If your brake pedal sinks to the floor at a stoplight, your master cylinder is bypassing internally. This is the most critical safety component in your vehicle. At Old Car Parts NW, we stock authentic NOS (New Old Stock) and NORS (New Old Replacement Stock) Master Cylinders from trusted USA brands like Wagner Lockheed, Bendix, and Raybestos.
Single vs. Dual Reservoir
Single Jar (Fruit Jar): The standard for pre-1967 vehicles. We stock the correct iron castings for concours restorations. Dual Reservoir: Standard on 1967+ cars for safety (separate front/rear circuits).
Quality Castings: Our units are often USA-made iron, avoiding the pitting and porosity issues common in cheap modern aluminum replacements.
