These standard master cylinders are 100% machined billet aluminum for extra strength compared to cast aluminum competitors. They have standard 2-1/4" pattern used by most brake companies so they will mount to most pedal assemblies and firewalls. The mounting flange can rotate to be a vertical bolt pattern or horizontal pattern. Uses DOT 3, DOT 4 or DOT 5.1 brake fluid. The outlet is tapped for standard 1/8" NPT fittings.
