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 bought some 911 rear brakes and aluminum arms on samba and ebay. You probably need to know which years you want though. The two sets I have I think are 74 911 and 84+ maybe 944?, thats what I marked on them when they were sold to me. The 74 are straight pull and the 84 are angle pull. The straight pull come out the cavity for the stub axle and the angle pull comes out a angled port in the aluminum arm. The later arms are for a wider wheel. It seems from what everybody has contributed that the deal is to use the 911 backing plate with the notched brake shoes and the 944 spreader or the straight spreader and a neat two piece bellcrank like the one already designed. It won't be long and this could be a kit for the guys that don't fab.
On looking back at wes's thread on the cable/backing plate install, which is GREAT I wonder if you could just use the inner 1/2 of the original 911 rivet style spreader and make it pull only with a simple bellcrank and a rod to the bellcrank and a rod to the stock 914 cable? That way the replacement parts would mostly be early all 911. It sorta looks like the backing plate could be rotated 180 and put the cable and spreader on top maybe not. I found this on the net. The spreader might be called a expanding lock, they also have a support and shoes but I will probably just have mine relined. http://www.bavauto.com/se1.asp?dept_id=168 The angled spreader is called a expanding lock, it's part # 34411163709 it's down the parts list aways. I just called Larry at 20th st in AZ. and told him I wanted early 911 backing plates off of the steel arms and 84 944 expanding lock's and adjusters and even shoes if he has them and he said he didn't have any 924 rear brake parts at the moment but he will call me when he gets them. A guestimate was very reasonable. http://www.20thstreetauto.com/porsche/porscheparts.htm#924 He seemed to have a knowledge of the application we are working on. Seems like a good place to get the small stuff so I won't need to rob the complete arms I have. Added 01/06/09 Ok the guys at 20th st called back. Larry and Mathew. I got early 911 (68?) backing plates off of steel arms, 84/944 shoes, and all attaching hardware with the angled expanders for 140.00 + shipping. That is a little expensive for some but porsches are a little hard to come by in Crawford. At least the part chasing is done for this deal. If you mention my name they know what you are doing. Charlie Wittmer 01/07/09 found another good place to get the parts, it's planetporsche the guys name is Bill Martin They have lots of porsche stuff I originally found them on ebay He had some new shoes and a good 944 cable that I may use with a 944 brake handle. I kinda want the emer.handle in the center. It looks like with a little imagination a bolt on support could be fabbed up and the support could be a drill and tap the arm and mount the support deal for the ones that don't fab. |
