Well, on this past ride, I noticed a severe drop in the performance of my front disc. I determined the cause to be a mysterious oil that had somehow found its way all over the bottom of the caliper and rotor. I promptly went home, and cleaned off the rotor/caliper/everything else the oil touched. Then, I spotted the culprit:
In the next pic you'll notice that the crack has changed the angle of the bolt & washers so that it's almost rubbing the rotor.
The good news is I have a back up fork downstairs that's brand new. The bad news is that it's a Manipoo Axel Elite.
If I can find the receit I'll warentee it, but I probably lost it. As a temporary solution I put the V brakes back on, and I'll refill the oil at a later date.
BTW the fork is a Tora 318 Air.
