TechShield 360 (tm) identifies Nugeon’s protected remanufactured brake component line. For this caliper, that means a rust-preventative finish, replacement dust boots, and hardware included where applicable to support a clean brake service on the front axle. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Problems This Caliper Can Address

• Brake drag caused by a sticking or seized front left caliper
• Uneven pad wear from worn piston seals or slide components
• Brake fluid leakage at the caliper body or bleeder area
• Corrosion on the caliper housing or piston surfaces
• Poor braking response from a failing hydraulic caliper assembly

Installation Notes and Tips

Verify front left position, bracket style, inlet thread size, and bleeder screw thread before installation. This caliper uses a banjo bolt inlet and M10-1.5 inlet threads, with an M10-1.0 bleeder screw thread. Brake pad installation hardware and banjo bolt/copper crush washers are included where applicable, but pads are not included. Always bleed the brake system after installation and confirm proper caliper slide movement before returning the vehicle to service.
