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) |

Just spent a few minutes looking at PET for 924, 944 and 928 (can't get the 924S PET to download right now)
* The pad spacer is part of the 911 rear suspension arm and not the backing plate. (already knew this) * The 76-79 924, 82-85 944 and all years of the 928 have a backing plate but the pad spacer is part of the backing plate. Hard to tell, but plate looks thicker than 911 plate. * The 88+ 944 did not have a backing plate (or pad spacer), but rather it is part of suspension arm. * All 928 use the same spreader (993 352 073 00) which looks to be a 90 degree pull * All 924/944 use the same spreader (951 352 090 00) which looks to be a side pull My take away from this is ... * The 911 backing plate it too thin to handle loads when the e-brake is engaged. (some people weld the spacer to 911 backing plate, some weld it to the 914 rear suspension arm) * Backing plates for the 924 and 928 were made thicker so they can incorporate the pad spacer and can cary the braking load?? * Some later cars did away with the backing plate and incorporated it into the rear axle casting. * Backing plates between models look to be significantly different. Not sure how much if any swapping can happen. * Would the 924/944 spreader work better as it is a side pull and that might line up better with the stock 914 e-brake setup since if I remember correctly the rear 914 e-brake is a side pull and not a 90 degree pull? Could this mean no need for a bellcrank if you use the 924/944 spreader, but just a short custom cable to bridge between the spreader and the stock 914 cable? |
