With R-comp tires and track pads, the stock front caliper piston dust boot is toast after one track day (even with brake vents). Brakes are fine after 4 days, but I get concerned about road crap getting baked onto the piston, compromising the seal or causing the piston to hang up. I'm thinking an annual rebuild (say 8-10 track days) to clean up the pistons and replace the seals is a good preventative maintenance interval. What do y'all think...unnecessarily frequent or not often enough?

 

I have no idea, but I'm here because I'm curious to know as well. I'm just beginning to track my car (92k miles on it, just getting started), and will probably shoot for 7+ track weekends a year plus autox's, and have new rotors/ss lines/track pads on the way. I have never rebuilt the calipers, but I'm thinking I'll need to do it soon before next season.

 

I went through four sets of calipers is 9 track days. I finally put some brake ducting in. Hopefully, I won't have the same problem this season.

 

RSXLNT, do you mean "four sets of pads"? I wouldn't think rebuilding calipers 4 times in 9 days is normal for even hard track use.

 

Somebody please tell me there is an easy fix, or better part avail for this. I too just started using XP10 brake pads in the front and those seals/boots are history. I plan to track the car 2 times a month and hope this is not routine.

 

Greg W: What are brake "vents"? Do you mean ducts that run all the way to the dust-shield?

 

miamirice, you can try brake vents, but my (and others') experience is that the front piston dust boot burns up pretty quick. The OEM caliper rebuild kit has a replacement, but it too burns up with hard track use.

vjarnot, I'm referring to the ducting from the bumper opening (cut into the bumper fake opening on either side of the grill) to the dust shield.

 

sounds like you need to upgrade to Accord calipers
8 track days on mine so far and the seal still look new

hondaf1, if I browsed your post (great job!!!) correct, the upgrade would be ~$800 (2xcalipers plus 2xRB slotted rotors). Benefits (other then better brake bias with R-comp tires) are longer pad life, rotor life, and time between rebuilds (due to piston boot failure). Downsides are added unsprung weight (though lower rotating weight) and a lighter wallet (initial plus new rotors every ~25 days).

Does this sound right?

 

And to further the thread-jack, how much are the RB rotors when you've already got the hats?
