MPA Electrical BC186992 Disc Brake Caliper - Rear Left

Remanufactured Rear Left Brake Caliper

MPA Electrical BC186992 is a remanufactured rear left disc brake caliper for select Lexus and Toyota applications. It is built for 2012-2017 Toyota Camry rear left, 2013-2018 Lexus ES300h rear left, 2013-2018 Lexus ES350 rear left, and 2013-2018 Toyota Avalon rear left fitments.

This aluminum floating caliper uses a steel piston, includes the caliper slides and mounting bracket, and arrives with a coated silver finish. It is a direct replacement for rear brake service where the original caliper has seized, leaked, or shown corrosion.

Detailed Description

BC186992 is remanufactured at an IATF 16949 facility with inspection steps focused on core condition, thread cleanup, final go/no-go checks, and material verification of rubber components. Aluminum housings are machined at the inlet area for a tighter seal, while reusable steel components are cleaned and inspected before assembly. New phenolic pistons are not used here; this unit uses a steel piston construction as specified. The result is a rear left brake caliper for Toyota Camry, Lexus ES300h, Lexus ES350, and Toyota Avalon applications that matches the original mounting and hydraulic interface requirements.

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

What It Helps Fix

• Brake fluid leakage at the rear caliper
• Sticking or seized rear brake piston movement
• Uneven rear brake pad wear
• Corrosion on the caliper body or hardware surfaces
• Poor rear brake response from a worn original caliper

Installation Notes

Verify rear left fitment by year, make, model, and brake configuration before installation. Transfer only the components required by the vehicle application and confirm the banjo connection, inlet thread size, and mounting points match the original caliper. Bleed the brake system after installation and inspect for leaks before returning the vehicle to service. Pads are not included, so inspect pad condition and replace as needed during caliper service.

Quality Assurance

MPA Electrical remanufactures this caliper through multiple QC checkpoints, including core rejection for heavily pitted or severely corroded units, thread chasing, final inspection, and material checks on rubber parts. The caliper is built to OE-style standards for the listed Lexus and Toyota rear left applications, including BC186992.
