Detailed Description
MPA Electrical remanufactures this brake caliper at an IATF 16949 facility using a controlled inspection process for core selection, cleaning, machining, and final assembly. Aluminum calipers are machined at the inlet face for a tighter seal, while reusable steel components are cleaned and inspected before assembly. The steel piston design supports OE-style brake function, and the coated silver finish helps protect the caliper housing from rust. For buyers searching for a rear left brake caliper for Scion xB, BC183423 provides a direct replacement option with the correct fitment and hardware configuration.

What It Helps Fix
- Brake fluid seepage at the caliper inlet or piston area
- Uneven rear braking caused by a sticking caliper
- Corrosion on the caliper body or slides
- Reduced brake response from worn internal components
- Noisy or inconsistent rear brake operation on a Scion xB
Installation Notes and Tips
Fits 2008-2015 Scion xB, rear left. Confirm the inlet thread size, caliper style, and bracket layout before installation. Transfer only the components required by the vehicle application, and bleed the brake system after installation to remove air from the hydraulic circuit. Because pads are not included, inspect pad condition and rotor wear before reassembly.
Quality Assurance
Each caliper core is screened through multiple quality checkpoints before remanufacturing. Heavily pitted or severely corroded cores are removed from the process, and final inspection includes thread cleaning and go/no-go verification for proper fit and function. BC183423 is remanufactured to support OE-style performance for the rear left brake system on the Scion xB.
