Drive shaft parking brake solution

[j-c-c]

So i'm building a rear drive IRS street/track car. I'm ditching the rear wheel rotor internal parking brake set-up. The rear end will be a Quick change. This will NOT be an emergency brake, but for peace of mind when on the street, I would like a parking brake. Drive shaft seems best solution. I'm thinking a 6-8"d Ti solid rotor 3/16" to 1/4", but securely mounting it to the rear yoke area, is my problem. Anyone have any suggestions or seen anything that was simple in a similar application? I'm think a mechanical almost go kart style caliper. Using an existing wheel rotor is not an option for me.

The rear disc brakes on my Dodge Omni are from a 1988 Daytona.

The parking brake is mechanical activation on the caliper piston.

I wonder if many other calipers use this simple system??

Thanks

Yeah, Sure, a lot of euro stuff has that.
Just this week, my kid put on rear calipers from a VW on a 9in Ford with Explorer discs. The caliper is aluminum with a smart cable setup for the E-brake.
Op is probably using wilwoods or something even lighter and stronger.

Right on!!

I appreciate the input.

I'm not familiar with Euro stuff at all.

Chrysler went with internal shoes so that's what most swap.

I still like the first design better.

Thanks

Thanks, that link was helpful, waiting for their response.

Plenty of cadillacs and corvettes had rear disc brakes with mechanical parking brake levers, so did quite a few camaros, until the late 90's, when they switched to drum-in-rotor parking brakes. Dunno about other makes/models.

Another option that is used in medium duty trucks with hydraulic brakes is a Mico lock. You push on the brake pedal, move the lever, then release the foot brake. It traps the hydraulic pressure in the lines until you release the lever. It's widely used on medium duty trucks, so it does work. Obviously the brake system can't have any leaks, otherwise the pressure bleeds off. When I was working on trucks, they'd hold pressure for weeks or months in normal use, even though they're labeled as a supplement to parking brakes.

i have a turbo 475 transmission from a motorhome that has a E-brake built on to the tail housing. Maybe that is what you are looking for ?

You just invented a 1955 Studebaker medium duty truck parking brake.
