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) |

Guys, you have to have a firm stop and the shoes have to float. When you apply the parking brake when moving the entire shoe assembly rotates . Picture the rotating drum, the shoes go out and when contact is made the spinning drum tries to rotate the entire shoe assembly. That's why the bottom is not anchored. It's called self energizing and uses the rotation of the drum to help with the braking action. It's supposed to rotate against the stop and why the flimsy sheetmetal backing plate can not be used to stop the rotating force. That method is an accident waiting to happen. You ever wonder why car brake shoes have more material on one side than the other? It's the self energizing effect that shoves the shoe harder against the drum and the driven shoe gets more material to compensate.
If you anchored top and bottom it wouldn't work worth a crap. |
