Valve Notes:

For use on 1966 factory drum cars.

This is the distribution block that is mounted below the single master cylinder which feeds fluid to all four wheels. 1966 cars have a 1/4" master cylinder line and a 1/4" front to rear line. This block is not correct for 1964-65, these cars had a 3/16" front to rear brake line which makes the rear port smaller. This is an exact reproduction down to every detail. It is the correct size shape and thickness, made of brass with a phosphate bracket. These blocks are often missing, thrown away, or stripped.

1964-66 cars all had a single master cylinder with drum brakes. There was no proportional valve and no disc brakes available in these years. The tee block that mounted to the frame served as the distribution block. When converting to disc brakes, the system will need a prop. valve. This aftermarket valve mounts on the frame similar to the 64-66 cars or on a bracket below the master.

1967-70 cars all had a dual master cylinder and also 1967 was the first year for disc brakes. If the car had drum brakes, there was a distribution block with a built-in brake warning switch. If the car had factory disc brakes, it used the drum dist. block in conjunction with a disc brake hold off valve, which made the disc cars a 2 part valve. For disc brake conversions, replacement aftermarket 1 piece valves are available, see listing
