I went to Napa's online catalog page for brake parts and found the front cylinders are quite a bit different from the rears. The fronts show to be 1-1/8" ID but the rears are 1" ID. I realize that this wouldn't affect the hone purchase, but I just wanted to make sure that this info is accurate: the fronts and rears really are different?

Kits are $4 each. At $8 for a brand new rear cylinder, I won't bother to rebuild them. But the front cylinders are going for $38 each- enough to justify rebuilding them.

I guess this shows how clueless I am about brake cylinder sizes. I thought Chevy would have used the same one on all four corners for standardizing.
