads just plain make noise. and rotor surface has to be correct aswell Quote Link to comment Share on other sites More sharing options...
Dave1647545494 Posted July 8, 2009 Report Share Posted July 8, 2009 this sounds all ghetto, but take the pad off and put a a couple of pieces of duct tape on the back, or some of that orange goo if your not a cheapass like me. it should quiet down. you also need to lube the pads where they contact the hardware and make sure the slide pins are free if it doesn't shake I woudn't worry about the rotors much for a squeal Quote Link to comment Share on other sites More sharing options...

AJ Posted July 8, 2009 Report Share Posted July 8, 2009 but really i would try and burnish them in again. Here are the GM instructions for burnishing the brakes: Burnishing Pads and Rotors Caution Road test a vehicle under safe conditions and while obeying all traffic laws. Do not attempt any maneuvers that could jeopardize vehicle control. Failure to adhere to these precautions could lead to serious personal injury and vehicle damage. Caution Refer to Brake Dust Caution in Cautions and Notices. Burnishing the brake pads and brake rotors is necessary in order to ensure that the braking surfaces are properly prepared after service has been performed on the disc brake system. This procedure should be performed whenever the disc brake rotors have been refinished or replaced, and/or whenever the disc brake pads have been replaced. Select a smooth road with little or no traffic. Accelerate the vehicle to 48 km/h (30 mph). Important Use care to avoid overheating the brakes while performing this step. Using moderate to firm pressure, apply the brakes to bring the vehicle to a stop. Do not allow the brakes to lock. Repeat steps 2 and 3 until approximately 20 stops have been completed. Allow sufficient cooling periods between stops in order to properly burnish the brake pads and rotors. Quote Link to comment Share on other sites More sharing options...
