Replying to: pcjd388 (Jun 10, 2008 6:04 pm) Your problem is beyond my pay grade. But I'll ask a couple of questions. Did you put the replacement pads on yourself? Were they semimetalic or ceramic? Were they the inexpensive version? Did you use a rubbery coating on the back of the metal plate for the pad that dries before you assemble the brakes--the coating can stop some vibration that the pads might do. But under heavy braking they shouldn't have a squeal.   Your calipers wouldn't cause that. It's something about the contact of the pads and the rotors.   I know the replacement pads I put on my car had the front and back edges beveled at a 45 degree angle that was to keep them quieter... That's why I was tactfully asking if your pads might have been very inexpensive and didn't have that when they should. Or they might be too hard.   Are you having any other symptoms that might make you think the calipers are a problem? Dragging? Pulling? Overheating? Pulsating?

Replying to: imidazol97 (Jun 10, 2008 7:03 pm) yes, the brake pads were the least expensive that you can buy in the semi-metallic kind. No, I did not this time put the coating on the back of the brake pads. yes, my brakes also had the bevelled edges on them also. The only reason I think that it could be my calipers is the brakes pulsate upon stopping like that calipers are bad, so plz let me know what you think...I did put the brakes on myself as I always do adn never had a problem like this...I did have a baretta that had the same problem one time and when I put new calipers on it after trying everyhting, the problem went away but since they cost so much for this car, I want to be sure before i do go buy them Replies to this message: imidazol97 (Jun 11, 2008 10:00 am)

Replying to: pcjd388 (Jun 11, 2008 7:07 am) I can't hear the noise you are hearing so I can't distinguish between the sound of pads lightly rubbing on the rotor (normal) as you drive. With light application is usually when I'd hear the vibration of metal backing plates moving against their metal holders in the caliper.   You'll have to decide what you're hearing. I'd suggest having someone drive the car slowlypast you in a parking lot to listen for the noise from outside.   Calipers were only $30 each at AdvanceAuto recently for my 98. I broke a bleeder screw and just went ahead and replaced both rather than having the bleeder dug out or doing it myself with screw extractors.
