Detailed Description

MPA Electrical B1018 is a reman vac pwr brake booster w/o master cyl designed for Chevrolet Blazer, Chevrolet C10, Chevrolet K5 Blazer, GMC Jimmy, GMC C1500, GMC K2500, and other GM full-size truck and SUV platforms from 1981 through 1991.

Installation Notes and Tips

Verify master cylinder compatibility before installation, since the master cylinder is not included with this booster. Confirm the 10 x 1.50 mm stud thread size and check pedal rod and mounting alignment against the original unit. For best results, inspect the vacuum supply, check valve, and brake hydraulic components before replacing the booster.
