MPA Electrical BC186811 Disc Brake Caliper - Rear Left

Remanufactured Rear Left Brake Caliper

MPA Electrical BC186811 is a remanufactured disc brake caliper for the rear left position on select Kia Rio models. It is built for 2012-2016 Kia Rio and 2017-2018 Kia Rio applications, including the 2017-2018 rear left Kia Rio except Mexico-built vehicles. This part number, BC186811, is remanufactured with inspection-focused processes to support OE-style brake performance.

Key Features

• Remanufactured floating disc brake caliper
• Rear left position for select Kia Rio applications
• Cast iron caliper body with coated silver finish
• Steel piston construction
• Mounting bracket and caliper slides included
• 10.0 inlet thread diameter
• Pads not included
• Mounting bolts not included

Product Details

BC186811 is remanufactured at an IATF 16949 facility using a multi-step inspection process that starts with core selection and rejects heavily pitted or severely corroded cores. During teardown and rebuild, threads are cleaned and chased, reusable steel components are cleaned and inspected, and rubber components are material tested before assembly. Cast iron calipers receive a corrosion-resistant zinc dichromate coating for added rust protection and an OE-style appearance. The result is a rear left Kia Rio brake caliper designed around the original hydraulic and mounting specifications, with a floating caliper design, one steel piston, and included slides and bracket for the listed applications. This part cross-references 583001W300 for the same application.

Common Brake Issues It May Address

• Sticking or seized rear left caliper movement
• Uneven rear brake pad wear
• Brake fluid leakage at the caliper inlet or seals
• Corrosion-related caliper binding
• Reduced braking response from a worn hydraulic caliper

Installation Notes

Verify rear left fitment by year, model, and build origin before installation. Fits 2012-2016 Kia Rio, rear left, and fits 2017-2018 Kia Rio, rear left, except Mexico built. Confirm the 10.0 inlet thread diameter, bracket alignment, and slide operation during installation. Brake pads are not included, and mounting bolts are not included, so reuse or replacement should be planned separately as needed. Bleed the brake system after installation and inspect for leaks, proper pedal feel, and even caliper movement.

Quality Assurance

MPA Electrical remanufactures this caliper in an IATF 16949 facility with core rejection criteria, final inspection, thread chasing, and material checks on rubber components. Aluminum caliper machining, zinc dichromate coating on cast iron units, and replacement of phenolic pistons with new components where applicable are part of the remanufacturing process used across the brand’s brake caliper program. BC186811 is built to meet the listed application requirements for Kia Rio rear left brake service.
