A.B.S. Brakes Installation - Franken-Brakes

For those not familiar with AN brake fittings, this what it look like in action on the driver side and passenger side. Both shots show the inside of the Roadster Shop chassis where the line goes into a bung that is welded into the frame that was threaded with 1/8-inch NPT to eliminate lines hanging under the frame and making things much tidier.

Same thing at the rear with the flex line at the right going into a 90-degree AN to 1/8-inch NPT fitting and then into the frame and is basically the same on the other side except with 3/16-inch hard line.

Patience, grasshopper! This is a good example of how clean your lines can look with a little practice and planning. The guys over at ABS whip this stuff out pretty quick, but they do it every day.

Residual valves! Don't forget these if your master cylinder is mounted under the floor. They prevent fluid from draining back into the master cylinder since the master has been mounted in the same plane as the calipers.

The decision was made to mount the pump on the outside of the Roadster Shop frame just opposite of the pedal assembly and master cylinder unit.

The "block" to the right of the pump is an optional remote mount for the accumulator for real tight places, otherwise the accumulator would've hit the frame and the floor.

The pump assembly has a built-in high-pressure safety switch to keep things in control.

Here is our preassembly to show that the system works properly. Since we need the body on the chassis to mount the remote fill permanently, a temporary one was set up along with hooking up some power to the unit.

With the brakes bled and everything hooked up and ready to go we had 1900 psi at the pump! Normally, the accumulator would mount where the pressure gauge is.

At the six-piston Wilwood calipers up front, we found 1400 psi with the applied.

And at the four-piston Wilwood calipers in the rear, we got about 1400 psi, as well.
