remove the slave, leave the master and line bolted in the truck.
Bleed the slave
at a bench, point the fluid inlet of the slave up, push down until the rod is all the way in (be careful, she spits)
have a friend start the fill the slave with fluid as you SLOWLY let the spring decompress the piston
now that its bled, get under the truck w/o spilling anything out of the slave
Bleed the line
have your friend pull the cap off the master, and let the line start the gravity bleed (may have to depress the pedal to get it started) as he keeps the res full.
once you get good clean fluid out the line, use the fluid thats coming out to make sure the slave is still full, and put the line in, put roll pin back in.
Master
the master is self bleeding, reinstall the slave, as you compress the piston the fluid will pump threw the master and into the res, make sure you compress it slowly to avoid making a mess.
Done
top off the res, put the cap on, and pump the pedal a few times, you should be good to go.
