Installation Notes and Tips
Verify rear left fitment against the vehicle year, brake setup, and notes before installation. This caliper uses a banjo bolt inlet and M10-1.0 inlet thread, so confirm the brake hose connection and copper crush washer requirements for your application. Inspect the rotor, pads, and brake hose condition during service, and bleed the hydraulic system after installation to remove air from the circuit.
