Product Details

This MPA Electrical brake booster is engineered to restore vacuum-assisted braking performance with minimal pedal effort. The dual diaphragm design and treated replacement components are used to support vacuum sealing, pressure transfer, and consistent brake assist.

What It Helps Address

• Hard brake pedal feel
• Reduced vacuum brake assist
• Brake booster diaphragm wear
• Vacuum seal loss in the booster housing
• Brake assist inconsistency during stopping

Installation Notes

Verify master cylinder compatibility before installation, since the master cylinder is not included. Confirm the 2-stud mounting pattern, 3/8-16 stud thread size, and booster-to-firewall fitment before removal of the original unit. Inspect vacuum supply, check valve condition, and brake pedal linkage setup during replacement to help ensure proper brake assist operation.

Quality Assurance

MPA Electrical subjects each unit to 100% end-of-line testing using proprietary test equipment. The remanufacturing process uses new replacement and specially treated components to support vacuum seal integrity and reliable pressure transfer.
