REAR ENDS DRAGGIN

[mdenler]

my back brakes on my 1994 1 ton are dragging when i pull heavy loads causing my back wheels to smoke. they let of after i stop for awhile could this be a problem with my anti-lock braking system ?

try backing the adjuster of a little. also check that the shoes are installed properly.

i back the adjusters off and it's okay for awhile then they tighten back up again. i'm going to put a new set off shoes on tomarrow

i replaced the shoes, the wheel cylinders, springs and brake fluid everything inside the drums were fried to a crisp. the only thing i didn't replace were the self adjusters. they locked up again while i was pulling a load up a steep hill. i burned up a tire towing it up the hill with the rear brakes locked up. i don't know what to do with it. i've never had a truck that would lock up the brakes by itself.

How much weight are you pulling?

[mdenler]

today 5 tons , sometimes as much as 12 tons.

Does the truck squat on the rear a lot?

[mdenler]

sits nice and level although an extra leaf in both springs would't hurt. i pulled the same loads with my 85 6.9 3/4 ton dually for two years with no trouble i'd be using it now but it needs a throw out bearing on the clutch. i just bought the 95 350 7.3 . thats giving me the brake trouble.

maybe the ABS isn't working at all. I'll have to see what I can dig up.

I am having the same sort of problem with the 96'...except I feel it in my brake pedal. the pedal doesn't return all the way. Seems worse in the cold....I'm thinking brake booster??? Any ideas??
