First you need to go buy some brake fluid. A quart should do. Fill up the reservoir. A key to this is don't let it go dry. Get a friend that can follow directions in the drivers seat and you to the right rear wheel. Say brake down and friend pushes on brake with the engine off. You open the bleeder and fluid spits out. Friend holds the pedal down til you say up. You tighten the bleeder while he is still holding it down. Then he lets up. You then repeat this 15 times. Then go to the left rear wheel and do that one 15 times or until air stops coming out after the 15 times. Then go to either front wheel and do them 5 times each. After each wheel check and fill the reservoir. You should have your brakes back after that if you changed your brakes correctly. Good luck.

Only if the brake system has been opened where air could be induced.

the only reason to bleed your brakes is if you have done some work like changing brake shoes, cylinder work etc. otherwise leave it alone. If it does need it, have it done if you dont know what you are doing.

Lincoln IS. Not "Is" as you wrote. This is a sub model identification of this car. If you look at any dictionary, there is quite a bit of difference between the word BRAKES and BREAKS. I suggest you do that. What you ask about is only done by experts. Those who are not trained and certified as to auto repairs or service need to find someone that is. Tragic car crashes and more expensive repairs and even injuries have resulted from untrained people attempting to do "repair" or "service" automobiles. DO NOT ATTEMPT.

Not unless you have a reason to.

brakes??yes
