Detailed Description

MPA Electrical B1009 is engineered for Chevrolet and GMC full-size truck and SUV brake systems that use a vacuum-assisted booster. The dual diaphragm layout helps deliver strong braking assist with lower pedal effort, while the remanufactured construction uses treated and replacement components to maintain vacuum sealing and pressure transfer. This part cross-references Monroe Shocks & Struts (e.g., 18012114) for the same application.

What It Helps Address

• Hard brake pedal feel caused by a weak or leaking booster
• Reduced brake assist during normal stopping
• Vacuum loss at the booster housing or diaphragm assembly
• Inconsistent pedal response in older GM truck brake systems
• Brake performance concerns on remanufactured replacement service

Installation Notes and Tips

Verify the master cylinder stud thread size is 10 x 1.50 mm before installation. This booster does not include a master cylinder, gasket or seal, front seal, or mounting bracket, so reuse or source the required related components as needed for the vehicle. Confirm the vehicle uses a vacuum booster setup and match the original mounting stud layout and brake system configuration before installation.

Quality Assurance

MPA Electrical remanufactures this booster with specially treated and replacement components, then subjects every unit to 100% end-of-line testing using proprietary equipment to confirm performance, vacuum sealing, and pressure transfer. B1009 is built to meet standard replacement service expectations for select Chevrolet and GMC applications.
