Chrysler Repair: brake bleeding on 96 Chrylser T&C, brake warning light, vacuum line

Question
Vehicle sat for a couple of years.  Upon using it there is no brake pedal.  I have bleed this vehicle in the pass with no problems. Now I cannot evacuate the air from any of the brake lines (no pedal, I even bleed the MC.  Finally I replaced it (bleed it also) .. very discouraged.  Have also gravity bled with no success.  Any thoughts.

Answer
Hi Greg,
If you don't get the brake warning light coming "on", the two possibilities are the booster runout point is mistaken for the bottom of pedal motion... so open a bleed fitting and see if it goes any further to the floor. Then check booster vacuum hose for crack or leak at either end, then test again; and then remove lines (and plug their ports) for the cruise control and heater/A.C. units in that big vacuum line if those are present, and retest. Measure the vacuum in the line at one of the ports, then clamp off the main hose and see if the booster unit holds the vacuum (no more than 3 in. Hg drop in 15 seconds).
If the red and the amber ABS light are "on" then the ABS system needs to be checked out (a longer desrciption that would best be xerox copied and mailed to you by US mail). Also if the red warning light comes "on" only when you actuate the pedal, try to apply the brake Very Slowly and if you get some resistance keep applying pressure and note the degree of pressure that you are applying when the light comes "on". Then write back with the results.
All the above is from a couple of pages from the shop manual for '93 vans that I have. I could copy and snail mail these to you.
Do you have any sings of fluid loss? Of does the system seem to be tight? Do you have ABS?
