Got all the rear wheels off and trying to get the brake drums off. I have the T-150 rear axel-2 speed. My manuals show removing the 3 countersunk small screws and the drum should slide off the lug bolts. Got the screws out but drum won,t budge. Sort of afraid to use heat. I have sprayed so much penetrant and may get the brakes on fire. Thanks for any advice.

Do this on the outer flat areas, not on the edges because you may break the drum.
Also, back off the brake shoes as they may have worn a groove in the drum. | | | | | Joined: Jan 2013 Posts: 603 Shop Shark | | Shop Shark Joined: Jan 2013 Posts: 603 | I tried to back off the adjusting wheels, but they were frozen up. Finally I just removed the axel and complete hub-drum assembly. Slid right off that way.
Guess now I can use heat to separate them for easier installion.
One strange thing, every thing looked ok except for a leaking seal,and all 4 shoe return springs were broken and laying in bottom of the drum. Don't understand why all 4 were broken, they were shiny and not rusty looking.

So to separate the drum from the hub you may have to knock out the lug bolts to do so.
The screws held everything together while the lug bolts were put into place.
A lot of the newer hub/drum assemblies can be separated easily, but most of the older ones have to have the lug bolts removed to separate them.
