ive finally gotten faster and i guess the brakes generated so much heat that it melted the boots. ive just installed some brake ducting so i am hoping it will help.

how many still run it as is?

should i just rebuild it?

 

My boots melt off within a track event or two. No need to rebuild for the boot.

 

I rebuilt my brake calipers once because I suspected a sticking sliding pin, and the dust boot was burnt off as well, so I figured I'd just rebuild all of it. I tried to get the new dust boot on for about 20 minutes, said "screw it" and put it together and threw it back on the car. That was about a year ago and I haven't had an issue.

 

Forget about it!

 

If you do leave it off be sure and clean the piston off before pushing it back in.

 

You really need a form of compressed air to get the boot over the piston, I don't think it's possible to get it on without or at least I wasn't able to.
I need to do mine again so I'll do a DIY.


Rebuild without boot:
One think to keep in mind if you don't use the boot is to at least use the seal like looking piece of the boot that goes into the caliper (just cut it off the boot).

 

Mine have melted long ago. I just leave it. If it ever starts sticking, then I will address the issue.

 

I was able to rebuild the caliper without any compressed air, but it was a sincere PITA. Worse, the dust boots tore after a few track days, and never bothered to rebuild them. Never had any issues. I do bleed the brake fluid before every track day, though.

 

I posted in another forum about my cooked dust boots and they thought i was crazy, trying to say i tore them performing maintinence and R-R. This post is like a track day support group.

 

Did they ask if you were Dear Serious?
