Here's why most modern cars have the ebrake handle in the middle of the car -- it's so the cables running to the wheels have identical length and path. How do I know? Here's the anecdote:
For the last year, I've been struggling with my ebrake system. The right caliper just wouldn't clamp as tightly as the left. I've got rebuilt calipers, new pads, new cables, proper clearance, but no worky. Finally found out why. It's the internal drag of the actuation cables. The passenger-side cable is substantially longer than the driver side. Also, the right-side cable has 3 right-angle bends vs the left-side cable with none. This results in so much internal friction that the cable just binds solid when it's pulled. I was able to improve the situation somewhat by lubricating the cable. Still not perfect, but much better. |

I've been considering just putting a line lock in place like I have on my Samurai. It just goes in line with the existing brake lines where they exit the master cylinder. Has a switch that turns on a one way valve. Flip the switch, give the brakes one good pump and all 4 wheels are locked.
