@Eugen That sounds like a bad situation with those injectors. Yea I guess your right practice does make perfect, but it sure can be aggravating!
I went over that leaky cylinder again and put it back on the truck. I thought I’d test it with out the drum so I ran a heavy strap around the brake pads and bled that side.
Guess what? Now the drivers side rear is leaking!!
Well, what to do?
I could go through them all again. I could probably, maybe, possibly finally get them to seal, but would I trust them?
And if I go too far with honing them the seals won’t fit. From my research finding the right over size seals isn’t going to happen.
Who knows how much fiddling I’d have to do before I would call it good. Not to mention it’s kinda a pain in the

to keep taking it all apart.
So I’d did some looking online and Napa offered new ones at a 20% discount with free shipping! So that’s enough of this nonsense! New cylinders it is!
They came in today, so this evening I went to the shop and got to it.

I got the passenger side all buttoned up again and the new ones mounted on the drivers side and the drum back on. I’ll have to finish up tomorrow when I’m fresh, I’m done for the night.

Hopefully, finally this will be the end of the brake part of this project.
I’ve said before that I would rather rebuild things instead of just replacing them, but in this case I think it’s the right call. I gave it a shot and failed miserably. If it was some other less essential component I’d probably keep messing with it but I don’t think the brakes are something I want to not have confidence in!
I think that will do for a Friday night truck ramble!
