Brake caliper dust seal...lube?
Just about to fit a dust seal to a caliper...and wondered if I need to put any lube inside?
I know you can get red grease that is rubber and brake freindly...but I don't have any
so my choices are limited to what I have already
copperslip...not sure if this will swell the rubber?
LM grease...again unsure
Perhaps a drizzle of brake fluid?
or nothing, just put them on dry making sure the piston is dry when I put it on
Done some searching and not found an answer
Tackling this today and will keep an eye on the forum for words of wisdom :-)
Regards
Rob

usually no lube is required, just assemble with clean brake fluid

I always put a light smear of red brake grease on stuff like that . I don't like using brake fluid because it attracts moisture and promotes
corrosion.
Cheers

Absolutely, you don't want brake fluid anywhere past the seal.

Clean & dry, I would think.
Any grease will surely attract and hold muck and grit and make matters worse.

Cheers chaps
Have gone with the "dry method"
All gone well, but of course its pi$$ing down now its done :-(
(sorry its my fault)
As long as it keeps the moisture and cack out I guess it should be OK for another 30 odd years

Red Rubber grease is the only grease or lubricant apart from brake fluid that can safely be used anywhere near hydraulic rubbers and surfaces.
White brake grease is only for the mechanical parts of a brake system only ---- ie self-adjusters and pivots.
Even a tiny pinprick of WD40 will destroy brake rubbers over time.
