Remove the wheel and use a 15mm socket to remove the brake caliper bolts. Set the caliper aside and replace the pads. You will need a C-Clamp to push the caliper piston back in to accommodate the new pads. You will need to remove some of the brake fluid from the master cylinder before you push the caliper piston in because the fluid level will rise. If you do not remove any fluid it will over flow and make a mess. BRAKE FLUID EATS PAINT. Reassemble and pump the brakes. Add fluid if needed.
