i was changing my rear pads on my 93.5 today and when i was turning and pushing the piston back into the caliper, i accidentally put a tear in that rubber boot thing surrounding the piston. is this going to cause future problems? or anything?
It will lead to dirt and grime getting into the piston, which will lead to scoring the mating surfaces and eventually you will need to replace the pistion. I dont know if you can just purchase the piston boot thingy, you may want to contact Joe at www.infinitipartsusa.com and find out.
I can attest to future brake failure with the torn dust boot.
The Corolla I had years ago had the caliper freeze up because of rust building up in the bore and on the brake piston.
I would expect someone would sell a brake rebuild kit with the boot, piston seal, bleed valve, etc. That's what I did on the Corolla, honed it out and put in new seals. Midas wanted $500 for all new brakes, they would NOT rebuild a brake only SELL you rebuilt ones.
