Product Details

MPA Electrical’s Reman Vac Pwr Brake Booster w/o Master Cyl line focuses on remanufactured brake assist components that are tested for vacuum sealing and pressure transfer performance. For drivers servicing a Chrysler Town & Country, Dodge Grand Caravan, or Ram C/V, B1388 provides a direct-fit vacuum booster solution where the original unit has lost assist or developed pedal-related braking issues. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Issues This Part Can Address

• Hard brake pedal feel
• Reduced vacuum brake assist
• Longer stopping distance caused by booster loss
• Brake pedal effort that has increased over time
• Vacuum seal problems in the brake booster assembly

Installation Notes

Verify the master cylinder stud thread size, mounting stud layout, and diaphragm diameter before installation. Because the master cylinder is not included, transfer or replace related brake components as needed during service. Always inspect vacuum supply lines, pedal linkage, and mounting surfaces before final assembly. Confirm vehicle-specific fitment for 2011-2016 Chrysler Town & Country, 2011-2014 Dodge Grand Caravan, and 2012-2015 Ram C/V applications.

Quality Assurance

MPA Electrical remanufactures and tests each brake booster with end-of-line equipment to verify vacuum seal integrity and pressure transfer performance. The remanufacturing process uses new replacement and specially treated components to support consistent braking assist in service.
