Product Overview

BC183131 is remanufactured at an IATF 16949 facility with inspection steps focused on core condition, thread cleanup, and final assembly checks. Aluminum housings are machined at the inlet area for a tight seal, while reusable steel components are cleaned and inspected before assembly. The caliper is finished in a corrosion-resistant coating for OE-style appearance and rust protection. For Lexus ES350, Toyota Avalon, and Toyota Camry rear brake service, this part number BC183131 provides a direct replacement for the rear left disc brake caliper position.

Common Brake Issues This Part Can Address

• Brake fluid leakage at the caliper inlet or sealing surface
• Uneven rear brake pad wear from a sticking caliper
• Reduced braking performance caused by piston or slide wear
• Corrosion on the caliper body or hardware contact points
• Noisy or dragging rear brakes on the affected Lexus and Toyota applications

Installation Notes and Tips

Verify rear left fitment against the vehicle build date before installation, especially for 2012 Lexus ES350 and 2011 Toyota Camry applications with date notes. Transfer only the components required by the vehicle setup, and replace brake fluid after caliper service. Because pads are not included, inspect pad condition and rotor surface before reassembly. Confirm the inlet thread and mounting points match the original caliper before bleeding the system.

Quality Assurance

MPA Electrical remanufactures this caliper through multiple quality-control checkpoints, including core inspection, material checks, thread chasing, and final go/no-go verification. Phenolic pistons are replaced with new components during remanufacturing, and rubber parts are material-tested for consistency. This part number BC183131 is built to meet the listed application requirements for Lexus ES350, Toyota Avalon, and Toyota Camry rear left brake service.
