  1. Fill the master cylinder with fresh brake fluid. Check the level often during this procedure. Raise and safely support the vehicle.
  2.  
  3. Starting with the wheel furthest from the master cylinder, remove the protective cap from the bleeder and place where it will not be lost. Clean the bleeder screw.
  4.  
  5. Start the engine and run at idle.
    CAUTION
    When bleeding the brakes, keep face away from the brake area. Spewing fluid may cause physical and/or visual damage. Do not allow brake fluid to spill on the car's finish; it will remove the paint.

  6.  
  7. If the system is empty, the most efficient way to get fluid down to the wheel is to loosen the bleeder about 1/2-3/4 turn, place a finger firmly over the bleeder and have a helper pump the brakes slowly until fluid comes out the bleeder. Once fluid is at the bleeder, close it before the pedal is released inside the vehicle.
    NOTE
    If the pedal is pumped rapidly, the fluid will churn and create small air bubbles, which are almost impossible to remove from the system. These air bubbles will accumulate and a spongy pedal will result.

  8.  
  9. Once fluid has been pumped to the caliper, open the bleed screw again, have the helper press the brake pedal to the floor, lock the bleeder and have the helper slowly release the pedal. Wait 15 seconds and repeat the procedure (including the 15 second wait) until no more air comes out of the bleeder upon application of the brake pedal. Remember to close the bleeder before the pedal is released inside the vehicle each time the bleeder is opened. If not, air will be introduced into the system.
  10.  
  11. If a helper is not available, connect a small hose to the bleeder, place the end in a container of brake fluid and proceed to pump the pedal from inside the vehicle until no more air comes out the bleeder. The hose will prevent air from entering the system.
  12.  
  13. Repeat the procedure on the remaining calipers in the following order:
    1. Left front.
    2.  
    3. Left rear.
    4.  
    5. Right front.
    6.  

  14.  
  15. Hydraulic brake systems must be totally flushed if the fluid becomes contaminated with water, dirt or other corrosive chemicals. To flush, bleed the entire system until all fluid has been replaced with the correct type of new fluid.
  16.  
  17. Install the bleeder cap on the bleeder to keep dirt out. Always road test the vehicle after brake work of any kind is done.
