Brakes are set up as per [richpin] video. They appear to be spongy. But they stop the, but not in a skid. What do you think?? Thanks again Dwight
 
I have never heard of the richpin video. "Spongy" is usually a term that I associate with air in the lines of a hydraulic brake system. Do you have hydraulic brakes, and if so what are they.

No! richpin is on Youtub and he has some very good Videos. Maybe I think the truck should come to a screeching halt, and that is not the way it works.

If I remember correctly there is a softer feeling to the mechanical brakes. Do you have access to another car that you could test drive? Do you have a link to the youtub video?

whenever I have felt "spongy" mechanical brakes I have found one, two or all of the following: bent brake rods; brake shoes that are not centered; wheels that are not adjusted equally.
 
Yes, I used the board. The brakes were rebuilt about 12 years ago and the truck has not been used since then. Also I have used YouTube for some Info. Unless some one comes up with a better Idea from doing each wheel I may give that a try.. Thanks
 
check the wear pattern on the shoes. If they're not making full contact, they were not centered when they were "rebuilt", a term misused as much as "restored". When the shoe only makes partial contact at the ends opposite the wedge or cam, the brakes feel spongy because as you press the brakes, the non contacting part of the shoe bends toward the drum. Good A brakes feel firm and lock up when you press the pedal firmly.
 
I've got a '30 ccpu and have been front to back with sweat and new parts on the same problem. The brakes felt like they hit firmly but not enough braking action. I finally figured out that the cross arm was bottoming out on the trailing radius rods connection to the u-joint cover. New motor mounts and ****** mount raised it to give good clearance and full braking action.
 
I have found that brakes on a Model A are a 1+1+1 = They work. Everything in good working order is essential to good brakes. Any break or weakness in the chain of components will result in poor braking.

One critical component that I have found essential to good braking is the original woven brake linings. The modern linings and steel drums are not a good solution IMO. Once I replaced the modern linings on my coupe with original woven linings the difference was night and day. I can now lock up all 4 wheels if need be.

Step back and do a full inspection and look for weak links and then start from there.
