Ensure the brake system is properly bled after installation to remove air and maintain optimal brake pedal feel. Verify that the mounting bracket and caliper slides are securely installed to prevent caliper movement during operation. Use the correct inlet thread size (10.0 mm) for brake line connections. Although mounting hardware is included, mounting bolts are not; verify bolt condition and replace if necessary. Follow vehicle-specific service manual instructions for torque specifications and safety precautions.
