Squeaking Rear Brake

[Duff]

Hey All I need some advice on how to get reid of a squeaking rwar brake. I had my reap pads changed at my last service and now they are squeaking. Any suggestions on how I can stop the noise.

[Desmo]

Take the pads out, lightly buff the faces and leading edges, then reinstall them with a very thin coat of copper grease on the piston side only.
DO NOT get any on the friction side or the brake rotor.

RTV gasket maker works well on the back of the pads too if you've got any of that handy.

[Desmo]

um, no.
That'll dry solid, you want a bit of movement between the pistons and pads.

[Jonchilds]

From experience, the Red RTV sealant has always remained flexible, atleast over a period of 6-12 months.
It's basically rubber with a bit of acetic acid added to make it viscose instead of solid.

[Desmo]

Yeah, but it's wrong.

[Jonchilds]

It works.

Meh, I'm not gonna argue.

This is one of those rare occasions where I agree completely with Desmo. Onya Jim.

Shmeh.

Some of the the stop-squeal pastes you can buy from Auto1 or Repco is basically an RTV product, so I don't see the difference.
I've certainly seen mechanics use the high temp RTV on pads for a car before as it stops the pads sticking against the discs when the pistons retract.

Take out the pads and sand them to give a new surface and clear all the dust and crap from the rear caliper, and make sure all bolts are at a suitable torque. If this fails get used to it or use the from brakes more.
