for those that have done 911 ebrake conversion question Options

[rfuerst911sc]

I am in the process of converting to 911 ebrakes. I have done a search and there is lot's of good info and pics. I have done the grinding to get the ebrake hardware to fit the 914 hub. I have it all mounted. I have fabbed and welded the stationary piece that the ebrakes have to stop against. However what I can't figure out from the pics is what are the rough dimensions of the transition/bell crank piece? I have moved the OEM cable mounts so I know where the cable will end and I have left room for the swing arm to do its thing but my head is stuck on this bellcrank. Can anyone give me the dimensions of the pieces they fabbed? And what did you use for raw stock? I am brain dead on figuring this out (IMG:style_emoticons/default/dry.gif)

The problem i have with a bellcrank is that you only pull ONE side of the spreaders. That makes the shoes contact the drum unevenly.

Rich, Wes, and I have been working on a way to use the stock cables and still retain the ability to use both spreaders, but it is not finished.

No it does not make the shoes contact the drum unevenly. Who told you that?

On the 911 setup, the 911 cable sheath applies force to one spreader "bow-tie" and the cable itself pulls on the other spreader "bow-tie".

There is no real good way to support the 911 cables as they would run into exhaust if routed directly away from the e-brakes ala 911. This has been one of the major problems over the years when attempting to go 911 e-brakes.

The bell-crank is just a different approach and allows one to use factory 914 e-brake cables. It's a straight-forward simple solution.

Good luck. In the mean time, we will all be USING our e-brakes.

I have been using a 911 style e-brake for 2 years now. I am the one who came up with the idea of putting the backing plate on rotated 90 degrees downward. So I know a LITTLE bit about this subject.

And yes, it DOES pull unevenly. No one TOLD me that, I setup my park brake on my car 2 years ago and explored what you are doing now. I found that it needs BOTH spreaders to work properly.

But it is your car. Do what you want. You will hate it when that bellcrank gets crap clogged in the pivot and you can't get your park brake off. Wes Hildreth found this out on Mike Floyd's orange 74 2.0. Mike had to beat the bellcrank with a hammer to get it to release. This is not hearsay. I saw the results with my own eyes.

I would NOT use a bellcrank.
