Detailed Description

BC186453 is remanufactured at an IATF 16949 facility using a controlled inspection process for core selection, cleaning, machining, and final assembly. During teardown, worn phenolic pistons are replaced with new components, while reusable steel parts are cleaned and inspected before assembly. Cast iron housings receive a corrosion-resistant zinc dichromate coating to help maintain an OE-style appearance and resist rust. Threads are cleaned and chased, and final go/no-go inspection is used to verify proper fit and function. For Mazda 2 front brake service, BC186453 provides a direct replacement option for the front right caliper assembly.

Common Brake Issues It May Address

• Brake drag caused by a sticking caliper piston
• Uneven braking from worn or corroded caliper components
• Fluid seepage at the caliper inlet or sealing surfaces
• Noisy or inconsistent braking from damaged caliper hardware interfaces
• Corrosion-related caliper seizure on the front right brake corner

Installation Notes and Tips

Verify the inlet thread diameter, caliper style, and front right position before installation. Inspect brake hoses, pads, and rotor condition during service, and bleed the hydraulic system after caliper replacement. Because pads are not included, reuse or replace brake pads separately as needed. Confirm that the mounting bracket and slides match the vehicle’s original brake setup before assembly.

Quality Assurance

MPA Electrical remanufactures this caliper through multiple quality checkpoints, including core rejection for heavily pitted or severely corroded units, material checks on rubber components, and final inspection before release. BC186453 is built to support OE-type performance and fitment for the listed Mazda 2 application.
