I had been using copper grease on the back of the pads, pins and area surrounding it in the calliper (not the calliper seal)

Is silicon grease a good replacement because of its temperature, low interaction with other materials and lubrication performance?

Silicone brake lube(recommended) is what I use and does not deteriorate the rubber boots around the caliper pins or the dust seal around the caliper piston. Also helps to reduce the chance of brake noise. Hope this helps.

those are also my thoughts.

when you say silicon brake lube; is this the same as straight silicon grease?

Bendix Ceramlube is allegedly the mutts nuts. Bought some but lost it before I could try it out.

There's also "Red Rubber Grease", which is red, and ok for rubber.

Well, I don't know exactly if they're the same which is why I just go for the good stuff. I also don't know what products are available to you in the UK. I use a variety of good name products from companies such as:

*Permatex
*3M Company
*Sil-Glyde

Consensus: silicon lube for the caliper pins (prevents swelling of dust boot and is nice and slippery), anti seize for everything else.

Who's consensus? Definitely not mine. Use only brake specific lubricants that are designed for that purpose.

My favorite is:

That's what I use, Silicone Paste on the pins and antiseize on the pad edge contact points. I have some Permatex Purple Ceramic grease that I bought before I knew of the boot swelling issue, so I use that on the backs of pads.

I've been thinking about changing it up though. I find that the ears of the pads and the stainless clips get pretty dirty and gritty with the antiseize. I'm thinking about going dry next time, or maybe even trying a super thin film of Silicone Paste.

GMBoy, I think that's the exact stuff I have on hand. Even though the bottle says it should be perfectly fine, I've heard reports of if causing rubber parts to swell.

This is one of those topics that everyone has a differing opinion on....

The Superlube is good stuff but it might be a little thin. I use the Sylglide made for brake use.

I agree and excellent point. I didn't mean to sound harsh. I have not heard of the swelling issue with the purple lube...I may go back to the dark green style.

That grease is not designed for the high temps of a brake system. It is probably already melted away.

3M silicone paste has a working temperature of -40F to 400F, Dow 111 is also 400F, and SilGlyde is 425F.

The Superlube silicone lists a working temp. of -40 to 500F

Oh Wow! I didn't realize that. I think I still prefer a dedicated brake lube but that sure sounds like it would be a viable option.
