I believe you have Huck brakes on a 53 3/4 ton. The "sprout" you mentioned is caused 2 things that we already know about. Either you have air in both systems or they are not adjusted Correctly. Adjusting them till you get a "slight drag" doesn't get it. Sometimes the shoes are not centered & you get a drag before they are adjusted up enough. Adjust each adjustment till you get a heavy drag. Then back it off about 4 notches. Yes it may drag somewhat but thats OK. If it has Huck brakes you have 2 adjustments on each wheel.

They say money can't buy happiness. It can buy old Chevy trucks though. Same thing.
