Replaced pads, Rotors on all four wheels. getting right rear brake squeal at the initial use of brakes at slow (traffic, parking lot) speeds. Have tied removal and cleaning, sanding pads, after market squeal inhibitors, etc. Seems only to be affecting Right Rear.

it just sounds like a poor quality job...the proper way to do a brake job is a high quality set of front pads such as a bendix or raybestes gold line pads,, then have the front brake rotors machined an a amco brake lathe or even better a on the car brake lathe. make sure all brake caliper hardware is properly cleaned an lubercated or replaced with new hardware....then have the rear brakes adjusted( adjust only if ur car has rear drum brakes...rear disc brakes r selfadjusting
Before servicing the vehicle, refer to the precautions in the beginning of this section.
Remove or disconnect the following:
Clip, 2 caliper pins, the anti-rattle spring then remove the 2 brake pads and the 4 anti-squeal shims
CAUTION Only replace brake pads on 1 side of the vehicle at a time. Failure to use this procedure could cause the caliper pistons on the opposite side of the vehicle to pop out requiring the reconditioning or replacement of the brake caliper.
Remove a small amount of brake fluid from the master cylinder.
Install a used brake pad into the caliper and compress the caliper pistons.
Apply disc brake grease to both sides of the inner anti-squeal shims.
Install or connect the following:
Anti-squeal shims to the new brake pads NOTE: When replacing worn pads, the anti-squeal shims must be replaced together with the pads.
2 brake pads
Anti-rattle spring and the 2 caliper pins
Depress the brake pedal several times to seat the brake pads.
Check the brake fluid level and top off as needed.
Are the leading edges on the brake pads bevelled at an angle or are they flat on the brake rotors? There seems to be a problem with Japanese brake rotors (something about the harmonics) and they will sometimes squeal (even with new brake rotors and pads) if the leading edges on the brake pads are not bevelled at an angle. Most of the auto repair shops that I have worked at will only install bevelled edge brake pads on foreign vehicles, especially if they are Japanese imports. If the brake pads do have the edges bevelled then most likely dust has found its way between the brake pad and the brake rotor, and brake dust contamination is the #1 reason for a brake squeal come-back, and that is why a good repair facility will always clean the entire brake assembly including the backing plate for the brake rotor. Also, the brake caliper guides should be able to slide freely in and out of the brake caliper but they should not be sloppy either, and the brake caliper guides should be lubricated with a synthetic brake caliper grease only. The caliper guides should be able to slide freely in the brake caliper and if they do not the brake will not properly release.
If the brake calipers have phenolic (plastic) brake pistons then get rid of them for brake calipers with metal brake pistons.
Here is an image of the two different brake pad designs.
You, Probably will, Brake Squeal is NOT a new problem.
Disc brake's have been Squealing since, They, became
factory installed on chevrolet in 1971. Before, that they,
were a option. In 72 they even had a bulleton how, to
FIX it. And, no it didn't work.
With That said, Any time you replace Brake pads you,
should always re-surface the Rotors.
Why? First you may start to notice a pulsation as the
pads ware (sometimes! ) The best way to avoid, brake
squeal is to manchine the Rotors put, the blue membrain
sealent on the back side of the pads. And hope that works!!
Some brakes Pads squeal JUST SQUEAL??
You, Could do the same Brake job the same as you did
this one and, they may NOT Squeal.WHY, I WISH I NEW. They
sell all types of STUFF to stop Brake noice DON'T waste your $$.
you need to grease the metal clips at the top and bottom of the pads (dont get grease on the rotor or pad though) and also spray some "disc brake quiet" on the back of the pads. it comes in a red can and the spray that comes out is like sticky red paint. do those 2 things and the squeals will be gone.
Pads will reproduce sound just like a needle on a phonograph. Hard linings will accentuate this. Have the rotors re-surfaced and finished with a non-directional pattern(I make a quick pass with a D/A sander over surfaces while still on the lathe) Generally this will help.
Did you buy factory pads or get cheap aftermarket pads? If aftermarket did you get the ceramic? The cheap aftermarket ones tend to squeal pretty bad. Like the last comment on here, you should have your rotors turned whenever you change the pads.
