Brake wheel cylinder question.

I've disassembled my brake system and it appears all four wheel cylinders are all identical (I'm thinking for the left side). Can someone let me know does the larger bore of the wheel cylinder actuate the front or rear shoe?

Thanks.

Hello Ilsinc and welcome!
I recall the larger bore actuates the rear shoe, and there are left and right cylinders.
Glad to have you with us!

I recently rebuilt the brakes on my truck using OEM/NOS parts, and I believe that Gary is correct. I recall that the TM was specific and a lot of help.

I've seen them with "L" & "R" cast into them.
