Technical Description and Features

This disc brake caliper features a cast iron body that withstands the rigors of daily driving and braking demands. The single piston, made from steel, measures 41.15 mm in diameter, providing consistent pressure on the brake pads. The floating caliper design allows for smooth movement, aided by the included caliper slides, which help reduce uneven pad wear. The gray finish protects against corrosion, while the included mounting bracket simplifies installation. The bleeder screw with an M10 x 1.0 thread size facilitates proper brake fluid bleeding during maintenance.

  • Addresses uneven brake pad wear caused by faulty caliper slides
  • Resolves brake drag or sticking issues due to piston corrosion or damage

  • Improves rear brake performance and safety on compatible vehicles

Installation Notes and Tips

Ensure the vehicle is securely lifted and supported before beginning installation. The PowerStop L5015 caliper includes the mounting bracket and caliper slides but does not include mounting hardware, so retain original bolts or source replacements as needed. Properly bleed the brake system using the M10 x 1.0 bleeder screw to remove air and maintain brake responsiveness. Inspect brake pads and rotors for wear and replace if necessary to ensure optimal braking performance.
