I tore the caliper apart that I'm planning to use on the racer. It worked fine, but I felt I should check everything out anyways, considering I need to trust it at high speeds. I pulled out the 2 allen head pins and noticed there's three grooves on each one. Only one pin had 2 o-rings on it, the other had none. I'm assuming the rest of the o-rings disintegrated over time. Can anyone tell me the correct number of o-rings for each pin, and does anybody know where I can get them? Thanks in advance.
