Detailed Description

MPA Electrical B3107 is a remanufactured vacuum power brake booster engineered to restore brake assist performance in vehicles that rely on vacuum-assisted braking. The unit uses a metal housing and a 10.69-inch diaphragm diameter to support pressure transfer through the brake system, while the 8 x 1.25 mm master cylinder stud thread size helps match the specified mounting interface. This part cross-references Toyota 44610-02630 and 4461002630 for the same application. For Toyota Corolla, Toyota RAV4, Scion tC, Scion xB, and Toyota Matrix applications, B3107 provides a direct replacement format for the listed fitments.

What It Helps Address

• Hard brake pedal feel caused by reduced vacuum assist.
• Inconsistent braking response from a worn booster assembly.
• Loss of pressure transfer through a failing internal diaphragm or seal.
• Fitment issues when replacing the original booster with the correct remanufactured unit.

Installation Notes

Verify the master cylinder is not included before installation. Confirm the booster type, stud thread size, and mounting interface against the original part before removal. Use the listed fitment data to match the correct Toyota Corolla, Toyota RAV4, Scion tC, Scion xB, or Toyota Matrix application.

Quality Assurance

MPA Electrical subjects each unit to 100% end-of-line testing using proprietary equipment. The remanufactured construction and treated components are used to support vacuum sealing and pressure transfer consistency.
