I've had my '60 3/4 2wd for fifty years. I think I rebuilt the wheel cylinders 30 or 40 of them ago. Sprung a leak this week winching trees in a spring clean
up while in hunkering down mode.
I thought I was lucky to find a cylinder for the left rear, 1 1/8" bore.
Turns out it was simply the wrong one in every way, even though the Centric Part number 134.66004 fits the app on every web source.
It doesn't fit in the hole in the backplate, has the bleeder at the bottom and is not compatible with the flared end on the hydraulic line. It also cost $37.
Turns out the correct one will probably a Raybestos 14521 (left side and 14522 right side). I ordered them at $8.95 each.
Anybody come across this bit of weirdness?
I am sure my truck is stock.
I think the front ones may be the same but on different sides but might not take the flare on the flex line.
No urgency, but a sort of Murphy's Law thing.
Everyone please lay low and keep well while we weather the epidemic.
