I have the 6pot wilwoods, and there's no dust boots to protect the seals from brake dust. Someone suggesting using some high temp silicone over the gaps between the pistons and calipers to keep dust out of there.

Anyone else tried this? Used anything that can withstand the temps? I'd hate for it to attract more brake dust or trap moisture in there. It looks like at least one of them has weeped a bit past the seal.

piston has to move out and in freely that would prevent it. I have had no boots on my vehicles even my truck the burn off. I have had the Wilwoods on for 3000 track miles.

i do get in there with compressed air after track weekends and blow all that garbage out. doesn't help prevent the searing dust, but at least doesn't allow it to sit there. Just make sure you cover your nose/mouth/eyes cause that sh*t goes everywhere.

I was thinking more of a silicone grease, not silicone putty.

I just rebuilt mine today and they were fine seals were slightly rough on the exposed side. They had many track miles on them. They never leaked either. I would no be to concerned.

I had Wilwoods on my car for several years on track and in the salt in the winter. I asked Wilwood about effects and their comment was that I should clean the pistons before shoving them back into the bores at pad changes. All the dirt track guys run Dynalites with no boots. If it works under those conditions it will work anywhere. The pistons were fairly easy to clean up. I was able to grab them with a piece of rubber (for opening jars) and rotate them so I could clean all the way around.

Yes, that is a step frequently overlooked when changing pads on any caliper. Clean the exposed piston as best as possible and then generously wet them with brake fluid. Then push the pistons back into the caliper.
