Default Quick question - STi Brembo caliper piston dust boot

I was swapping out brake pads tonight, and found that the outer dust boots are cracked. Each of the outer piston boots has several radial cracks. I was researching the dust boots on here and it sounds like these only serve to prevent dust and dirt from getting to piston seal. So my question is... I will be ok to finish out the race season (1 more weekend, 3 days) before changing them correct?

I know they should be replaced. I have a feeling that they have been like that for awhile and I just now noticed it. This is something I would like to wait and tackle during the offseason if possible.

Thanks for the help

Cracked, or torn? One more day shouldn't be a deal breaker for cracked. Personally, I'd chance it with torn...

Blame PIR.

Have fun.

^^ Of course!! I blame almost everything on Portland in general

They appear to be just cracks, but they could be all the way through. Right at the where the boot folds on itself.

Remember, racing calipers do not have those dust shields. They'd cook, but the brakes work just fine for hours and hours of abuse.

Replace them at your leasure.

That is exactly what I thought I had been reading. Just wanted to verify.

Thanks for the help.

I thought I read that boots were only $5 ea... I may wind up swapping to the StopTech BBK before the start of next season anyway, but not in the cards yet.
