  • Addresses noise or vibration issues related to caliper malfunction
  • Improves braking performance after corrosion or physical damage to original caliper

Installation Notes and Tips

Ensure compatibility with your vehicle’s make and model before installation. The caliper includes the necessary bracket and bleeder screw but does not include anti-squeal shims or grease pack. Use the correct M10-1.0 thread size fittings for brake line connections. Properly torque mounting bolts and bleed the brake system thoroughly to remove air and ensure optimal braking performance. Inspect brake pads (FMSI number D1809) and replace if worn, as pads are not included with this caliper.
