Title: What grease for rear brake caliper rebuild?
Post by: Darryl on January 29, 2012, 01:47:23 PM
I have the rear brakes of the Alfettta in pieces and they have cleaned up ok - but before I put back together with new seals I need to re-lube the handbrake/adjuster mechanism inside the calipers. What should I use? I'm concerned that a conventional grease will be bad for the rubber seals and won't be brake fluid compatible, while rubber grease isn't high temp... Whats the answer? Maybe Bendix brake lube?

I think that you have answered your own question, normal grease will ruin seals, and rubber grease is not high temperature, i would use the rubber grease everytime, but it seems there are different grades of rubber greases, i have used different types, the thickest is Castrol in the small tubs, and it is colored crimson, is in one of those tubs you buy from Repco for about $10, Bendix brake lube?, never heard of it, it might be worth a go, Colin.

Thanks Col,
I didn't know about the different grades of rubber grease - will grab some of the Castrol stuff. I only had some thin PBR rubber grease.

Its not like its lubricating anything that needs "serious" lubrication - so long as there is something oily left in there it should be enough to protect the parts from corrosion and stop it seizing... And hopefully the inside part of the caliper doesn't get that hot that it "drops" anyway.

I didn't know about the different grades of grease, you just buy it and thats it, i have a tube of 'Patons Brake Replacements', that is nearly as old as me and its a bit runny, the newer Castrol crimson brake grease is thicker and is great for holding things in place when assembling, Colin.
