Hi guys, new here.
I own a 1930 A Colonial cab, and have siezed rear hubs.
Im new to all this, and need advise on how to pull it apart, and fix it as well as replace left side backing plate, which im waiting on new one to arive.

Im on the hamb, but after searching both sites, ive come up with nothing.
Im doing this by myself, so any advise would be very helpfull.
Thanks, check my albums for pics of pickup.
Ill do a better explaination on the cab later.
Jeff.

You need a hub puller. I have gotten them off with a standard three jaw Crafstman wheel puller but you might want to invest in something a little more substantial.

The A ones come off pretty easy with the small three jaw Craftsman. The AA ones can be a real PITA.
 
Jeff, Do the drums turn and can you turn the adjusters? If
not the linings are probably rusted to the drum. Let us
know and we can go from there.

A bit of heat on the taper might help too. Also a bump with a hammer on the end of the puller when it is cinched down helps.
 
If you are going to do the whole rear end you will need a spring spreader.
(The chances are the axle hubs are worn out.)
Get a good one and EDUCATE yourself on how to use it.
There have been volumes of info written on the various model A websites on the SAFE use of them.

Bob, the drums dont turn, they're stuck pretty good.
I havent tried adjusters, but have been spraying WD40 on everything for the last two months.
Thanks.

Thanks, im hoping i dont have to do to much to sort it, the truck was running when parked up in the late 70s.
Im slowly reading all sorts of info, and had touched on the rear spring.
Im loving learning about it, its simple, but complex all at the same time.:)
 
The first thing to do is move the adjusters all the way out, which is counterclockwise. Use the correct 4 sided wrench, so you don't round the corners of the adjuster. Heat may be needed, as well as soaking them with penetrating oil.
 
Thanks Tom, ill go and see if they will move after i finish cooking our evening meal, its six pm here. lol.
 
Ok, finished eating, and went out to have a look.
Left side adjuster is munted, so itll be a vise grip job, but right side is good. Stuck, but good.
Im using an Aussie penitrating oil called Inox. I hear Gibbs is the best, but using what i have. Just gave them both another dose, so ill see how i go tomorrow.
 
those adjusters can fool you. After all those years, the threads get pretty gummed up with rust and dirt. It will seem as if they are adjusted all the way back, but if the drum will not move off the axle more than a quarter inch, odds are the adjusters need to go back more.
 
Guys, i cant thank you all enough.
Awesome advise, ive got a good puller coming, and organised a few more things today in between other jobs.
Things move slow in my little corner of the world, but when i get into something, i move pretty quick. Hope to have everthing i need to fully sort all this in the next few days.
Ill let you all know how i get on, and hope do do a thread on my "strange" cab in the next few days.
 
wd 40 stinks as a penetrant, its an electrical drier, try a 50-50 mix of acetone and auto trans oil, get two 3 or 4 pound hammers, put one one one side of the drum snout as a back up, smack the other side of the snout with the other, give it a pretty good whack, do that all the way around the snout, do the same with the brake drum, but dont hit it as hard as you do the drum snout, using a back up hammer and hitting with the other side will distort the drum and snout a small amout helping to break loose the the rust that is holding things together
 
You have two conditions to deal with. The advice offered about loosening the adjuster and breaking the shoes loose from the drums should be followed first. Once the drum is loose from the the shoes you will be able to turn the drum. At that point you can work on getting the drum off the axle which is the step that requires the puller.
 
Sometimes the drum comes off with a bang, so fix up something to control it if it does. Maybe a heavy blanket draped in front, with something more substantial behind that. You wouldn't want the drum to smash into your Aston Martin.
 
Got it done.
A few good wacks, a little heat, some more wacks and messing about with a homemade puller a friend made at trade school, and they came off.
Looks like it had good shoes a long time ago.
Unfortanatly, the adjusters are had it, but i need new backing plates anyway.
Heres a few pics of todays progress. :)
