what line go's where?

New wheel cylinders cost ~$6, so most people just replace them when restoring the brake system. But you can rebuild yours w/ a $1.50 kit and a cylinder hone to remove rust pits. I then blow thru all the tubing w/ air, followed by ethanol when switching to DOT 5 silicone fluid, then air and dry 2 days. New rubber hoses if they look anything but new. When you don't get flow from a bleeder, remove the bleeder because it can get clogged w/ rust gunk. You can find a rusty mess if new fluid hasn't been flushed thru for 10 years. My 1982 Chevy S-10 had a rusty, leaking rear cylinder when only 4 yrs old, so wonder what crappy fluid they installed at the factory. Why I use silicone in all my non-ABS vehicles.
