  • Fits 2011 Mazda 3 Sport, rear right

Detailed Description

BC186285 is remanufactured at an IATF 16949 facility using a multi-step inspection process that removes heavily pitted or severely corroded cores before assembly. Aluminum calipers are machined at the inlet face to support a tight seal, while rubber components are material tested and all phenolic pistons are replaced with new parts during remanufacturing. For Mazda 3 rear brake service, this caliper provides a direct replacement for the specified rear right application and is identified by part number BC186285.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Repair Symptoms

  • Rear brake drag or uneven braking on the right side
  • Brake fluid seepage at the caliper inlet or piston area
  • Corrosion on the caliper body or slide surfaces
  • Sticking piston movement after brake application
  • Poor rear brake response during service inspection

Installation Notes and Tips

  • Verify rear right position and vehicle fitment before installation.
  • Inspect brake hoses, pads, and rotor condition during caliper replacement.
  • Bleed the brake system after installation to remove air from the hydraulic circuit.
  • Confirm inlet thread size and banjo connection details match the vehicle setup.
  • Follow factory torque specifications and brake service procedures.

Quality Assurance

MPA Electrical remanufactures this caliper through QC checkpoints that include core inspection, cleaning, thread chasing, final inspection, and material checks on reusable components. Cast iron calipers in the line receive corrosion-resistant zinc dichromate coating, and all remanufactured units are assembled to support OE-style performance and sealing integrity.
