Actually I have a drawing of the rear brakes, from years ago when I first took things apart.

I was talking to a friend who is a former mechanic, and he suggested that it might be a problem in the master cylinder. I told him that along with the other symptoms, I had noticed that the brake pedal only went down about an inch before stopping, and he thought that something might be preventing fluid from returning to the master cylinder. And this is a dual master cylinder, so it might only affect the rear brakes.

I am currently digging back in to a 1953 3800 (one ton) with a nine foot bed. I've owned it since 1979, and drove it until 1982 (or so). My wife got me involved in restoring it back in 2002, got the body removed and the frame redone, then things came up. Now I am retired and starting again. If anyone is interested I have photos on Imagur ( https://timwhiteblues.imgur.com/ ). I live way back in the woods in the Ozarks on 40 acres at the end of a 2 1/2 mile private road.
