Product Details

MPA Electrical B3415 is part of the Reman Vac Pwr Brake Booster w/o Master Cyl line, a product line focused on remanufactured vacuum boosters for replacement brake service. Each unit is end-of-line tested with proprietary equipment to verify vacuum sealing and pressure transfer performance before release. This makes the B3415 a practical choice when replacing a worn booster on a Dodge Ram 50, Dodge Power Ram 50, or Mitsubishi Mighty Max with the correct vacuum booster configuration.

This part cross-references Monroe Shocks & Struts (e.g., MB082277) for the same application.

Common Problems It Can Address

• Hard brake pedal feel
• Reduced brake assist from a leaking booster diaphragm
• Vacuum loss at the brake booster
• Inconsistent pedal response during braking
• Brake assist issues caused by booster wear or internal seal failure

Installation Notes

Verify the vehicle’s booster style, diaphragm size, mounting stud layout, and master cylinder stud thread size before installation. This unit does not include a master cylinder, brake pedal rod extension, gasket or seal, front seal, or mounting bracket, so reuse or source the correct related components as needed. Confirm fitment for 1978-1983 Dodge Challenger, 1979-1982 Dodge D50, 1983-1986 Dodge Ram 50, 1983-1986 Dodge Power Ram 50, and 1983-1986 Mitsubishi Mighty Max before service.
