I want to thank all of you for the good ideas and help.
I have some homework to do:
Pressure test
Test brakes in reverse
Check condition of backing plates (pads)
Swap backing plates and shoes to another wheel
Check spring mounts/u-bolts
Verifiy that e-brake is properly adjusted
I'll go out and try these over the next few weeks (it's busy around here) and report back.
Thank again!
On the pressure test, it would be nice if you could do both rear wheels at the same time. They sell adapters that replace the bleeder screws. Have a helper depress the pedal as you record the readings on both sides. I would encourage doing so while appling and holding various pressures.
When swapping backing plates shoes etc, doe the drums as well.
On the e-brake MAKE SURE
BOTH cables move freely
One last thought, check the run out on the axle flanges to make sure they not bent.
Good luck and keep us posted
