My pedal is going all the way to the floor where then i will get a little bit of braking. I dont think its a leak in the lines because its not building up any pressure even when pumped and i dont see much loss of fluid. Im assuming its not the booster as wouldnt that give a hard pedal but not much brake. Could it be the abs?

 

Sounds like the ol culprit of a bad master cylinder.

 

Ok also the red brake light is on on the dash

 

You sure you don't have a leak? You wouldn't get any pressure even pumping up the pedal if there is a leak in the line and the light comes on when the fluid gets low.

 

like i said though it's still full on fluid

 

Have you tried bleeding your brakes?

 

Oh thought you said you don't see much loss of fluid. The seals could be gone inside the master cylinder causing fluid to pass by not creating enough pressure.

try this first, primary piston is closet to the booster.

5. If the brake pedal apply did not feel spongy, but the brake pedal travel was excessive, perform the following steps:

 

is your fluid full in both the front and rear of the resevoir? when that happened to mine the rear caliper seals blew and drained the rear side of the resevoir to empty.

 

The fluid is full in the master cylinder and there is no front or rear also how would you get air in the lines suddenly

 

vehicle year/make/model?
