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) |

I agree with what Richard is saying.
Think of the shoes, adjuster and spreader as an assembly that is free to float. To play with numbers: When you first pull on the parking brake, each shoe moves away from the block an equal 1/8". You then push the car forward, the assembly would rotate until one of the shoes came in contact with the block. Then you push the car rearward, the assembly would rotate in the other direction and the other shoe would come in contact with the block. Using those numbers, if you rocked the car back and forth, the spreader would move 1/4". If you yank on the parking brake while the car is in motion, one of the shoes is going to hammer into the block!!! All of the rotational force gets transfered through that small contact surface on ONE shoe!!!!! Wes |
