MPA Electrical B3051 is a remanufactured vacuum power brake booster built for drivers who need consistent brake assist and a firm, predictable pedal feel. This standard replacement unit is engineered for direct service on applications that use an 8.55 in. diaphragm and a 2-stud mounting pattern.
Compatible With Hyundai Elantra and Kia Forte applications that use this vacuum booster design, B3051 is a practical replacement when the original booster no longer holds vacuum or delivers proper pedal assist. This part cross-references Hyundai/Kia OE numbers 47210N3001 and 47210N4300 for the same application.

Product Details
The MPA Electrical BrandLine reman vac power brake booster line focuses on restoring vacuum-assisted braking performance with replacement and specially treated internal components.

Common Brake Issues This Part Addresses
- Hard brake pedal feel
- Reduced brake assist during stops
- Vacuum leak at the booster housing
- Inconsistent pedal response after booster wear
- Brake system performance loss from a failing reman booster
Installation Notes
Verify the diaphragm diameter, mounting stud pattern, and master cylinder stud thread size before installation. Transfer the master cylinder from the existing brake system if required by the application, and inspect the vacuum hose, check valve, and pedal linkage for wear before reassembly. Proper bleeding and system inspection after installation help confirm correct brake operation.

MPA Electrical remanufactures this booster with replacement and specially treated components, then subjects each unit to 100% end-of-line testing using proprietary equipment to confirm vacuum seal integrity and pressure transfer performance.
