Please Help My Car Is Rolling!!!!

When I come into my driveway (Which is on an slight incline), I normally press in the clutch (While in 1st gear), and hold the brake till I shut the car off then i let out the clutch and release the brake, then I pull my ebrake. Well this time when i cam into my driveway my brake pedal went to the floor and it wasn’t stopping me, so I pulled my ebrake which was barely holding the car. Right now I have blocks of wood uder the wheels, can anyone tell me what to do? What wrong with my teg, the brakes have been very bad lately.

Possible problems are:

  1. Low (or more like NO) Brake Fluid
  2. Bad Master Cylinder
  3. Broken brake line.
