I'm trying to remove the rear brake drums off my 12 bolt
and can't seem to get them off.

Am i missing some thing special trick or just not pulling hard enough?

Thanks

you may have to back off the shoes , but I find probably 50% of the time, smacking it with a 2 1/2 pound hammer breaks it free. They bind up on the hub generally. Just smack it where the cooling fins would be if it was that kind of drum.

uhhh
no cooling fins

I wouldn't pry on that backing plate, all that does is ask for trouble.

You just want to pry hard enough to put some pressure on drum-not enough to bend backing plate.Done this many times while saying my Sunday School lesson backwards.

is non existent on the other side

Your brake shoes are not holding the drums then. They are rusted to the axle hub. Just keep soaking in rust cutter and do as I suggested. You have two differants drums then. Check at the bottom of backing plate on the back side to see if there is an adjusting hole there.

I just did my rear brakes yesterday and I had the same problem as you with my right rear. Like Longhorn man said your drum is siezed to the hub. What I did was soak the hub in PB lube and then lightly hammer a srew driver in between the drum and backing plate. When you have a little gap give the drum a good blow with a hammer near the hub. Mine popped right off.

we do this many times a day at work, we NEVER pry on the backing plate, you get written up for shoving anything in there. We just smack it good a few times where I indicated.

mvfd70 · 08-17-2007, 05:36 PM

I agree about not prying on the backing plate. A LITTLE (very LITTLE) pressure won't hurt but why chance it. Just keep smacking hit with a hammer on the hub and around the perimieter where LH Man circled. If it don't work still get a BFH out (BFH = Bigger F***ing Hammer). Worst case you'll crack the hub since it's cast, but it will be off. It needs replaced anyway, right?

I just went through this and I offer the word patience. I had a very hard time with that but in the end it came off. Good Luck
