Look at your brake caliper dust covers

[986_c6]

I never thought to look at the dust covers. Do you even need them if you track your car and its sole purpose is to keep brake dust away?

I'm not sure about these calipers, but on my Formula Ford the dust seals are left off, since they can melt under race conditions.

I am not sure that I am following your logic. The purpose of the dust covers is to prevent brake dust from entering the brake pistons, making sure the don't seize On the track I create more brake dust that anywhere else. So why would it be a good idea to leave them off on the track?
I am not trying to be a d**ck, I am sure you thought your response through and I am missing something here...

This may not be an issue with Boxster brakes, but the reason they are left off my FF is that they can get too hot, and actually melt, causing the caliper pistons to stick. I think the other theory is that on track they are cleaned regularly, and not subject to the long term neglect that street cars can be subjected to.

I think what you meant by "clean" is the calipers get rebuilt regularly after a few races. There's no way to clean dirt/dust that's trapped between the pistons...

In my case, I just flush them with brake clean when I change pads. A FF isn't terribly hard on brakes.
