REAR DISC BRAKE PADS. Rear disc brake pads are friction components of the vehicle braking system designed to generate braking force by pressing against the brake disc under hydraulic pressure from the caliper. The operating principle is based on converting kinetic energy into heat through friction, ensuring controlled deceleration and vehicle stability. Each pad consists of a steel backing plate bonded to a friction material compound that may be semi-metallic, ceramic or organic depending on performance and temperature requirements. Proper function directly affects braking balance, parking brake efficiency and overall safety. Wear symptoms include increased stopping distance, squealing noise, vibration, uneven disc wear or activation of the wear sensor. Causes of premature wear may involve seized caliper guides, overheating or poor-quality materials. Our catalog includes genuine OEM rear disc brake pads, certified aftermarket alternatives and inspected used sets with adequate friction thickness. Used pads are checked for remaining material thickness and absence of structural damage. Selection is based on VIN number, brake system type, disc diameter and part number. Replacement is recommended in axle sets with inspection of brake discs. Timely installation ensures reliable braking performance and driving safety.
