Brake question - 1963 C20
 

I noticed Rockauto lists different sizes for brake drums, did these years come with different sized brakes? Like 11 x 2 or 11-1/16 x 2.75.

Are the wheel cylinders all basically the same?

I pulled the brakes and it looks like the shoes are 11-1/16 x 2.75.
Single wheel cylinder. Still gotta get the front ones off.

I would assume 1/2 ton vs. 3/4 ton initially but maybe they had a standard duty & heavy-duty option for C20's?

Yeah, 11"x2" is the half ton size. I'm not sure why Rockauto lists them under the C20 section, but I noticed this when I bought shoes for my '66 C20, as well.

For the record, mine are the larger 2.75" wide version, and were the same size on all 4 wheels.
