Brake Caliper Guide Pins

Brake Caliper Guide Pins

CAUTION: Do not use power tools for caliper guide pin bore cleaning.

The guide pins should slide with a reasonable amount of hand force. If the brake pads show taper wear or if the guide pins are difficult to move, then carry out the following steps.

NOTE: If a guide pin kit is not available, install a new caliper assembly.

^ Disassemble the guide pins.
^ Use a wire brush, rolled-up sandpaper or emery cloth to remove all corrosion and foreign material from the caliper guide pin bores. Clean any remaining debris from the bores with brake parts cleaner and compressed air.
^ Install new brake pads if the lining is not within specifications.
^ Assemble the caliper guide pins using new caliper seals, boots and guide pins. Use an ample amount of silicone grease to lubricate the bores and guide pins.
