Rear brakes / axle / ??

I have ran a search on this forum and could not find any info. I am sure it is here somewhere it just seems like I am not entering the correct keywords...

I have a 30 "a" with hydro brakes that I am rebuilding the whole system. I have everything on except the left rear drum. When I put it on at first everything is good. When I torque the axle nut, the drum/axle locks up, I am guessing against the backing plate. I did notice the rear spring is up against the wheel cyl lower bolt. There is a wear spot on top of the backing plate where the drum hits it. There is also a shim between the axle and hub but the axle and the shim seem pretty beat up.

How can I move the drum out?

Can I trim off the drum lip?

Thanks
 
Hi Two,

Without seeing your drum, your backing plate, beat up axle shim & axle, one easy & not time consuming thing to try is first to forget about your existing drum for a moment.

Next, just as easy, obtain another drum just in case the tapered part of your drum that fits on the axle has just about had it.

Just one of hundreds of suggestions to follow.

Anyone in the Kent/Auburn Washington area have a spare drum?
 
Your axle or hub taper may be worn.The 40-48 ford brakes need to be spaced out slightly to prevent the inner edge of drum from hitting backing plate You could have a bit of the lip cut off on a lathe or carefully ground off with a hand held grinder.If tapers are good, then 2 axle shims per side will usually work without grinding the lip on drum.If the rear spring is hitting the wheel cyl bolt,then it may be pushing the B plate towards the drum causing it to rub at the top.Personally,I feel that the stock brakes work very well when properly rebuilt & set up.They can also sit for years and they will still work.Try that with hyd brakes ,especially in a humid climate!
 
He's already got the hyd brakes installed so telling mech are better or as good is naught.
Grind off from the back of the drum and/or add shims as was stated above.
If I had the money I would convert to hyd in a heart beat. JMO
