APR BRK00028 BBK Vehicle Fitment:
APR BBK Manufacturing: APR BBK Calipers are an FEA optimized design for maximum strength and rigidity. The lightweight six piston calipers are manufactured from billet aluminum with a UV and temperature resistant anodized black finish. The aluminum pistons are hand polished to a mirror finish before being hard-anodized. The pistons glide on ultra-high temperature pressure and wiper seals. Maximum Temperature Recording (MTR) devices are attached to the backside of the caliper.
APR Rotor Rings measure 380x34mm and feature curved vanes to maximize internal airflow and are coated to prevent oxidation on unswept areas of the rotor. Temperature recording paint is applied to the outside of the rotor rings.
APR Rotor Hats and caliper brackets are machined from billet aluminum with a hard anodized finish featuring laser etched logos.
APR Brake Lines consist of an expansion resistant Teflon inner line, which is then covered with a layer of stainless steel woven braid and coated with a clear abrasion resistant cover. The stainless steel braid provides support for the Teflon and is extremely durable against incidental impact and abrasion, the coating provides maximum protection against chaffing and particle intrusion.
APR Brake Pads are a FMSI D1116 shaped high-performance street pad which is also suitable for light track sessions. The pads deliver strong braking performance across a wide temperature range yet are conservative for disc wear. The pad's co-efficient of friction delivers reduced stopping distances and improved fade resistance compared to most factory compounds. The material exhibits a slightly rising torque curve through a single braking application causing the brakes to feel positive, but not overly aggressive, during initial engagement. This further results in gradually increased friction levels during the braking cycle, making the compound perfect for the grip associated with high performance street tires during medium to hard brake applications. Lastly, the pads feature a thermal barrier between the friction material and pad backing plate to maximize the life of the seals and fluid.
APR brakes are warranted to be free from defects in the materials and workmanship prior to installation. This warranty does not cover labor, misuse, faulty installation, failure of related parts or parts purchased other than from APR, LLC. This warranty extends to the original purchaser for as long as they own the vehicle and the product .
