New Rear Hub

[jwaldrich]

I've read a fair amount and I keep coming back to the statement about "matching shoes to hubs".

I purchased a new hub and discovered it will not fit over the brake shoes.

Is it common to have to mill a new hub in order to install it with good to new shoes?

Thanks in advance.

when you say hubs do you mean drums? or new drums with hubs? is this for front or rear or both? which ones are you having trouble with?

[edmondclinton]

Hub?

You mean drum.

Make sure the adjusting wedge is backed off so as not to expand the shoes. Then see if the drum will go on.

? Are you asking about brake drum or hub itself. The statement should be matching shoes to brake drum. If you had a new brake drum mounted to your hub then the drum needs to be turned to be centered to the hub. If you got the new drum/hub from Snyders, it's preturned and ready to bolt on. In eather case the shoes need to be checked for fit to the drum(s).

I'm sorry. Yes I mean rear drum.

You have the shoes arced (ground down) to match the hub. Try your local clubs and see who does it in your area. Between disc brakes the EPA and OSHA it is hard to find someone with the machines to do this. Also check with the place your purchased your shoes and see if they can do it or send them back to the place that relined them for grinding.

I "played" with that and I am thinking they are backed off about as far as they will go. I turned it counter-clockwise to back it off.

How far can you go?

it is probably hanging up on the e brake shoes

I bought a new drum with the hub swedged to it.

I had excessive axle end play and was attempting to fix that. Tore rear end completely down, replaced ring and pinion gears (broken tooth on ring gear) and replaced one axle. It bought a used axle but in very good shape sold to me by a local, well respected guy who deals in used Model A parts.

Put new bearings and double race in banjo where the drive line goes through. New drum also got new bearings etc.

One drum showed "rubbing" inside against the face (backside of the lugs). This is the drum I replaced with new. I took the brake assemblies off as a unit so no brake work was done. The brake shoes show little to no wear.

It is hanging on the brake shoes which is why I posted the original question.

after the new drum was swedged did it get trued and resurfaced?

[1930artdeco]

did you A: turn the drums to true them up and B, the shoes may need a small amount of arching to them. It depends on if you are using bonded or woven. But either way i think those two items will fix the problem.

I think what Mitch was trying to get across with an economy of words is that the E (emergency) brakes are not effected by the adjusting wedge and may be partially applied. Check to make sure they are not.

[Mitch//pa]

new drums come manufactured thicker to allow for resurfacing and truing. if they were not done they may just be to thick. thats why i asked if they were machined after swedging.

[edmondclinton]

The inside diameter of the drum is supposed to be 11 inches if memory serves me correctly.

[Kurt in NJ]

Perhaps the old drums were worn and thicker lining was used

[jwaldrich]

The new drum has NOT been turned so that is undoubtly the problem. Will see about getting that done today.

yes i would and even if it did fit over the shoes they need to be trued to the hub after swedging or most likely it will pulsate badly on braking
good luck

You must center the brake shoes to the axle housing. The drum will may not clear the shoes if they are to low or to high on the axle. You can purchase a brake centering tool from most Model A suppliers.
