My GT - Rally Brake Installation Progress Photos

Here we're trying to duplicate the Porsche factory Rally Brake System modifications implemented in their rally race cars. Bernie started to work on this phase of the project as we continue with our research. More photos and details will be uploaded as progress is made.

Our friend Benno in Germany came across some of the same obstacles and challenges that we're currently discovering. Here is what Benno did for his own 914-6 GT Rally Parking Brake installation https://pbase.com/9146gt/the9146gt_atshop2014_install_rally_parking_brake_benno_de ~ Thanks again for the reference photos Benno!

Hi Armando-

So, it looks like I have one end of the puzzle solved. Taking Armin measurements I cut down a long 914 E-brake cable (Rt. Side Cable), bored our the end fitting and re-swedged the cable housing into the end fitting. Next I cut the threaded end off of a 911 E-brake cable and bored the cable out of it, A real bitch by the way. Now we have a cable housing of 1150 mm and a cable with the overall length of 1355 mm with the correct ends on it.

Next step was to cut off the E-brake cable holding bracket from the stock 914 control arm, modify it and tack weld it in line with the 911 E-brake assembly. It looks pretty good, I checked it on your car and it’s very close but the final cable length will need to be determined when we have an E-brake lever. There was a lot of “tweaking on the control arm to get the bracket to fit but it all comes tighter with all factory parts, even the cable housing retaining clip on the control arm.

Sorry it’s not as crude as the sample photos from the C.....r car, but I think I can make it look more cobbled up than it is, but it will take extra time and $$$$$$.

Hallo Benno! Yes indeed, it has been a long time.

Please, email me AJSERRANO@MSN.COM photos of your set-up and also of your car, love to see those too! I'm trying to follow how the Porsche factory modified the rally braking system in my own GT project. As you know, there is more than one way to do this... : )

Thank you for the post.

Hi Armando,

some years ago, we've had an email conversation regarding the e-brake setup. In the meantime I've finished my setup. If your interested, I can provide you some pictures of my modified rear trailing arms.

Hi Armando-

I modified a rear control arm this afternoon and got the E-Brake backing plate to fit. It required the removal of a mounting ear (Red Circle) and further grinding back the boss for the backing plate (Black Circles)http://www.pbase.com/9146gt/image/161625359 not too big of a deal, a couple of hours per side and we should be good.

I ordered a pair of E-brake cables from a 70’ 911 and we’ll see how it all comes together. I put the test arm photos as attachmentshttp://www.pbase.com/9146gt/image/161625357
