As I pour over the OEM parts schematics I don't see any brake boots, boots to keep out dust and water that rusts the caliper pistons. Older bikes had expanding rubber piston covers but they seem to have been discontinued. $$$ generator?
If you're one who rides only in fair weather you won't need it, but I ride 24/365, sun, rain or snow.
Last brake job I tried slathering on Ultimate Silicone Brake Lube but that's only covers the 'Wee-Lit'l Bit' what sticks out.
My next step is finding a caliper cover but that'll only retain heat, so not good.
This BikeGyver is running out of ideas, anyone have suggestions or crossover cage parts?
Caliper brake boots? (not seals)

Re: Brake boots? (not seals)
Thinking of possible parts and doodling. . . .
It's not a perfect seal but better than nothing.
This takes up space between caliper and brake pad, might be difficult slipping said caliper back on the rotor.
The new pads I get are fairly snug on the rotor but pads can be sanded a bit to fit.

Re: Caliper brake boots? (not seals)
As I understand what you are saying, you are looking for a cover for the brake pistons in the caliber. This cover would go between the caliber and the actual brake pad and cover the piston? I have to be honest, I have never seen this on any disc brake whether car or bike.. I have a 1981 Honda bike in my garage and it does NOT have such a thing.
I did replace the pistons a few years ago as part of a total brake rebuild. Cost was minimal, I think the pads cost about the same as the pistons but then you only replace them after years or riding and use.
But the concept sounds interesting!

YUP, keep the pistons covered as they emerge.harvey01 wrote:As I understand what you are saying, you are looking for a cover for the brake pistons in the caliber.

I don't believe it needs a perfect seal just keep water off. Condensation will seep in and can't stop that but if I can slow it down all the better. I live 1 mile from Lake Michigan = humidity.
Maybe it was my XS1100 had caliper boots, too many decades gone by.
The only other thought is coat the pistons with gold via electrolysis.
Got to find a donor ring, oh HONEY....
