Seeking advice on drive shaft ebrake solution

[kmseddon]

Hello community of wise experts - First off, I hope you all have a safe and enjoyable Fourth of July holiday with your families. Considering where the world was a year ago, we have much to be thankful for. Second, thank you to all who put the time and effort into this blog helping us first time builders along the way.

I need some wisdom from the group on how to connect up the caliper for my drive shaft ebrake set up. I will be running a 351 Windsor married to a one of the new TKX transmissions. I have an IRS rear, and wanted to stay with the classic look of 15" wheels. I've already worked through how to get the Wilwoods calipers on the rear brakes and the got Wilwood to paint the calipers in Gulf Livery orange (Wilwood calls it Competition Orange I've got the color code if anyone needs it). With the smaller 15" wheel I don't have room for the ebrake on the rear rotors like the assembly manual calls for.

So I installed a disk and caliper on the drive shaft. Anybody else done this before? I'm looking for clever ways to mount the spring/hardware to the chassis so that the cable goes OVER the round frame tube and can be connected to the stock ebrake handle.

Here are some photos of what I have so far. I just need to figure out how to connect the ebrake handle to the caliper while clearing the spinning disk on the drive shaft.

Thank you in advance for your time and expertise.

Is this a "kit" made for this application or a universal brake? Do you have fabrication skills including welding and the equipment to manufacture the small parts you'll need?

Hard to say from a few photos but you may want to have a custom cable made to your specs and fabricate a bracket to hold the cable end. Here's one company that can handle custom cables: http://www.controlcables.com/parking-brake-cables-2/

I took a different approach to a parking brake when running large rotors with 15" wheels. I used a block valve in my rear brake line to hold pressure on the rear calipers. Many of the airplanes I've flown have a similar parking brake. I used one of these to make installation simple: https://www.speedwaymotors.com/Speedway-Park-Lok-Universal-Hydraulic-Parking-Brake-Line-Lock,1970.html

Your system will also work as an e-brake but is more complex and heavier than mine. If you have fabrication skills and can weld, you can do most anything required to make a custom parking brake. If not, my hydraulic system can be installed by anyone with moderate mechanical skills.

Have fun with your build.

I did not see any mention of a drive shaft loop. Would the Metco loop provide a surface to fab a mount?

What you have is Gordon Levy's pinion parking brake kit. I worked with him to develop the 15" wheel brake and parking brake kit he sells. See my build thread. It was the prototype a few years ago. If you search the forum I think I have a thread or two I started showing this in more detail.

This is my brake kit. You you email me I have some more detailed pics I can send you that Duke sent me on the park brake setup.

Here, I posted them online if this helps anyone else too. The bracket is just a quick piece I built in a few minutes using some scrap sheet metal I had laying around. I think I cut up a cereal box for a quick template, then transferred it to metal.

When I did my 2015 IRS retrofit I needed to shorten the inner P-brake cable. Just to let you know, I cut out a chunk, overlapped the ends and used three cable clamps from Home Depot. I was concerned they would slip but figured if they did I would at least have my needed measurements to have a new cable made. 3 yrs of use and they did not slip.
