I just got a '57 Chevy rear end installed in our '50 tin woody wagon. Many thanks to Tom Parsons and all the other ChevyTalk folks that provided guidance to me on this. What a fabulous collective brain trust we have here!

I'm now trying to figure out how to connect up the parking brake. The brake cable on the '57 is one continuous loop, not two separate cables as in '49 through '54. I also do not have the pulleys and cable guides that the '57 used. The '57 brake cable loop isn't long enough to reach up to the '50 parking brake hardware.

How have other folks made this hookup? I'm considering mayb going to a MICO electric brake mechanism if I can't make this setup work without too much effort.

Any ideas folks? Thanks for any suggestions!

In NYS, the electric parking brake set up will not pass state inspection.

Hey Mike, I did this same swap a year ago when I installed a 3 speed overdrive and 56 Chevy rear in my 50 Fleetline. It took me way longer than expected due to the domino effect of changes that happens when you start modifying! And that included the parking brake.
I was already running a Lokar floor mounted handle as I have a 54 Corvette exhaust manifold that prevents using the stock park brake set up. Anyway, I ended up moving the handle alongside the drivers side trans tunnel, and fabricating the rest to replicate the 55-57 Chevy lever mechanism. Basically it's an angled box that mounts to the floor brace with a lever that unites the cable (via the stock 57 Chevy cable linkage adjuster) and a rod with heim joints to the handle. It was a lot of trial and error in tight quarters. as I also have an underfloor dual master and booster.
For the rear end swap, I found I had to move my leaf spring mounts outboard to get the rearend pads lined up nicely. I made brackets to hold the brake cables that used the spring mount holes. I'll try and find some pics.

I have a '57 rear end under my '51 Chevy and it is hooked up to the stock parking brake linkage. This retrofit took place before I bought the car. So I can only speculate on what they did. My hunch is they may have pulled the stock cables and retrofit them to the '57 rear end. The mechanics for activation I believe is the same between axles. Someone may chime in with a different opinion. Good luck with your project.

Mike I think I told you wrong in the email.
I think is re-used the stock 51 cables between the lever and backing plates.

But again, as I originally suggested, since your engine is a 261 (same style as a 216 or 235), I would really prefer to stay with the stock style em brk setup. Those really worked just fine.

One little detail I learned is that the Huck brake cables on the '49 and '50 are different from the cables on the Bendix brakes from '52 on, so they don't hook up to the shoes and they also have different brackets on the backing plates.

EXCELLENT point. I totally failed to register that you had the Huck brakes. That completely changes my thoughts about re-using the 50 cables. DUH!!!!!!!!!!!!

As many people here that have replaced their 51-54 rears would surely have em brk cables that you can acquire.

While I used a 9” Fxxd rear behind the 454 in my 53, the park brake cable is similar to what you described. You don't have the big X member the convertible has but you might make something that will connect to your transmission cross member.

The bottom line is a little creativity can go a long way.

One other thing that may help. If you can find them at your local electrical supply, the strand splices make neat and clean way to shorten the loop if needed.

I've got a 56 rear in my 51. When I did the T5 swap I had to rework the e-brake. I retrofitted the stock e-brake fulcrum parts onto the new crossmember. I had to lengthen the rod from the handle back to the fulcrum as the crossmember sits farther back.

for cables, I went to my local U-Pull-It and found cables that are the right length. The ones I found were from a truck and they had several short ones with a bracket to join them together...I got the cables and the brackets and pieced together what length I needed.

My plan is to make my own rear loop cable, fulcrum, and use either a Chevy venture push-on-push-off pedal (installed in 2015 but not connected) or more likely I’m going to encase the original handle in a tube and fabricate a spring and tooth for the gear, with a connection to an “upper cable” common in a Malibu or corolla or something similar that will operate the fulcrum lever. The fabricated cable for the back will be 1957 style probably with an actual 57 yoke or whatever the part is called that the cable goes through where it meets the “upper cable”

Basically copying 1957
