MPA Electrical BC186384 Disc Brake Caliper - Rear Left

Overview

This remanufactured disc brake caliper is built for rear left applications on select Volkswagen and Audi models. It uses a cast iron housing, a floating design, and a coated silver finish for a service-ready replacement that matches the original mounting style.

Part number BC186384 is remanufactured at an IATF 16949 facility with quality checks throughout the process. It is a direct fit for applications such as the Volkswagen Beetle, Volkswagen Jetta, and Audi A3, with fitment details varying by brake package and build date.

Key Features

• Remanufactured disc brake caliper for rear left installation
• Cast iron caliper body with coated silver finish
• Floating caliper design with one steel piston
• Mounting bracket and caliper slides included
• Brake pads and mounting bolts not included
• Fits select Volkswagen and Audi rear brake applications

Product Details

BC186384 is a remanufactured brake caliper engineered around OE-style service requirements. The cast iron housing is coated for corrosion resistance, while the steel piston and cleaned threads are prepared for proper assembly and sealing. This part cross-references Monroe Shocks & Struts (e.g., 5K0615423) for the same application.

Compatible fitment includes 2015-2017 Volkswagen Beetle, rear left; 2011-2014 Volkswagen Jetta, rear left; and 2010-2013 Audi A3, rear left. Additional coverage includes select Volkswagen Eos, Golf, GTI, Passat, Bora, and Audi A3 Quattro applications. Always verify brake disc diameter, engine code, and build date before ordering.

Common Repair Uses

• Restores braking performance when the caliper is sticking or seized
• Addresses fluid leakage caused by worn internal sealing surfaces
• Replaces a corroded or pitted caliper housing
• Corrects uneven rear brake wear from a failing piston or slide assembly
• Helps resolve brake drag, noise, or reduced pedal response

Installation Notes

Confirm rear left fitment against the vehicle's brake package, disc diameter, and build date before installation. The inlet thread diameter is 10.0 mm and the mounting hole diameter is 12.0 mm. Because this is a remanufactured hydraulic component, the brake system should be inspected, bled, and checked for leaks after installation.

Quality Assurance

MPA Electrical remanufactures calipers through multiple QC checkpoints, including core inspection, thread cleaning, final go/no-go testing, and material checks on rubber components. Cast iron calipers receive a corrosion-resistant zinc dichromate coating for OE-style protection and appearance.
