Product Details

MPA Electrical B1013 is designed for drivers who need a replacement brake booster that restores vacuum-assisted braking performance without changing the master cylinder.

Installation Notes

Verify master cylinder compatibility before installation, since the master cylinder is not included. Confirm the 10 x 1.50 mm stud thread size, two-stud mounting pattern, and pedal rod extension configuration against the original unit. Inspect vacuum supply, brake lines, and mounting surfaces during replacement to help ensure proper brake system operation.
