Detailed Product Features and Specifications

This remanufactured caliper from BBB Industries is constructed with a durable aluminum casting that offers corrosion resistance and weight savings. The gray caliper finish provides rust prevention to extend service life. It includes a single phenolic piston, which helps reduce heat transfer to the brake fluid, improving overall braking consistency. The caliper comes with caliper slides and a mounting bracket to ensure proper alignment and fitment during installation.

The inlet fitting uses a banjo bolt design with an M10-1.0 thread, compatible with the specified vehicle brake lines. A bleeder screw (M10-1.0 x 32) is included to facilitate brake fluid bleeding during installation. Dust boots are provided to protect internal components from contaminants. While brake pads are not included, the package contains all necessary pad installation hardware to complete the brake job.
