Installation notes
Check the centre-to-centre distance of the mounting holes before fitting (3-1/4 inch standard). Ensure at least 1/2 inch free pedal travel before the push rod contacts the cylinder piston. Fill with heavy-duty brake fluid conforming to SAE-70-R3 specification to 1/2 inch below the filler hole rim. Bleed the brake system thoroughly after installation.
Compatibility
Please note: there are different master cylinder versions with varying mounting hole configurations. Some versions have two threaded mounting holes at the front and one through-hole at the rear, others have one threaded hole and one through-hole. Check your existing cylinder before ordering.
Historical context
The master brake cylinder was originally supplied by Lockheed Wagner as OEM supplier for the WWII jeeps and early post-war models. This type of single master cylinder was standard on military vehicles until the introduction of dual-reservoir systems for civilian models.
