To replace brake pads:
- Crack loose but don’t fully remove the pad pins yet (use 3 mm hex key).
- Loosen the lower sliding pin of the caliper (use 12 mm wrench).
3. Flip up the caliper.
4. Use a clamping screw on the old brake pads to press in the piston.
5. Fully remove the pad pins and old brake pads. Remove any corrosion from the pad pins with a medium scotch brite pad.
6. Install new brake pads and reassemble. Make sure not to forget the spring washer on the sliding pin! Do not overtighten!
The brake pad change is a good time to give the callipers a clean-up to prevent corrosion and accumulation of dirt. Use a brake-cleaner and an old toothbrush to get into hard-to-reach areas.
While you’re in there, remove the sliding pins from the caliper. Clean and regrease the pins. Use a high-temperature silicone-based grease.
Replace the brake pad pins, if heavily corroded.
Replace the sliding pin spring washers if they remain flat after removal.
Always pump up the brakes after a brake pad change!
