We are now to offer brake lines from the valve to the wheels for all of our dual master cylinder GM valve applications. These lines are a fit and will take the guesswork out of installing your updated brake system. You will wind up with a much nicer looking installation and cleaner underhood appearance as a result! In addition to offering the lines as sets, all of our '55-'57 brake kits will now include lines.
Image 1a: The stock single 1/4" brake line from the master cylinder feeds down the firewall, under the steering box and connects to the brass junction block just behind the driver's side upper control arm. There is a short 3/16" brake line that connects the flexible hose from the driver's wheel cylinder to the junction block. A 1/4" brake line runs across the engine crossmember and connects to the junction block on the side of the frame. Like the driver's side, a short 3/16" brake line connects the flexible hose from the side wheel cylinder to the junction block just behind the side upper control arm. The brake line for the rear brakes runs down the side frame rail and connects to the rear brake hose on the side of the frame.
Image 2a: The original master cylinder is held to the firewall with four studs. These studs are used to mount a late model brake booster PIN 57-132416-1 or a dual master cylinder and valve. On a non-brake system, the upper studs will hold the valve bracket PIN 57-132390-1, the lower studs are used to mount the dual master cylinder, PIN 57-158461-1 for drum brakes or PIN 57-158464-1 for disc brakes.
Image 3: A valve must always be used when installing a dual master cylinder for the system to operate and the full safety features of the dual system. Our PIN 85-132389-1 is a GM style 5-port valve that bolts to the valve bracket using bolt kit PIN 34-198.
Image 4: PIN 57-153297-1 are the short lines that will connect the master cylinder to the valve. For brakes use lines PIN 57-132441-1.
Image 5: The new brake lines connect to the proportioning valve and feed the left and right front wheels and also connect to the original brake line on the side of the car for the rear brakes. The lines are all 3/16" in size for maximum brake They can be used with a stock steering box, a 605, 670 or Delphi steering box or a rack and system. They will clear side mounts or front mounts and small block or big block engines.
Image 6: At the valve, there are three line ends. The large nut screws into the rear of the valve and feeds the rear brakes. The two smaller fittings screw into the valve and feed the left and right front wheels.
Image 7a: The lines for the front brakes are bent to connect to the front brake hoses in the stock location. Two lines are now run to the side of the frame; one for the right front wheel and the other for the rear brakes. The line for the rear brakes includes an inverted flare coupler that allows the new line to be connected to the factory line for the rear brakes.
Image 8: The new lines run across the back side of the front engine crossmember. Once our engine is installed, the lines will be just about invisible!
