Detailed Description

BC186452 is remanufactured at an IATF 16949 facility with inspection steps focused on core condition, thread quality, sealing surfaces, and reusable metal components. Heavily pitted or severely corroded cores are removed from the process early, while reusable steel parts are cleaned and checked before assembly. The cast iron housing receives a corrosion-resistant coating for OE-style appearance and added rust protection. For Mazda 2 front brake service, BC186452 provides a direct-fit replacement caliper for the 2011-2015 model years.

Common Problems This Part Can Address

• Sticking or dragging front left brake caliper operation
• Uneven brake pad wear caused by caliper piston or slide issues
• Brake fluid leakage at the caliper inlet or sealing surfaces
• Corrosion-related caliper seizure on a cast iron housing
• Reduced braking performance from a worn remanufactured caliper assembly

Installation Notes and Tips

Confirm the vehicle is a 2011-2015 Mazda 2 with front left caliper application before ordering. Inspect brake hoses, pads, rotors, and slide hardware during service, and verify the inlet thread size matches the original setup. Because pads and mounting bolts are not included, reuse or replace related service parts as needed during installation. Bleed the brake system after installation and check for leaks at the banjo and inlet connections.

Quality Assurance

MPA Electrical remanufactures this caliper with QC checkpoints throughout teardown, cleaning, machining, assembly, and final inspection. Phenolic pistons are replaced with new components during remanufacturing, rubber parts are material-tested, and threads are cleaned and chased for OE-type performance. Cast iron calipers are finished with zinc dichromate-style corrosion protection to support long-term service life.
