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 consistent operation. This B1019 unit uses a vacuum booster design with a dual diaphragm to help transfer pedal input into braking assist efficiently. The remanufacturing process includes new replacement and specially treated components to support vacuum sealing and pressure transfer, and each unit is end-of-line tested before release.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Hard brake pedal feel
• Reduced brake assist from a failing vacuum booster
• Inconsistent stopping response
• Vacuum seal loss in the brake booster assembly
• Brake performance concerns on aging Silverado, Sierra, Tahoe, Yukon, and Escalade platforms

Installation Notes

Verify master cylinder fitment, stud thread size, and mounting layout before installation. This booster does not include the master cylinder, so transfer or replace related brake components as needed during service. Confirm vehicle application against the listed fitment for 1999-2002 Chevrolet Silverado 1500, 2000-2002 Chevrolet Tahoe, 2000-2002 GMC Yukon, and the other supported Cadillac, Chevrolet, and GMC models.

For best results, inspect vacuum supply, brake pedal linkage, and surrounding brake hardware before installing the B1019. Proper system checks help ensure the replacement booster performs as expected after service.

Quality Assurance

MPA Electrical subjects each brake booster to 100% end-of-line testing using proprietary test equipment. The remanufactured construction and tested vacuum sealing are used to support reliable brake assist performance in the listed applications.
