    New Rear Brake Pads - Backing Plate / Grease Question ?

    So I'm putting new rotors and pads on the rear.

    I have a set of stock Brembo pads (came with backing plates, and a copper looking grease)

    Where do I apply this grease ?

    ----------

    Also meant to say, yes I did check the FAQ for this simple question, but did not see anything specific.

    Thanks.

    You put the grease on the back side of the pad then place the metal shim over it. Do NOT put grease on the wear surfaces.

    Thanks, ya I knew not to put slippery grease on the friction surface. LOL.

    Nothing on the other side of the shim ? Seems everywhere I read online they say to put it on the edges... but I don't see how it would ever stay on the edges for very long.

    Re: New Rear Brake Pads - Backing Plate / Grease Question ?

    Its used for anti-resonance, and really is only effective, IMO, between the pad back and the shim. I too have seen procedures call for something to be applied between the shim and caliper piston face on other cars, but have never done that because its a mess, attracts and holds more dust, dirt, and grime. I personally use the bright orange CRC discbrakequiet goop. If given time to set, it cures to more of a rubbery substance and works fine for street pad temp ranges. I used it the first time I loaded a set of track pads for an HDPE out of habbit and it didn't last long

    Thanks for all the input. I didn't know how critical this grease was.

    I'll admit, I had already put the pads on last night, and I did spread the grease between the shim and pad back. Just wanted to make sure I did it right. Haven't got it all the way back together cause I had to order new hardware; one of the pin retainers was broke.

    The crc disc brake goop keeps the pads quiet by essentially gluing them in place and the grease keeps the pads from squealing as they move around.

    No, nothing on the other side, that is it, just did a brake job on the 'V' with stock pads - no squeals and absolutely wonderful braking power!

    What do you guys do with pads that come with the shims already adhered to the back of the pads? Do you find that whatever they use to stick the shims on there provides the anti-squeal effect?

    Both the Raybestos front pads and the Stoptech rear pads I'm using now have shims already on them. I've been putting a little bit of grease on the outside of the shim, just where the pistons make contact - trying to use as little as possible to avoid the mess that was referred to earlier.

    I have not done any brake work on my V yet, but all of the Hawk street pads I used on my legacies, both OEM and brembo's calipers, had a shim bonded to the pad. I modified the OEM shim to fit the pad and prepped the surface between as usual. The pistons had to be fully compressed to fit the extra material, but my results were better than the one time I ran the pads w/o shims. The shim kept the entire assembly a little more tidy between services.

    Gotta be careful when you start stacking shims. The brakes will expand a little when hot and can start to drag if you get them too tight.

    I also think this is one of the unofficial uses of the CRC. A lot of guys will dab it on the back of a pre-shimed pad and let the CRC essentially glue it into the brake piston so it won't move around. Kinda messy but I can't say that I've seen it cause problems either because it cleans up easily enough...
