Clean the bleed screw on the working cylinder from dust and dirt and unscrew it about 1.5 turns. Place a hose over the head of the fitting and immerse the lower end of the hose in a clean container of hydraulic fluid.
Pour fluid into the hydraulic reservoir.
Depress the clutch pedal sharply and tighten the bleeder screw. Gradually release the clutch pedal.
Repeat these operations several times, tightening the fitting while the clutch pedal is in the front extreme position until no more bubbles come out of the hose.
