Product Details

MPA Electrical B5012 is designed to restore hydraulic brake assist in Ram truck brake systems where consistent pressure transfer and reduced pedal effort are needed. The remanufactured construction uses specially treated replacement components to support vacuum sealing and dependable operation, while end-of-line testing verifies each unit before release. This part cross-references 5093406AA and 5179891AA for the same application.

Common Brake Issues It Can Help Address

• Hard brake pedal feel
• Reduced brake assist during stopping
• Inconsistent pedal response
• Brake booster leakage concerns
• Loss of hydraulic pressure transfer in the booster assembly

Installation Notes

Confirm the hydraulic booster style, mounting points, and master cylinder stud thread size before installation. This unit is supplied without the master cylinder, so transfer or replacement of the master cylinder must be handled separately. Verify all brake system connections, bleed the system as required, and inspect related hydraulic components for wear before returning the vehicle to service.

Quality Assurance

MPA Electrical subjects each booster to 100% end-of-line testing using proprietary test equipment to confirm function and performance before shipment.
