Brakes squeaky after change. Bearings?

So I change my front brake pads on my 2004 rav4 about 3 months ago. After that it was super squeaky which I thought was them bedding in. Today I changed the rotors and it still squawks just the same. Even bedded them in again. So a couple people say check the bearings. Is changing the bearings a do it yourself job or service only?


The current squeak changes pitches and is not constant. It happens going strait or turning and does not do it more or less with either. Happens only at low speeds like less than 35. I don't understand what is up. There is no grease on the rotors or pad surface, everything looks to be right. Anyone have some ideas?

Pads need to break in, plus there's a lubricant or something you're supposed to apply to the rotors

You should never lubricate the rotors > reduces friction > and braking relies on friction.

My front brakes squeeked after dealer replaced front rotors and pads. The reason was that they forgot to install anti squeel shims. In your case it might be that if you are using your old shims they are too corroded to work properly.

Btw - the shims should be greased according to the service manual - but never rotors.

Hi your front pads should have anti squal shims in they are metals plates the same shape as the pad .if they are not there they may still be stuck to old pads you took off !

Front wheel bearing do not normally squeal its more like a rumble but they are "press out " bearings and are one unit per side not split in to two tapered ok


Hope this helps

Ok so the shims are difinatly still there, however one is in two pieces. Anyone think that's the culprit and are these shims something that is readily available? Like do I have to go to Toyota to get them or are whatever the shop has laying around good enough.

I used the wrong term, should not have said lubricate. There is a chemical that is applied to make sure they grab correctly. Its on my invoice

Hi yes you can get an after market set of shims but please do not just put anything in you will give yourself much more grief if you do that !

yes the broken shim will vibrate as you apply the brakes and that will most likely be the cause of the squeal

Have you used copper grease when you installed the new pads to help them work right and with any after market pads i always give them a little file to take off the paint on them before fitting so they can slide better when fitted .

Please always remember that when you use brakes everything gets very hot so it expands with the heat if your pads are really tight when you fit them once they expand with heat they get even tighter so then the grease helps but use copper grease sparingly !
