Brake Noise - Please Help!

Recommended Posts

Had this problem for a few weeks now - not only is the noise really annoying but so is my wife's complaining!!! It's also getting embarassing.

The brakes are making a squeal noise which stops when the pedal is applied. It is pretty much constant and is a metal-on-metal noise.

The pads and discs are fairly new but are well past the bedding in stage. I've taken the pads out again and applied copper grease to the backs; the callipers seem to be moving freely; there's no stones or anything stuck. I've spent hours stripping them down and putting them back together again.

Has anyone had a similar problem or have any idea what the cause could be??

The car is a 2002 Rav4.

Hello Paul and welcome to the club :thumbsup:

Have you been using the guide from the pinned section at the top of the forum page?

If not, see here:

Just wondering if you have got the wee stainless 'support plates' in correctly as one has a bent tab that acts as a wear indicator by squealing when in contact with the disc.

Hi RB5, and welcome!

Interesting . . . I've had an annoying squeal from my rear discs, which touching the brake pedal will stop. It then resumes.

Noise is a very high-pitched squeal, almost out of hearing range, and there at low road speeds (c.10-15mph). It's not the same as the pad-wear indicator noise.

The rear pads were recently renewed (genuine Toyota) - no squeal before that - and all the s/steel shims and springs are correctly in place and copper-greased. Calipers look free and ok.

The car is a 2002 Rav4.

Have you used all the front anti squeal shims/plates and are they facing the correct way ?

I believe each front pad should have two anti squeal plates between the pad and the calliper.

The inside plate has holes in it, this plate should be covered both sides in a very fine smear of brake grease.

I also coat the interface between the caliper and last anti squal shim with a smeal of grease.

Both plates on every pad have arrows showing correct orientation ?

Ooops answered an old post about front pads earlier !!!

Similar question though re rear brakes, did you use brake grease on the inner shim ?

Also I have found the rear calliper sliding pins are very prone to seize/stick.

It might be an idea to remove the rear callipers and take out the pins which have dust boots at each end and lubricate them.
