Before you loosen the caliper mounting bolts, clamp off the rubber brake line to prevent nasty spills, and also to keep the master cylinder from running dry. Make sure you keep a close eye on it throughout the whole process, otherwise you'll be in a world of hurt. Now we can remove the brake line from the caliper with minimum fluid loss. Next, remove the caliper. I took a little time here to clean the spindle and dust shield with a parts cleaner.
