Detailed Product Description

The B5001 power brake booster is a hydraulic type booster designed to assist braking effort by using hydraulic pressure rather than vacuum. Its metal housing ensures durability under demanding conditions. This remanufactured booster is intended as a direct replacement for original equipment on various Chevrolet and GMC models, including Avalanche 1500 and 2500, Sierra 1500 series, Silverado 1500 and 2500 series, Suburban 2500, and Yukon XL 2500. Note that this unit does not include the master cylinder, brake pedal rod extension, or gaskets/seals, so those components must be sourced separately if needed.

Common Applications and Issues Addressed

• Restores brake assist on hydraulic brake systems in Chevrolet Avalanche and GMC Sierra trucks
• Replaces faulty or worn power brake boosters causing hard brake pedal feel
• Addresses brake pedal travel inconsistencies due to booster failure
• Eliminates reduced braking efficiency from booster leaks or internal damage
• Supports brake system maintenance on Silverado 1500 HD and Suburban 2500 models

Installation Notes and Tips

Ensure compatibility with your vehicle’s make and model before installation. This booster includes a mounting bracket and two mounting studs for secure attachment. Verify the master cylinder stud thread size (10 x 1.50 mm) matches your existing master cylinder. Since the master cylinder and brake pedal rod extension are not included, inspect these components for wear and replace if necessary. Proper bleeding of the hydraulic brake system after installation is recommended to maintain optimal brake performance.

This remanufactured power brake booster undergoes thorough testing to meet standard replacement quality. MPA Electrical provides assurance of product reliability consistent with OEM specifications. Warranty details should be confirmed at the point of purchase, as coverage may vary.
