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. |

The PO installed it before I got the car, so didn't do the fabricationwork myself. It's a handbrake setup from a MK2 VW Golf ( Rabbit), which uses cables of the same length to overcome the exact problem as described above :-) I plan on using a MK2 plastic handbrake cover instead of the leather thing that's you can see in the picture. This would make it look close to factory made I think.
These's many MK2 Golf parts on my car; the front grill ( water cooled car, you can see the ugly pipes in my interior,.. not part of a rollcage,.. they are gone now.), VDO guages, Handbrake and even the engine that was in was VW Golf ( 16valve 1.8L ) ( Now I'm doing a ej20 Subaru conversion) |
