Manual Bleeding

Print


NOTE
Proper manual bleeding of the hydraulic brake system will require the aid of a helper.

The following wheel sequence should be used to be sure all of the air is removed from the system:



Left rear wheel
 
Right front wheel
 
Right rear wheel
 
Left front wheel
 

  1. Attach a clear plastic hose to the bleeder screw located at the right rear wheel, then place the hose into a clean jar that has enough fresh brake fluid to submerge the end of the hose.

  3. Have an assistant pump the brake pedal 3-4 times, and hold it down before the bleeder screw is opened.
  4.  
  5. Open the bleeder screw at least one full turn. When the bleeder screw opens, the brake pedal will drop.
  6.  
  7. Close the bleeder screw. Release the brake pedal only AFTER the bleeder screw is closed.
  8.  
  9. Repeat the procedure 4 or 5 times at each bleeder screw. Then check the pedal for travel. If the pedal travel is excessive, or has not been improved, enough fluid has not passed through the system to expel all of the trapped air. Make sure to watch the fluid level in the master cylinder reservoir. It must stay at the proper level so air will not re-enter the brake system.

  11. Test drive the vehicle to be sure the brakes are operating correctly and that the pedal is solid.
