    Ok, ive tried real hard to get the drums off. pulling, hitting them with a hammer, disconnecting brake lines, parking brake, tried to stick a screw driver into the little hole in the back that my service manual says is to adjust the star wheel. i cant get them off. Any suggestions? Im thinking i should just go to midas, get some lifetime brakes for it and let them do the work.

    Ok, on the adjuster...It will turn one way by itself, but you will have to depress the stop clicker gadget and turn it the opposite way. this will loosen the brakes..

    also, if the above doesn't work, and they have been on forever, you may have to heat the centre of the brake drum, around where the axle flange protrudes, with an oxy/acetylene torch...this usually gets results, but make sure you try backing off the adjuster all the way because your shoes may be catching on the lip of the brake drum....if the adjuster is siezed, then your basically going to have to use force, in this case it's easier to grind off the heads of the shoe retainer pins (they will look like nail heads on the back side of your backing plate, one at 9 oclock and one at 3 oclock, use a die grinder, but be carefull not to grind away the backing plate....when you buy new brake hardware it will come with new pins....then pry off the drum...or if you are keeping the truck forever, and don't feel up to wrestling with the brakes...as you said...head to midas....just my 2 cents...ED

    Get some PB Blaster and soak the area were the axle snub protrudes through the drum. Let it sit and try prying from the rear with a pry bar. If that doesn't work get a friend to pry with the pry bar and you hit the axle snub with a hammer at the same time.

    Just checking the basics. Sometimes there is a star nut on one of the studs holding the drum to the axle. Just use a screwdriver to back this off. Also if you rotate the drum, do you hear the brakes dragging? If so, try backing off the brake adjusting nut star wheel behind the backing plate some more.

    Next step... get a bigger hammer! I have had trucks where I had to get under with a full size sledge and beat the cr*p out of it. Have someone on the outside slowly turning it so you smack it evenly around. Worked for me...

    Emmet's idea worked for me when I had some PIA drums to get off.

    There's a little slack in the brakes, so if it's the brakes holding them on then when you smack the back of the drum it will move out and then back in. If it's just rusted on there it won't move at all. Of course, this has been my experiance.

    It's been lovely, but I have to scream now.
