111 vs. 189 brake shoes
Posted by: junkman ()

What is the difference between a 111 and a 189 brake shoe, except for the additional metal tabs that are spot welded to the top, where they contact the anchor pin? I looked at each, and don't see any differences in the locations of the various holes that are drilled for the hardware. Can the 111 be used in place of the 189, and if so, would it be all early models, or just those that didn't have automatic brake adjusters? thanks Junk

Isn't the Concave smaller on the 111's?

I will take a pair out to check that, but I rather doubt it, since the front and rear brake drum is 1960-1963 on the rear, and 1960 - 1964 on the front.
I just checked Clarks website, and the only thing that I find is the anchor bolt is showing as 1960-1961 and 1962-1964. How much different, I don't know. Would need one of each to measure. The do say that it is thicker where it rides on the pin, however, they also say that the one number that they sell fits 1960-1964. I guess that I might have answered my own question. Still would like to hear from those that have tried the 111 shoes on a l962, 1963, or 1964 car.

Anchor pin bolt is smaller.

That's what I remember...and the shoes at "rest" never contacted the smaller pin when using 189's on a small pin backing plate

To use 189 on 60-61, you can obtain a bronze bushing at the hardware store to pick up the gap space. I found that a convenient way to use larger shoes on the 60-61 but going the other way, you have to use the smaller pin. Corvair Ranch had those in the past.

I have put 189 shoes on a 60-61 with no issues. The only difference I saw the 111 shoes have extra pieces spot welded to the pin area making it thicker there.

I stopped putting 111 shoes on years ago with no changes.

I did some further checking, and learned that if you use a chisel, you can knock off the shims on the upper part of the brake shoe, and use the 111 shoe on the later EM cars. The difference is in the anchor pin depth, not the diameter.

The pivot pin on the park brake actuator arm is taller (and thinner if i recall correctly) on the 60-61. Using 189s on the rear of a 60-61 with the stock arm it will flop around. Dont know how it will affect the function of the park brake.
