Installation Notes and Tips

Ensure the mounting bracket is present and compatible, as this caliper requires a bracket for installation. Although mounting hardware is not included, the package contains abutment clips and a bleeder screw to assist with setup. Verify inlet and bleeder screw thread sizes (M10x1.5) match your vehicle’s brake lines and fittings. Properly bleed the brake system after installation to remove air and maintain braking performance. Use OEM or recommended brake pads, as pads are not included with this caliper.
