Technical Description and Features

This disc brake caliper features a cast iron body that offers durability under typical driving conditions.

The gray color finish is standard for OE replacement parts, and the included mounting bracket facilitates proper installation. The bleeder screw with an M10 x 1.0 thread size allows for effective brake fluid bleeding during maintenance.

Installation Notes and Tips

Ensure the brake system is properly bled after installation to remove air from the hydraulic lines. The mounting bracket is included, but mounting hardware is not, so verify you have the necessary bolts and tools before beginning. Use the correct bleeder screw size (M10 x 1.0) for brake fluid maintenance. Inspect brake pads and rotors for wear and replace if necessary to ensure optimal braking performance.
