I've purchased all new internals (piston and rubber) for my TR3A brake calipurs.
Using the carb cleaner and blowtorch method, I got the pistons out of the old calipurs.
Then we painted the calipurs. Now I'm reassembling, and I'm having some trouble getting the new pistons in...
Here's the trouble: I can't seem to get the rubber boot to stay in the notch cut in the calipur. Once I do get it into the notch, and I start to slide the piston in, it stops about 1/4 inch in (on the inner o-ring, perhaps), and refuses to go any further.
I hesitate to fab up some sort of special tool to fit into my press just to re-install the pistons. Mainly, I don't want to risk gouging the new pistons, or tearing the new o-ring, or worse, destroying the calipur.
Anyone ever done this rebuild before? Any suggestions?
Thanks,
Rob
