Step-by-Step Fix
Safety & Preparation
Before beginning any repair, ensure you have isolated power or water supplies. Clear your workspace, gather standard hand tools, and wear appropriate personal protective equipment (PPE).
- To begin, carefully remove the wheel if necessary to gain clear access to the brake calliper; for some brake types, you may only need to angle the bike or loosen the calliper. Ensure the bike is stable and supported before proceeding, perhaps using a bike stand or leaning it securely against a wall.
- Once you have access, locate the retaining pin or bolt that holds the brake pads in place and carefully remove it using the appropriate tool. Now, slide the worn brake pads directly out of the calliper body, noting their orientation as you remove them.
- Carefully insert the new brake pads into the calliper, making sure they are facing the correct way and align with the piston or rim/disc surface. For disc brakes, gently push the pistons back into the calliper with a clean, flat tool to create space for the new, thicker pads.
- Adjust the calliper position so the new pads are perfectly centred over the disc rotor without rubbing, or for rim brakes, ensure they make full, flat contact with the rim. Tighten the calliper mounting bolts just enough so it can still be micro-adjusted, ensuring the pads are not catching on spokes or tyres.
- Reinsert the pad retaining pin or bolt you removed earlier, making sure it is fully seated and secure. Finally, tighten the calliper mounting bolts fully to the manufacturer's specified torque, if known, or ensure they are very snug to prevent movement.
- Before riding, always conduct a thorough brake test by spinning the wheel and applying the brakes firmly several times to bed them in and check for proper function and stopping power. Ride cautiously at low speed in a safe area, checking both front and rear brakes work effectively and smoothly before venturing out onto the road.
