rear breaks '67 3/4 ton... HELP - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Arg!!!!!!!!
I need some of your expert advice. I know I saw the answer here, but now I can't find it!

let me start with the begining. After my truck sat for the Pennsylvania winter, I noticed while I had it out today that the rear breaks want to lock up too fast. Just stopping from about 25 MPH, so it's not like I'm standing on the pedal. I pulled the driver side drum, and although it was dusty, the shoes aren't bad, (only about 600 miles, and they worked fine last summer!
This leads to question #2:
I can't remember how tight to make the 2 "ring" nuts, the ones that hold the drum on to the rear end, and also, hot tight do I torque the 8 bolts that hold the axel to the drum?
it's a '67 3/4.
Sorry about the long post!
Dave

I suspect that your brakes are fine, they likely just need some use to get back to their old selves. I hope someone can better answer your torque questions.

thanks, jku....
The service manual doesn't even mention this set up, but I knew it at one time.

I guess memory IS the 2nd. thing to go!
(Can't remember the 1st.!)

And thanks John!
I did find the specs in the service manual after my first post.
Lesson learned, never tear into your rear end AFTER a hard day at work!
