Jul 21st, 2025 | | | | Joined: Jun 2006 Posts: 687 Shop Shark | | Shop Shark Joined: Jun 2006 Posts: 687 | Having a problem with my brake job. I think I have found a cure but wanted to pic a brain or two before I act on my guess.
The 1942 1/2 ton and most other cars with rear drum brakes have a breake spreader bar that pushes against the front shoe when the brake is set.
The bar seems to be too long when the shoes are in place and wont let the shoes come together enough to install the drum. I have dismantled the shoes and removed the cable from the swing arm thinking maybe the cable was too tight, but still too far apart. With the adjusters screwed all the way in and the cable disconnected still to far apart.I fact the shoes are a full 3/8 of an inch from touching the adjusters and the drum wont fit arround the shoes. If I remove the spreader bar they come together and the drum will fit. The shoes I installed are identical to the ones I removed.
Here is what I think. At some point in the trucks life some one could not get the emergency brake to hold so they straightened the spreader bar a little for more travel. They shoud have adjusted the brakes and cable.
Has anyone had this experience? HELLLLP!!!!
Before I rebend the bar I am hoping for a reply. None of the parts books show a picture of the bar and I have no data to support my theory. :confused:

These parts were all together and functioning before you started this job correct? | | | | | Joined: Dec 2005 Posts: 324 Member | | Member Joined: Dec 2005 Posts: 324 | Be sure the spreader bar is in contact with only one shoe, the other end only in contact with the lever pined to the other shoe. Also check that the noches (spell) fit the shoe...... aaa the shoe and lever fit into the end noch on the spreader bar.

I took the spreader bar (rod if you will) and shortened it about 1/4 inch by bending the end that attached to the front shoe and it did the trick. It was already bent (from the factory) I just bent it a little more.
Anyway, the truck will now stop on a dime and give change. No pull or pulse.
I realy think the mechanic before me bent the bar instead of tightening the brakes and cables to get more emergency brake action.
Thanks for the posts. James
