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'm glad I started this sting)
Here's a bunch of thoughts and questions on the 944 spreader method (the "wilhelm" method). In the stock configuration, does the spreader assembly just float free, held in compression by the shoes? Looking back at the factory diagram posted by Wilhelm, what is item 23? What function does it serve? When Clay says that the backing plate supports the cable, to be specific, is he taking about the "dead-head" anchoring of the sheathing. I'm pretty sure this is what he is saying due to sheathing having to be fixed in order for this to work. This is significant due to the fact that it wouldn't be required if a bell-crank was used (as in some of the other methods. You couldn't use the VW bus cable due to it's end not being compatable. There just isn't any reason for it, other than being longer. I have to assume that there is somthing like the 40mm spacer at the spreader, as there is on the 911, welded to the trailing arm. Here is how I view it being done (if possible); Use the early 911 backing plate and cut out the minimum to allow the 944 spreader to fit. Mount the shoes and spreader. Fab up and weld in place the equivalent bracket as the 40mm one used in 911 installations. A hole would be needed for clearance for the "pull rod". Use a bell-crank as shown in prior posts. Connect the bell-crank to the spreader with a threaded rod and clevis. (NOT CABLE) Remove and relocate (weld) the bracket that holds the stock 914 cable, directing it toward the bell-crank. Attach the end of the stock 914 cable to the bell-crank using an "extension" arm as shown in prior posts, if required. If all this works, I really like the solution. The fabrication work isn't that complicated and it would provide the most clearance from things like the exhaust piping. I really wish that there was a 944 around here that I could take the rotors off and check it out, take measurements, and such. Wes |
