i had same issues with my s2k ball joint boot. i used fiber glass heat wrap and it worked good. might do the same thing here. those boots are cheap enough to replace every season if need to though, they were $15 + shipping for the set.

i picked up these RB stainless pistons and seals from my sponsor.
ss pistons - http://www.shop.motorsportsperforman...per-BM-41P.htm
seals - http://www.shop.motorsportsperforman...rs-BM-41BS.htm
OE 46mm pistons = 0.18 lbs, RB SS = 0.225 lbs; .045 difference
OE 40mm pistons = 0.14 lbs, RB SS = 0.19 lbs; .05 difference
that's a total of 0.19 lbs (1/5 lbs) difference for all four pistons for one caliper.


oem dust seals all burned and cracked

opening up the calipers

caliper split in half

oem pistons next to stainless pistons

use compress air at the bride port and a used pad underneath to prevent one piston from coming out complete and not allow the other one to come out.

remove the oem dust seals

remove oem piston seals

clean out caliper

new stainless pistons and dust seals ready to go in

lubricate the pistons with some brake fluid so they slid in easy

all four pistons are in and ready for reassemble
