I've had the rotors and pads replaced on my 2006 Toyota Tacoma Pre-runner and the front brades brakes still squeal when braking lightly. I have switched to the premium pads and rotors. What else can be done? The initial diagnosis was warped rotors which I witnessed on the lathe.

    If you have replaced the pads from the dealer and the rotors are not glazed then please use a compound called Disc Brake Quiet.

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 will have to isolate the pads from the calipers, get so antisqeal compound from a parts store, coat the rear of the pads, give them a light sanding on the friction surface and clean them and rotors with brake clean lubricate all sliding surgaces with a lube like sylglide

While trying to change my pads i noticed my rotors seem loose, also i cant get the brakes to stop grinding, squealing after reassembly.
Shane, rotors may seem loose until wheel is on car and torqued to specification, I recommend you take car in for your brakes to be inspected, estimate and repaired at a good shop. Arrange your appointment time so you can be there and watch how it is done and learn from it. Check the attached links,instruction and guides, Good luck

After a couple visits to our local mechanics for brakes repair of a 2006 chevy siverado short bed reg cab. My rear brakes are the problem first the mechanics changed them out with premium pad then now...
Make sure the mechanic checked the park brake shoes inside the rear rotors, they quite often break away from the lining and get wedged in the rotor, sometimes causing a constant squeal noise. I've also seen the brake pad anti-rattle metal clips become loose and wander in the caliper bracket, they lightly rub against the rotor and cause a squealing noise similar to worn brake pads. They are also very bad for the backing plates rusting out prematurely and rubbing on the inside of the rotor. Other than that he can just try to champher the edges of both front and rear pads to help dissipate the brake dust, from collecting and causing squeak noises.

Rear brakes (driver-side) squeal after replacing rotors and pads
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.

2005 Dodge Durango Front Brake Squeal
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.
