Help with brake squealing
I changed the brakes in Kendra'* car today because I wanted the RSM'* on my car. I put a set of turned rotors on and some new bendix OE semi-metallics and the car brakes fine however i get a bit of a squeal under hard braking. I understand there is a anti-squal lube or something you can get...but the question is where do you apply it?

Apply the goop behind the pad. Between the caliper piston face and pad subplate. And it may take a few days to reseat the pads to the rotor face.
The squeal is caused by the pad shifting slightly with respect to the caliper piston.

If it'* on her 2000, I would think you need to lube where the pads seat in the stainless steel shims on each end of the caliper bracket. Either use a high temperature grease designed for such uses, or use di-electric silicone grease.
Not sure if you saw in your case but those stainless steel shims accumulate a lot of dust that eventually gets baked on. If you didn't replace them, then you need to clean them thoroughly and then lube them. As for the shims, there is no part number from GM though I think they come with the Raybestos pads.
Cheers,

Yea I got a set with the raybestos, but i reused the old ones when I did her brakes. Di-eletric in the shims where the pads sit both inboard and outboard?

Use a very light coating of grease on the caliper bracket first, just enough to say there is a thin film, then slide the shim in place. Then use something like a small paint brush to coat the ends of the pads and the shims. Be carefull not to use too much because it will build up on the rotor side as you slide the pads in. Once both pads are inserted, use your brush again to just cover over the pad end and the shim.
You can use a little grease against the piston but I think the QuietStops come with a black paper pad on the back side so you usually don't get noise from the piston against the pad.
Cheers,
