Practical Blacksmithing??? | "Traditional" Blacksmithing | Forum

Not sure if this is truly "traditional", but the idea of forging a part to fix a machine may be considered traditional...
2nd use of smithing to fix my truck or, more specifically, my rear brakes. (First was hinge for tailgate.) This time, wheel cylinder on rear drum failed/broke and lost one of the two actuator pistons(?), and apparently these don't fail or break and they don't come in a wheel kit or brake kit. The local parts store said they may be able to get something on Monday, so instead of waiting, I thought, I can make one of those in a couple of hours... and I was right.
First 2 pics are original with header plate I made. Second two are original and new one after 2 hours of forging/filing. Final pair are specs on each.
