Was desert riding over the weekend and somehow managed to hit a boulder and break off the front brake caliper. I have a front disc/caliper guard, but evidently, this was not enough protection. The mounts on the fork leg are OK, but the caliper is toast. The rotor is stock size and I need to know what the best caliper replacement would be. Anybody got an stock used front brake caliper for sale for a 2000 WR400?
