I think I've come up with a totaly new way to hook up 911 parking brakes. It involves making up longer hybrid cables.
It's not complex, doesn't cost tons, and is about as straight forward as possible. It functions exactly as intended in the 911. Here is a teaser photo; (IMG:http://www.performanceforum.com/wesvann/914a/my-rear-brake/b-mrb1.jpg) Here is a link to my write-up on how I did it (it's a preliminary write-up). hybrid cables Wes (can somebody please find me the photo that I've seen on this site where somebody used a cable end block at the parking brake lever that had set screws) |

Another thought on your idea........I don't have an arm here to look at but is there enough room to cut the arm (notch it) and weld a tube in its place with a straight shot to the mechanism? Also, I'm not sure but I'll look the next time my car is on the rack but there might be header interference with the cable out away from the arm...it's very close on a 6. Might need a tight 90 deg there.
You can draw a sketch of exactly what you want and send it to Terry cable and they will manufacture the cable perfectly as you like. |

For you bell crank types, Wes came up with a very clever solution which employs a compound bell crank that provides opposing actions. He claims it's a bit too complex but, I disagree and think it's a unique solution and it allows the use of the stock e-brake cables. Wes, can you post some photos of this? The one funamental problem with the 911 e-brake is getting a nice straight shot at the actuator. All the solutions place the cable at a slight angle; I don't know for sure how much of a real issue this is (perhaps none) but it "seems" less than ideal. Short of modifying the trailing arm, you're pretty much stuck with this as is. Wilhelm, do you have a close photo of that 928 brake shoe spreader? Seems like it would simplify things quite a bit.
