Installation Notes and Tips

Ensure the brake system is properly bled using the included bleeder screw to remove air and maintain hydraulic integrity. Verify compatibility with your vehicle’s axle position as this caliper is designed for trailing axle use. Since brake pads and pad wear sensors are not included, select compatible pads separately. Use the included mounting bracket and abutment clips for secure installation. Follow manufacturer torque specifications for inlet fittings and mounting hardware.
