Hack Engineering Brass Brake Caliper Slider Bushes
Many problems with brake feel, vibration, uneven wear and poor braking performance while using the OE BMW single piston sliding caliper design are due to the flexible rubber bushes that the calipers slide along. Our precision-machined brass bushes eliminate all unwanted movement and allow the caliper to much more evenly use the brake pads for improved performance and longevity. Priced per axle set (4 bushes with clips).
Fits all BMW/ATE single-piston sliding calipers. Will not fit Girling or Brembo parts. These parts require periodic lubrication – when installing please ensure that the sliding pins are not corroded or damaged – replace if this is the case (BMW part number 34111157041).
