Squeaking brakes

BraveDonut

I have the same problem and picked up some copper grease this morning.
I see from the link above that you actually apply it to the back of the pads.
However, I fail to see how that stops the squeaking.

Is it just that it stops the pad from vibrating in the bracket?

Copper grease is the solution. Be careful only to get it on the back of the pads, no where near the front of the pads or discs. Not sure what type the pistons are.

If you get a small amount on the front don't worry, it'll burn off.

Or stick two layers of duct tape on the back of the pads. The tape will absorb the vibrations.

The rear brakes on a 00 Avensis are drums and shoes not disks and pads.

You can still try and solve using the copper grease by taking off the drums (not the easiest on the Avensis if there is a lip on the drum!), removing the shoes and putting a tiny amount of copper grease on the parts of the shoes in contact with the hydraulic piston, the holding slots on the opposite side of the shoe, and the brake adjusters. You should also apply a tiny amount to the inside plate, against which the shoes are held by a spring. You will spot the small areas of contact.

Bear in mind that the squeal could also be caused by the glaze on the linings of the shoes or a seized automatic adjuster, and if you suspect either is the case, the shoes would be best to be replaced.

That could get smelly...

I don't think duct tape would take the pressure applied to a brake pad, nor the vibration and heat, very well!

Not for long, it won't!!

Ok, some more sources for the doubters.

He taught me that the “Sure-Fire” way to eliminate disk-brake squeal was to slap a piece of high quality “Duct-Tape” on the back of each pad before mounting them inside the caliper. Since that time, I have used that technique on well over 100 cars (through the mid 1980’s) and have never had anybody complain about noisy brakes again.

Worked like a charm. I used 2 layers of duct tape on all pads, and not a sound...

By sure-fire you mean it's sure to catch fire?

biko

I wouldn't recommend it for any type of performance driving.

I applied copper grease to the backs of the brake pads, but the squeaking still seems to be there. Any other ideas on ways to reduce this?
Thanks,
