Does anyone know what the white grease used in rebuilding HD calipers is? It looks like white lithium grease but that’s just a guess. I used up all my factory HD caliper piston grease that I had from HD rebuild kits & the Dennis Kirk rebuild kits I just bought don’t have it included as the HD kits do. I’m using Dot 5 silicone base brake fluid so I need to use the right grease. Thanks for any good info.

 

I have always just used the brake fluid as a lube to put together. I have been building calipers since the 70's

 

^^This. Unless you are talking about the caliper slides. Automotive caliper slide grease is fine for that. Never any grease internally. Lube internals with fresh brake fluid as gdishman stated.

 

Believe it or not, it is piston caliper grease. Do not use white lithium grease. Get the proper type be it for the older DOT5 or the DOT4 now used. It allows the piston to come back with just that light leaf spring. It's in Honda cars now also. (I just rebuilt a 2005 CRV and it was still in and around the piston) Just using brake fluid will no longer work.

Go to the Harley Davidson site and bring up brake pads or caliper repair kit and grab the PDF installation file and read it on how important it is..

 

Interesting. I'm going to read up on that. Thanks.

 

What I have is silicone. Marked GE piston lube. Big commercial Green tube. Interesting but my service manual says do not use brake fluid for lubrication. Will result in increase lever travel. I use it on any other rubber part like the sliders on car brake system. I have some heavy copper base anti-seize I dab on any metal to metal slide points and a film on the back of pads or the tabs on shoes that rub on backing plates.
