Check your brake fluid level in the master cylinder... you may have a leak some where
it needs to be reset by computer Turn off power. Press accel pedal to floor. Turn keys two notches. While pressing the accel press brake three times. Depress accel and turn off keys.
you either need a new brake master cylinder or your brakes need to be bled
Have your brake system checked immediately! (by a proffesional)
Try bleeding your brakes. If there is air in the system it can give a spongy feeling to your brake pedal and require you to pump your brakes and/or put your brake pedal to the floor.
Check your brake fluid. Next maybe your brake lines need to be bled. OR you just might need new brakes.
You need to bleed the brakes.
Air in the brake system- Brake system needs to be bleed and fluid needs to be added while you are doing that.
If you are losing fluid and the pedal is low, you have a brake fluid leak.
Probable causes: Low or no fluid in reservoir; Worn brake pads/shoes; Air in brake lines; Leaking brake line.
The best way to tell when you need brakes is by squeaking, when the brakes are rubbing against the metal, when your brake pedal goes all the way to the floor and when you are running out of break fluid.
try and bleed brakes , if that wont work you need a master cylander
