Brake size question

[70SwingerGuy]

So Im looking around for wheel bearings for my Swinger, and Im seeing in the application descriptions for 9", 10" or 11" brakes. Am I correct to assume that by 11", they means disc, for there were no 11" drum brakes(as far as I know )

If that’s how they’re listing their wheel bearings there’s no telling what the 11” ones are for. I wouldn’t assume anything other than whatever website you’re looking at has a terrible cross reference.

I went fairly loose with that description.... Summit will list a specific bearing for my car, say an outer bearing, and in the application notes it will say that it fits 10" or 11" brakes. And since to the best of my knowledge, there are no 11'' drum brakes, Im assuming that 11" must refer to front disc

Well, which front disks do you have? The original '70 KH's or the 73+ single pistons?

There are 11" drums for B/E bodies, BTW.

Good to know! and Ive got the original KH

Look in the factory parts book and get the poem part number

Then Google that

KH, A2 and A6 same as 10" drum

Exactly, A2 and A6.

Yup, A1 and A4 for the 9" brakes, and A2 and A6 for the 10" drum and KH disc '72 and older. '73-up started the A17 inner bearings.
