I'm looking for a complete parking brake set up for a 46 chevy 2 ton truck. Everything has been removed from mine, except the bracket on the transmission. I'm not sure what all there is and a few pics of how everything is supposed to look would be appreciated. Thank you
Itook this pic. I'm not very familiar with what these trucks had originally. I really haven't invested too much time in researching everything. I just don't have the time to spare. Basically, I know enough to be dangerous.. lol
I did some further digging in the GM Heritage site and based on what I found 1946 Chevrolet Truck "brake" data, your parking brake setup consisted of the transmission mounted hand brake lever assembly that actuated the rear axle mounted drum brake shoes through a rod and cable system. See the below screen shots taken from the page indicated.
I thought you may have been describing a "transmission mounted" drive line parking brake setup like is found on later AD series trucks. My apologies for getting this wrong. Turns out there was a "drive line" mounted parking brake setup, but was only an RPO for "buses" so doesn't apply to your 2 Ton.
For further diagrams and part number info, you should look through this 1941 Shop Manual which I think remained the same through 1946 due to no model changes during WWII. You may also want to look at Chevy Master Parts List 1929-54 which lists parts and some diagrams that relate to your '46 parking brake needs.
Hope this info is helpful.

I'd agree with what Dan said. Your picture doesn't' show any evidence of an attachment point for the brake drum on the transmission output shaft yoke. Check the pics on this post for what the transmission mounted brake would look like.
Check your rear brake backing plates for signs of a lever or cable attachment point which would indicate wheel mounted parking brakes.

The brake lever is mechanically connected to both rear brake housings by rods and levers. On the side of the transmission, the brake lever attaches to a rod that travels straight back towards the rear of the truck. At the cross member that has the hanger bearing for the driveline, there is a lever mounted that connects this rod, and to two separate rods on each side of the truck to connect to the flexible cables that run down to each side of the axle. the other end of the flexible cables ties into the actuator arm that sticks out of the brake drum. There is also a return spring that is connected to the central lever that hooks via a long rod into the crossmember just in front of the rear axle. There is also a support loop to keep the long rod between the transmission and the central lever from sagging excessively.
Pulling the lever back in the cab causes the rods under the truck to move forward, pulling on the cables to each wheel and applying the brake shoes to the drum. Adjustment is accomplished by changing the length of the various rods by turning a clevis on a threaded portion of the rod. The other end of the rods have a fixed clevis. Hopefully these photos help, I didn't want to get dirty crawling on the floor when I took them a few minutes ago.
The brackets of the 4th pic that hold the cables on both frame rails are still there, but i think everything else is gone. I'll take a few more pics tomorrow and do some investigating. Thank you for all of the responses, it's super helpful.
