Other side done. Sweet jesus I am lucky I am not dead.

If you can’t tell, that is a puddle of brake fluid on the... outside of the wheel cylinder. I don’t think it’s supposed to be like that.

given how I was compressing everything to get it apart, I am pretty sure that is what a leaky line is supposed to look like. No wonder this thing stopped like shit.

Modification I had to do to the new cylinder to get it to fit. From an AC delco part on a GM car. wowie.

Also I think the jackass who did these brakes last put the bottom spring on wrong. I copied it and it interferes with the auto adjuster. which means I probably need to take this side apart again at some point.
To do today: replace rear lines, bench bleed master cylinder, hook everything back up. Gather parts for trip to machine shop tomorrow.
