Need a Grassroots drive shaft brake.

The 1964 Jeep Fleetvan I have has 1964 drums up front and calipers/rotors out back that someone cobbled in. The calipers are from the front of some car so there is no way to attach a brake cable.

I've been looking around and the best I could find is a kit for $299, seen below.

I looked a golf cart brakes, but they are hydraulic; go-karts have manual calipers but too small in diameter to have the drive shaft through the center.

What car had discs in the back with an e-brake? If I had one of those calipers I might be able to make up some kind of fixture to mount it to the tranny or drive shaft. The Jeep has a pull handle on the dash that I would like to keep.

Listening to any and all hare brained ideas ......

Thanks for the help, Dan

Alfa Romeo Alfettas had inboard discs in the back, with emergency brake. That's all I've got.

Edit: Wait, that's not all I've got. Buy my '63 Willys and pull any of the parts you like.

The answer, as always: Miata. The cables run the caliper piston in and out. Then there's the Rodeo/Trooper through 1997, those have rear disc and a smaller drum brake inside the rotor 'hat' for the parking brake.

AE92 rear calipers have a built-in cable E-brake mechanism but good luck finding them.

You could look into pinion brake kits meant for rock crawlers..but I doubt they'll be cheaper.

Troopers don't have an internal drum, they have a cable that just actuates the normal pads. I've actually got a brand new rear trooper caliper sitting on my bench that I'm not using.

Oh, and the answer is an old IH truck. Many had driveshaft e brakes.

miata egt mazda6 some nissans hondas, mazda3

Those are drums, my old Dodge had them too. Problem is finding someone that will reline the shoes. Too many bits & parts. I just want to park brake.

Go to NAPA and look at rear calipers, most new ones will have an e-brake cable. I'd imagine you kow somewhere that could make the mounting bracket and a rotor mount, and here is a small rotor http://www.speedwaymotors.com/Emergency-Brake-Replacement-Rotor,44787.html

Look at off road/dune buggy hydraulic set up. Basically just a valve that you close with the brakes applied. Release it and your good to go.

The Escorts that had rear discs, EGT, SR, all mexican, had a simple parking brake included.

First question is - what size piston do you need in those calipers?

It's easy to fit Miata calipers. Here's the bracket I used on the MG, minus two holes that were used to bolt the caliper on. I just slid this over the axle tube and welded it on.

Or just put the original drum brakes back on.

high-spec 87 Chrysler FWD turbo cars (Daytona, Lebaron, Shelby CSX) had the external e-brake rear caliper before they moved to the internal drum solution (because the external e-brakes didn't work too well)

That's all I got.

the late 80's maybe early 90's subarus with rear discs had a simple E brake built into them as well. I also have at home a wilwood spot brake, its a mechanical caliper that you can use with pretty much any stock e brake level or pedal and clamp on any thin rotor. I'd go to a junkyard and pull a thin brake rotor off a motorcycle or something and make a plate to bolt it to your yoke. The calipers run about $60-70. More than a junkyard caliper but its an easy solution thats not unreasonably expensive.

Both of my newer SAABs have the internal ebrake drum\disk setup.

Can you remember any mototcycles having a manual caliper up front?

What rear is in the Jeep now? Is it the original with the rear disks cobbled to it, or was something else swapped on there? And what's the rotor thickness.

The late '90's Cobra Mustangs use a caliper setup for a mechanical parking brake. Not sure if the T-birds did or not.

GM had one in the late '70's/early '80's on the Riv & Eldorado. That's what most of the current muscle car rear disc conversion kits use. I'm not a fan of their design.

Wilwood has some small mechanical calipers in their catalog. Depending on your rotor thickness a pair of them added to the existing rear disk setup might do the trick.

no motorcycle at crazy ray's do, that I found, but I did find a few dirtbikes and mopeds. Also many 4 wheelers do as well.

Modern UPS trucks have them. Wherever those chassis go to die is the place.

I don't NEED a parking brake, I know this guy .....

I would sleep better at night knowing it was safe to drive.

In reply to 914Driver: That mechanical caliper in your picture looks like it came from a forklift.

In reply to HappyAndy:

It also looks damn near identical to the wilwood spot caliper that I and at least one other person have mentioned.

Which can be found on a lot of go karts, 4 wheelers, etc. Other small applications using a mechanical brake.

apparently the working parking brake thing went right over my head yesterday..... came out and the truck was not there. it was down the driveway in a hole with significantly more destroyed tailgate and bumper

I meant to post '92-'97 had an internal drum brake on the rear, mine does. '98-up does too, IIRC, but Isuzu made a fair number of running drivetrain changes after '98.

There's definitely lots of forklifts with pinion mounted parking brakes. Cat used them back when I was with the local dealer.
