Installation Notes and Tips
Ensure the brake system is fully depressurized before removing the old caliper. This caliper includes mounting brackets and abutment clips, but brake pads and pad wear sensors must be sourced separately. Verify the inlet fitting type and thread size (M10x1.0) match your vehicle’s brake lines. Bleed the brake system thoroughly after installation using the included bleeder screw to remove air and maintain optimal brake performance.
