Brakes still squealing after changing brakes, pads, rotors, and fluid?

It is driving me crazy. The car is a Chrysler Sebring
Brakes still squealing after changing brakes, pads, rotors, and fluid?
Check to make sure the dust shield(s) didn't get bent and rubbing on the rotors.



If it only squeals when you apply the brakes, you may need to install 'anti-squeal' (I don't know the technical term) pieces between the pads and the calipers.



Brake dust can also cause squeaks. Cheap brake pads may create more dust than higher quality ones.

Your new pads should have came with little stick on pads that go on the back of the steel side of the pads (they reduce and mostly eliminate, the squealing of brakes ) .If not you can parchase a small aplication of adhesive that you can coat the steel to caliper side of the pads ,it's an insulator in liquid form just like the stick on ones that come with most pads .

This should stop them from squealing .

If it is not a pad issue you could have sticking sliders the calipers ride on .
lacali, How would you like to permanently fix the problem so you won't do off the deep end?



I hope who ever did your brake job used ceramic brake pads. Semi-metallic or full metallic pads are dirty, squeal like hell and eat-up your brake rotors. I hope the boys didn't use that type of pad. Good, name brake pads (Bendix CQ.3, AC-Delco Hawk and EBC-Red are all ceramic based pads and have anti-vibration shims that are supposed to either snap or glue to the non friction steel back side of each pad. If not here's what to do to stop the racket:



Remove the brake pads and clean them up with CRC Brake Cleaner paying attention that the steel side is really clean. Coat the steel side of each pad with a .090 layer with CRC Brake Quiet. This stuff is a red/orange high temperature silicone that spreads like toothpaste. Let the pads dry for 30 minutes before putting everything back together. The silicone permanently stays flexible and absorbs harmonic vibrations (brake squeal) which is now %26quot;driving you nuts%26quot;. The inexpensive CRC products can be purchased at NAPA, Carquest and Auto Zone.



We've been using these products for six years with excellent
if you did not use the shims behind the pads , you can get noise. also if you do not have lubricated slide points like the area on th pads that are in contact with the caliper NOT the rotor, you can get noise. i would pull it all down and clean every thing and lubricate all of the sliding points. i do not see how replacing the fluid would change a noise potential but it is still not a bad idea given the temperature ranges that it gets up to.
Make sure a pad did not get put in backwards. If that is not it, maybe your calipers or something is stuck to your caliper(s) that is touching the rotors.
