Brakes, AGAIN

[CaperKen]

I've read and viewed a huge amount of material about how to get a new toggle-type brake band onto the brake drum.

It seems that the key lies in bending the metal tab inward just at the point where the lining ends on the longer metal tab.

However, after working on bending that tab one way and then the other for two days, when I get the band onto the drum, the shaft will not turn. And, getting the band to fit on the drum is a terrific effort.

Has anyone put the brake drum on a lathe and ground off maybe a 1/16 inch to 1/8 inch to get the band to fit?

Thanks for any help.

This is probably a stupid question, but are you sure the band is being installed correctly? BTDT

I wouldn't take material off the drum. If the band is too tight, you may need to open it up a bit so the relaxed band is not trying to grab the drum.

Well you also know the drum is right it's probably been on there since new. So that leaves the bands- where were they sourced? Is the friction material the same thickness as the original equipment? The way things go these days they could be metric since nothing is made here anymore- the thought being what's 1mm you could adjust that out.....

Hi,
Possible things that could be causing that are the brake lining may be too thick, or the brake band is slightly too small a diameter, if you replaced the band.
Or the parts are not assembled right.

I have put bands with new lining on the drums, they were snug, but went on, and were not overly tight.

Below are pics from TM Tractor of a new brake band with lining, you can look at the pics, it shows the lining thickness they have.

Below is their listing for a new brake band with lining.

Below is a pic from TM Tractor of the newer style brake, the band and linkage only fits one way.
Look closely at how the linkage is assembled.
The pic is the right side.

The 2nd pic shows putting the final drive on the Cub.
Be sure to have both ends of the brake pin in the holes before tightening the 6 bolts that hold the final drive on the Cub. It can break the castings to tighten the bolts with 1 or both ends of the pin not in the holes.

Thanks, everyone.

1. Is the lining as thick as the original? I don't know since the original is worn down. But, if it's too thick, that can be the problem. But, what's the solution?

2. I've bent the band and the tab multiple times and no satisfaction. I've watched the YouTube videos by "Surviving Maine on a 20 acre farm" but the band is just a bit too tight.

3. I bought the brakes from Steiner about 3 years ago -- just got to it now. I've just ordered another pair from TM hoping that they will fit better.

4. I'm using new drums.

5. The pins look the same as all photos I've seen. TM Tractor does nice pics.

I'll go back at it and try bending different ways until I get it to fit and not bind the shaft.

Here's a "how to", but I think you may already be doing this. viewtopic.php?f=142&t=14715
