Just a suggestion.....on the "HELP" aisle at your favorite local parts supplier (Advanced/AutoZone, etc) you'll find a little pack of SPEED BLEEDERS (2/pkg/$9.00)....you replace the stock bleeder screws, fill up the master cylinder, crack the furthest wheel cylinder, attach a hose to a catch can and sit in the drivers seat and gently pump 6-10 pumps and the SPEED BLEEDERS keep air from sucking back into the system. Close the furthest, refill the M/C, go to the next and repeat the operation on all the others.
The only downside is that you've gotta watch the level in the master cylinder. It's soooooo easy
you might run it dry.
Carry one of your old bleeder screws with you as there are 3 different thread configurations. Once you use the SPEED BLEEDERS you'll shelf your ole vacuum pump, pressure bleeder and your "bleeding partner" can sip on a brew while you bleed ALL the air or REPLACE the nasty fluid in your entire system with a minimum of effort.
It's the best $20.00 you'll spend on your truck!!! I know this because...
