I completely removed the self adjusters on my 87 F250 4x4.... When the brake peddle starts to get low, I know it's time to adjust the rear brakes... With a floor jack and a brake spoon, takes all of 10 minutes and I'm in control.. instead of forgetting about it, relying on the self adjusters that never work anyway.
It's a system that has worked fine for me for quite a while now. Your mileage may vary.
Bleeding brakes: I use a cheap electric fuel pump hooked to the longest line wheel first, to suck the old fluid out, then the next shorter line , etc.. close all the bleed screws as you move to the next wheel..
Then: reverse the connection lines [use cheap poly lines from your hardware store.. one use, discard] start at the longest line, drop the pump pickup line in a clean bottle of brake fluid and pump fluid from the bottom UP to the master reservoir. When you get about 1/4 inch of fluid and no air, close the bleed screw and move to the next longest line, repeat for each wheel. Keep a watch on your master reservoir and you can of brake fluid, don't suck and pump air [of course] and don't over fill the master.
What you will do is push the air in the lines UP which is what air wants to do. When you are done, you will have lines and master that have no air in system, you don't need two people, and you have brakes first time, every time.
I use a cheapy fuel pump and a 12v battery out of a house alarm system [got it for free] so it's all easy to move from wheel to wheel..
Hope this helps... This system will also work for bleeding clutch slave / master systems.. Really well.. Pain free system.. been using it for about 10 years on all kinds of vehicles.
edit: Forgot to mention. When you are pumping fluid from the wheel cylinder back up to the master, put the cap on the master loosely. If you don't it will squirt brake juice where you don't want it.. This is particularly important if you are bleeding the clutch from the bottom up.. you will spray brake fluid [which isn't good for paint]. Just set the cap in place, no worries then.
