Question about Cars & Trucks
I have a 1994 Chevy S10 pickup with 2 wheel drive. I have a brake pedal problem. When the engine is not running the brake pedal is high & very firm but once the engine is started the pedal goes almost to the floor. I breed all the air out of the lines but don't know what to do next. What do you suggest. Thanks Dave T.
The booster may be bad, or the vacuum line to it (or elsewhere) has failed. Do a complete vacuum hose check, they are almost twenty years old, time for new ones. A vacuum gauge is a very handy tool to have, comes with cool tips on how to diagnose engines with it.

Did you put fresh fluid in the master cylinder? I really think you still have air in the lines. To bleed manually, start with the bleeder the greatest distance from the master cylinder, car running, helper pushing down about half way on brake pedal and releasing 3 times, on 3rd time, holding pedal down to half way depressed point while you open the bleeder valve. Repeat until you are sure all air has been flushed out. Check master cyl reservoir level often, because if it gets low and you **** air into the system, you have to start all over again. Go to wheel next greatest distance from master cyl, repeat above, working your way to wheel closest to master cyl last.
