Detailed Product Description

Installation Notes and Tips

Ensure the brake system is fully depressurized before removing the old caliper. This caliper includes the mounting bracket, abutment clips, and caliper slides, but mounting hardware and anti-rattle springs are not included and may need to be sourced separately. Verify thread sizes for inlet and bleeder screws (M10x1.5 and M10x1.0 respectively) to ensure compatibility with your brake lines. Properly bleed the brake system after installation to remove air and restore brake pedal firmness.
