Installation Notes and Tips

Verify rear right fitment before installation on 2008-2015 Scion xB models. Inspect brake hoses, pads, rotors, and fluid condition during service, and confirm the 10.0 mm inlet thread connection matches the vehicle brake line. Bleed the hydraulic system after installation and check for leaks at the banjo and inlet connections where applicable.

Quality Assurance

MPA Electrical remanufactures this caliper through multiple quality checkpoints, including core rejection criteria, component inspection, thread chasing, and final go/no-go testing. Phenolic pistons are replaced with new parts during remanufacturing, and rubber components are material tested to support consistent brake system performance. BC183422 is built to OE-style standards for the specified Scion xB rear right application.
