Charlie, pull your front drums and inspect them and the shoes for rust or uneven wear on both the drums and the shoes. If there is uneven wear on the shoes, you may be able to sand them to a profile that matches the drum. If the wear looks even, check your linkage for binds and wear, then lubricate all of the pivot points. If you still have the shudder, find a spot where you can lock up the wheels and then check the rubber on the surface to see if the shudder is caused by one or more wheels. Then check out the wheels that are giving you the shudder.

You could try pulling the drums again and chamfor the leading and trailing edges of the shoes,also lube where the shoes slide on the backing plates. JMO Paul in CT

Use your V-8 Club roster and contact Dave Collette in Portersville, Pa. He may be able to help you. He has experience in restoring 35-36 cars.

Thanks, Alan. Last Friday, 7/2/2021, was the fist time this truck has been driven in over 50 years so what I've experienced has happened in the past few days. The shudder is pretty loud and somewhat violent so I agree that it is probably more than just rust. I'm hoping to find a good shop to turn down the drums if there is still enough "meat" on them and tweak the shoes if that is a possibility. Any suggestions would be greatly appreciated.

Charlie, if those ten times were close together, then the shudder would not be rust. If over a period of a year or more, then that would have allowed rust to develop between drives. A drive around the block, with stops at each corner would polish off the rust.

Thanks, Alan. That would be great if it is just rust. I have experienced the shudder about ten times. I can try working the brakes a few more times to see if the situation improves. In the meantime, if anyone can recommend a good brake shop, I’d appreciate it. Charlie Demarest

As you have just now put it on the road, I’d take an educated guess that your shudder is merely surface rust in the drums, which will take care of itself in just a very few stops.

I would go for a place with experience on the early Ford brakes. Add your general location to your post and maybe someone will have a recommendation. Charlie Stephens.
