Product Details and Specifications

These disc brake pads feature a semi-metallic friction material composition, which offers a good balance between braking efficiency and pad longevity. Both the inner and outer pads have a friction material thickness of 19.60 mm, contributing to longer wear intervals. The steel backing plate provides strength and stability, while the friction material is integrally molded to the backing for secure attachment. The pads are prepared for pad wear sensors, allowing easy integration with existing vehicle systems, although the sensors themselves are not included. Chamfered edges help reduce noise and vibration during braking. The pads measure 148.20 mm in width and 69.80 mm in height for both inner and outer pads, matching the exact fitment requirements for the specified BMW models.

Installation Notes and Tips

These brake pads do not include mounting hardware, pad shims, or abutment clips, so ensure existing components are inspected and replaced if necessary. The pads are prepared for pad wear sensors, but sensors must be sourced separately if required. Proper cleaning of the caliper and rotor surfaces before installation is recommended to ensure optimal performance. Chamfered edges help reduce noise, but correct installation orientation is important to maintain this benefit.
