If a hydraulic line is disconnected at the master cylinder, start at the brake caliper or wheel cylinder farthest from the brake master cylinder, and move to the next farthest brake caliper or wheel cylinder until all cylinders four cylinders have been bled. If the disconnection point is anywhere except the master cylinder, start at the point closest to the disconnection, and move to the next closest brake caliper or wheel cylinder until all four have been bled.
  1. On level ground, jack up the vehicle and support it evenly on safety stands.
  2. Remove the bleeder cap and attach a vinyl tube to the bleeder screw.
  3. Place the other end of the vinyl tube in a clear, fluid-filled container.
  4. The first person depresses the brake pedal a few times, and then holds it in the depressed position.
