BLK241 1962-64 A, B, C-body Distribution Block - Polara / Dart / Coronet / Fury / Belvedere
Tee Block - Brass 5 Port Valve Front Drum - Rear Drum Dual Master Conversion
Brass $35.00
Valve Notes:
For use on 1962-64 cars converting to dual master cylinder or disc brakes.
This is the distribution block that is mounted below the single master cylinder which feeds fluid to all four wheels. This block is designed to replace the single master cylinder block in the stock location. For the first time, cars can be upgraded to dual master cylinders or disc brakes while keeping the factory appearance. This block mounts in the same location as the old block and allows you to reuse most existing brake lines.
Dual Master - If you are converting to dual master cylinder leaving the drum brakes, simply mount this block in the same location, hook up the right and left front brake lines and hook up the front to rear. Two ports are left - You will have to make 2 master cylinder lines both in 3/16". This block makes conversion a snap.
Disc Brakes - If you are converting to disc brakes with dual master, simply mount this block in the same location, hook up the right and left front brake lines and hook up the front to rear. The 2 top ports are left - You will have to make 2 master cylinder lines in 3/16". With this block you will need to plumb in an adjustable prop. valve to tune down the pressure to the rear brakes. This valve can be mounted anywhere in the front to rear brake line.
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 after market 1 piece valves are available, see listing.
Just a quick comment here about when discs were first available. I think that C body cars got optional Budd discs in '66 and Imperials in '67. The A body cars (Barracuda at least) had Kelsey Hayes discs available in '65. B body cars got Bendix discs midway through '66 from what I have read.
