R33 Brake Squeal

[kingtube69]

Hi All,

I have had enough of my squealing brakes! It all started when I got the car, there was a very slight squeal, this then turned into the rear pads being worn out to almost the metal. I promptly changed the pads and machined the rotors. This has been ongoing for a while and I have tried most things to get it to stop now I'm at a loss.

The pads have shims that came with them, the rotors were machined, slides greased with anti seize.

Can anyone assist with what could be causing the issue? It ONLY happens when the brakes are cool. If I bed them in it will stop until the brakes cool down again.

HELP!

If I have missed anything please let me know.

What brake pads?

Try different brake pads. And if you have shims copper grease fresh discs fresh pads then you will have to rebuild the calipers.

Done

They are currently RDA pads but they had Bendix on which were changed as I thought these were the cause. Sounds like the calipers

Have you gone over your brake setup? Everything's tight, no hot spots on the discs? Pads aren't glazing over? You have the retainer spring going on the top of the pads?

2 ways, copper paste on the backing plates or PBR Anti squeal, and make sure you leave the shim they supply on the pads.

Also retension the spring loaded plate that goes over the 2 pins as it pushes the pads down to stop them bouncing around.

Your noise is most likely between the back of the pads and the caliper body contact points including the pistons, its caused by the pads moving at a high frequency and rubbing inside the caliper.

Also make sure you have done at least 500Km to make sure they are bedded in, during bed in expect some noise and dust.

We are RDA agents and sell thousands of their pads yearly without issues if the person fitting them knows what they are doing.

I've had a few checks over it as its an ongoing problem. Discs look fine and I've pulled off the pads and given the surfaces a scuff. Also retainer spring on the top - greased the slides too

I have nickel anti seize, supposed to be higher temp, is this fine? I dont remember if I tried this but it will be my next shot

How tight should the tension be with that spring loaded plate? Mine is TIGHT to say the least.

Thanks for the help guys!
