Brake calliper assembly lube
« on: December 22, 2017, 10:43:47 pm »
The question of how to lube brake pistons and seals when reassembling them seems to come up periodically.  Using brake fluid works, but leaves a bit of brake fluid on the exterior parts.  Not really good considering the affinity of brake fluid for moisture.

While wandering around the net looking for a brake assembly lubericant, I found this stuff:

 It's called Red Rubber Grease, made by Castrol.  Looks like it might be a good solution, but I don't have any knowledge of how well it actually works. 

Has anyone used this stuff?

Remember, much of what you see on-line is wrong or misguided, your task is to filter that out!

      The ONLY thing I would use Brake/Caliper grease on....

Would be the slider pins on some AUTO brake systems and the contact points on the,  Brake Shoes/Calipers!

As far as anything around the boot piston covers....Brake fluid only!

ANY amount of a petrol based fluid in the brake system and you have big problems!

I use CRC Synthetic Brake Caliper Grease!

My opinion! ;D

I bought some high dollar rebuild kits with stainless steel pistons and they had a little container of red grease that they advised using on the seals.  I looked at the link you posted.  Looks like what you need.  Never heard of the stuff before buying kits from Brake Crafters.

I use RRG on car and bike brake sliders, piston dust seals etc. and Ceratec brake grease on the backs of pads, metal to metal sliders.
There is a guy on ebay UK that sells 2" round tins of greases, RRG, zinc and aluminium stuff for stainless steel, I bought a few which cover every combo I'll see
