I use this, you don't need much just some in the piston contact area and a small amount where the outer pad contact the caliper frame.
This is available almost everywhere, Permatex has a blue version in a spray can or liquid packets, its a poly membrane like the CRC. Unlike the red spray can it will glue the shim to the caliper or piston and loosen it from the pad.
A word about doing the brakes on these cars you may already know but for others..
Make sure the caliper is fully seated then use the 7mm allen socket to start the pin bolts by hand, make sure they are threading before using a ratchet.
The threads are in the steering knuckle and not very strong, they are
very easily stripped. They require a 9 x 1.25 mm thread insert 10 mm long. This is not a common size. I have done quite a few brake jobs on these where a previously installed long helicoil has come out with the pin. I keep a stock of the correct ones and real solid inserts just in case.
If it had a helicoil a correct length one must be used, the threaded solid insert has different external threads.
Tighten it to spec or just tight if no torque wrench, do not over tighten, even if it doesn't strip this time you can weaken the threads and the next time it may strip.
Apply it like this.
Not like this.

Thanks for the tip. I was always extra careful not to strip the hex heads, but I'll use my torque wrench when I tighten them next time. You wouldn't happen to know the torque spec, would you?
