Raybestos MC39116 Brake Master Cylinder PG Plus

Raybestos MC39116 Brake Master Cylinder PG Plus is a professional-grade replacement master cylinder designed to restore hydraulic braking on classic Ford applications, including late-1970s F-Series trucks and Econoline vans. The part is specified to fit 1977–1979 Ford F-350 and 1977–1983 Ford Econoline models and replaces the original MC39116 (2539116) in those vehicles. It is marketed under Raybestos' PG Plus Professional Grade line, with some listings also identifying the same unit under the Element3 label. Availability and labeling can vary by retailer, reflecting how Raybestos tags the same master cylinder across different product families.
