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) |

This is what AndyS is talking about when he comments on the "lever" design I did. He knew about it due to my sending him photos for discussion.
Prior to working up the method in my write-up, I did a couple designs that involved a lever action, which would still work the "push and pull" on the 911 spreaders. I guess it's worth posting. (sorry about the first photo not being focused very well) (Andy also voiced consern on the "cable method" being too close to the exhaust) (IMG:http://www.performanceforum.com/wesvann/914a/my-rear-brake/lever1.jpg) In order to figure out how it works you first off have to know that the allen head bolts are shoulder bolts and work as pivot points. Then you have to know that the green arrow points to a "floating" pivot point. It isn't attached to anything other that the arms and can move in space. The last thing is that the pivot point pointed to by the red arrow would be attached to the trailing arm. It's a "fixed" pivot point. There is a short section of stainless steel tube that pushed on one of the spreaders, while a 1/4" thread rod pulls on the other. Ya, it would work, but I just thought there had to be a less complex way to do it. That black tie-wrap is just holding it in place for the photo. The following photos are showing the linkage on the garage floor, just to make it more clear. (IMG:http://www.performanceforum.com/wesvann/914a/my-rear-brake/lever2.jpg) (IMG:http://www.performanceforum.com/wesvann/914a/my-rear-brake/lever3.jpg) And the following photo shows the two arms. (IMG:http://www.performanceforum.com/wesvann/914a/my-rear-brake/lever4.jpg) The one on the right fits inside the one on the left. Both arms have a "bearing plate" on the end. The one on the left is what the length of tube bears on and also has a hole that the threaded rod can pass through. The one on the right is what the nut on the threaded rod bears on. Discuss away!!
