Caliper rebuild

[126coupe]

In the 101 projects book it says to use silicon grease to assemble pistons and seals. Is this the dow corning 111 I use on oil return tube o rings and all the engine o rings??

No. Caliper ass'y grease is sold as such at your FLAPS.

Edit (so as to not bump this): Some reading;

"Clear Dow 111 Silicone (the most commonly used silicone brake lubricant) has a working temperature range of -40 to +400ºF and tends to loose it's paste consistency above that. It is primarily used for lubricating plastic and rubber components (not metal to metal). Above its volatilizing temperature, it tends to rapidly decompose... leaving a silica (sand/grit) residue on surfaces it's applied to. Even when Silicone is mixed with other products, fillers or solids, the limited temperature range and contamination factors are still a big problem.

Information taken from: Dow Corning Tech Sheets, Raybestos Lab/Testing Reports, Dow Corning Brochures, SAE Symposium Papers, Wagner Tech Brochure and Various Technical Articles published from 1998 through the present."

Not to rock the boat, but I usually look for something designed specifically for the job at hand. That may or may not be the case with what I buy labled "Disc brake caliper lube." However, IMHO (especially under the umbrella of Warren's infinite wisdom), a synthetic lube such as Permetex Ultra Disc Brake Caliper Lube, offers a higher temp rating and a more catagorie specific formula.

I appologize for being so curt in my in my original reply at the top of this post.

Minkoff,

Absolutely!!!

Yes, any of the common Dow Corning silicone greases, i.e., 4, 111, or 112 ... work perfectly when rebuilding calipers and master cylinders! I have been using Dow Corning Silicone Grease for that purpose since 1969, and never had a single problem!

Thanks early s man! I kinda thought that since the Dow 111 holds up to heat and does not "fall off" This is the stuff that Bruce Andersons book reccommends for engine assembly I think Dempseys book recommends it too!

This is the stuff Dow Corning 111

yes, that is great stuff. to bad i dont have any, i got rejected at GRAINGER because i didnt have a business account. sorta like the first time i tried to by a hefner magazine when i was twelve. i used silglide recommended in the tech article. way more viscous, but it worked ok.

just finished the fronts few minutes ago. EYE PROTECTION is a must. (dont ask)
