As a remanufactured Original Equipment part, this unit guarantees a perfect vehicle fit.
All modules are fully tested with automated computerized test equipment to ensure functionality and reliable.
High-pressure hydraulic testing ensures zero leakage for long-lasting performance.
field testing further ensures product reliability.
Air-decay testing ensures zero brake fluid leakage for guaranteed, consistent performance.
Our remanufacturing process is earth-friendly, as it reduces the energy and raw material needed to make a new part by 80 percent.

Tested to SAE J2784 for braking effectiveness, along with Noise/Vibration/Harshness (NVH) and durability/wear testing for assurance of quality.
Ceramic, semi-metallic, and organic formulas provide safety and reliability for a range of vehicle applications.
Integrally molded - friction material molded to backing plate for bond integrity.
Premium shims, slots, and chamfers help to diminish noise, vibration, and braking harshness.
Stamped backing plate allows for proper pad movement within the caliper assembly, reducing noise, brake pulsation, and helps to protect against premature wear.
