- 5mm Allen
- Flathead screwdriver

Step 1. Remove the wheel.
Step 2. Compress the brake piston back into the caliper by inserting a flathead screwdriver between the caliper and the outer brake pad, and levering against the caliper.
NOTE: The piston must be compressed into the caliper so there is enough room to fit the new brake pads over the brake disc.
Step 3. Remove the 5mm Allen cap at the rear of the caliper, followed by the two 15mm brake caliper mounting bolts, and then slide the caliper assembly off the brake disc.
Step 4. Pull the caliper mount from the caliper body. Inspect the two rubber boots and replace them if they are split or worn. Clean the caliper mount, then grease the mount's slide pins and reinstall the mount into the caliper body.
Step 5. Install the new brake pads.
Step 6. Slide the caliper assembly back over the brake disc, then reinstall the two caliper mounting bolts and the 5mm Allen cap.
Step 7. Reinstall the wheel.
