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 think it dawned on me why Clay said that the 944 spreader is "attached" to the backing plate.
I think it's that the backing plate prevents the spreader from being pulled outward by the cable. (IMG:http://www.performanceforum.com/wesvann/914a/my-rear-brake/944spreader.jpg) The green line would be the backing plate. The spreader would "wipe" across the backing plate a small amount. It may also help answer that that item 23 is. If this isn't the case, then function wise, it's doing pretty much what the "single spreader / pull only" method does. It would dig the brake shoes into the backing plate with the force applied by the pull cable. Fab'ing up this bearing plate in the correct location would be difficult (at least for me) and may be why Clay ruled it out. Wes |

I think you are correct here. Although I have not looked at the rear brakes of a 944 in a long time I think the spreader actually rests/is pulled against the backing plate nearer the ends of the spreader. The curved ends provide a pivot that is stable and would not move around much and have good leverage. The green lines here would be the backing plate. The opening in the backing plate for the cable would also have top be big enough to allow the nub on the spreader to clear. I do like the idea of using the 944 spreader with the bell crank method already used by some. Anyone know if real early 911 (66-68 with short wheelbase) rear parking brakes are any different than the rest? I have what I believe to be a set of 911 short rear trailing arms with brakes in my spare parts. Great thread Jim |
