If the brake paddle feels hard and high no air in brake system, what you need to check is your power brake booster, here's how to check it, make sure that the big vacum hose that goes to the brake booster has vacum with engine on (sit in back of master cylinder) then with engine off press on brake paddle three time's, should be hard, keep foot on brake paddle start engine paddle should go down a few inches if it does, take foot of of paddle turn engine off, should be able to step on brake paddle three time's before it get hard again, if none of this happen while testing bad brake booster replace.
***Seek out professional help this vehicle is not safe to operate.***
\015\012Check the vacuum line going to the brake booster.
