Hurst Roll Control
 

How do i install a hurst roll control in a 91 Lx. The instructions do not include a drawing of my brake system. I would like to know what anyone that installed this on your car how you set it up.

It's not as straight forward as you would think, but it's not to difficult either. You need to do a bit of extra plumbing as each of the two pistons in the master cylinder feeds one front and one rear. It's been a while since I did it (last season) so I'll have to dig up the schematics. Might even be able to get you a picture or too. If you plan on using their shift handle with thumb button, do yourself a favor. Get a grommet kit from your local hardware store and put a small grommet in the top of the boot, then pass the wires through the grommet. If you make the two wires of unequal length and put bullit connectors on them you can pull them through the grommet and then unscrew the handle real easy when you need to do repairs....

I heard that someone plugged the third line from the master cylinder and then "T" the line that goes to the right front after the proportioning block or whatever that thing is. I was planning using my own swtich or a shirt knob with the button.

Plug the port on the bottom rear of the master cylinder. This line becomes teed with the line from the bottom front of the proportioning block. Fabricate a new line to connect the Tee to the bottom front port of the proportioning block. BTW that grommet trick works well whatever shift knob you use and keeps the wires from being chewed up between the boot and the shifter…..
