Detailed Description

MPA Electrical B1011 is a remanufactured vacuum brake booster engineered for 1999-2004 Jeep Grand Cherokee models. It is built to restore vacuum-assisted braking performance by increasing assist while reducing the pedal effort required during normal braking. The dual diaphragm layout and 230.12 mm (9.06 in.) diaphragm diameter support consistent pressure transfer in the brake system.

This part is supplied without the master cylinder, gasket or seal, front seal, mounting bracket, or brake pedal rod extension, so it is intended for service where those components are reused or sourced separately as needed. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. Part Number B1011 is a direct replacement option for Jeep Grand Cherokee brake booster service.

Common Problems This Part Helps Address

• Hard brake pedal feel
• Reduced vacuum assist during braking
• Longer stopping distance caused by booster performance loss
• Brake pedal effort that increases over time
• Brake booster replacement after vacuum seal deterioration

Installation Notes and Tips

Verify the master cylinder stud thread size, mounting stud layout, and booster depth before installation. Transfer or replace related brake components only as required by the vehicle service procedure, and inspect the vacuum supply line, check valve, and pedal linkage for wear before final assembly. Confirm fitment against the 1999-2004 Jeep Grand Cherokee application and compare the original booster to Part Number B1011 before installation.

Quality Assurance

MPA Electrical states that these brake boosters are tested at the end of the production process using proprietary equipment to verify vacuum seal integrity and pressure transfer performance. The remanufactured construction and replacement-focused design support dependable brake system service for Jeep Grand Cherokee applications.
