Rear Brake Caliper Slider Pin & Boot Kit OEM TRW for Discovery 3 4 Range Rover Sport L320 L322 Freelander 2 | SMN500040G

Restore smooth and reliable braking performance with this OEM-quality TRW rear brake caliper slider pin and boot kit, part number SMN500040G. Manufactured by TRW, a leading original equipment supplier, this kit is designed to service the rear brake caliper guide pins and restore proper caliper movement.

Caliper slider pins are exposed to heat, dirt and moisture, which can cause them to seize over time if the protective rubber boots fail. This leads to uneven pad wear, brake drag, overheating and reduced braking efficiency. Replacing the pins and boots with a high-quality OEM kit ensures long-lasting performance and reliability.

Compared to cheaper budget kits, TRW components are manufactured to original equipment standards, offering better durability, fit and corrosion resistance.
