MPA Electrical B1137 Power Brake Booster

Overview

MPA Electrical B1137 is a remanufactured vacuum power brake booster built for standard replacement applications. It is engineered to deliver strong braking assist with reduced pedal effort, and it is tested at the end of the production line for consistent output.

Compatible with Ford F-250 and Ford F-350 applications, this booster is a direct-fit service part for vehicles that use a vacuum-assisted brake system. The B1137 part number is also useful when cross-checking replacement needs against existing service records.

Key Features

• Vacuum booster design for brake assist with lower pedal effort
• Remanufactured metal housing for service replacement use
• Standard replacement brake service grade
• 9.32-inch diaphragm diameter for the specified application
• 3/8-16 master cylinder stud thread size
• End-of-line tested for output consistency

Detailed Description

MPA Electrical B1137 is a reman vac power brake booster without master cylinder, built around a vacuum booster design and remanufactured metal construction. The unit uses two mounting studs and does not include a brake pedal rod extension, gasket or seal, front seal, mounting bracket, or master cylinder. The B1137 is intended for service replacement where the original vacuum-assisted booster needs to be restored to proper braking assist and pressure transfer.

This part cross-references Ford E0TZ2005B for the same application. It is listed for 1981-1983 Ford F-250 and 1980-1983 Ford F-350, making it a relevant choice when replacing a power brake booster on these trucks. The B1137 part number should be matched carefully to the existing brake system configuration before installation.

What It Helps Address

• Hard brake pedal feel caused by booster wear
• Reduced braking assist from vacuum seal loss
• Inconsistent pedal response during braking
• Pressure transfer issues in the brake assist system
• Replacement needs for a worn remanufactured booster

Installation Notes

Verify vacuum booster style, diaphragm size, stud thread size, and master cylinder interface before installation. This unit is supplied without a master cylinder, so the existing brake system components must be confirmed for reuse or separate replacement. Match the B1137 part number and vehicle application details to the original booster before service.

Quality Assurance

MPA Electrical subjects each unit to 100% end-of-line testing using proprietary equipment. The remanufactured construction and treated internal components are used to support vacuum seal integrity and reliable braking assist.
