BLEEDING INSTRUCTIONS

When performing the bleeding process, both front wheels must be completely off theground. Under loaded conditions (wheels on the ground), the PS fluid is injected into thecylinder under extreme high pressure. If any air is present, this will cause a foaming actionwith the fluid. It will take several hours, even overnight, to bleed out the air in the system ifthis foaming has occurred.

Jack up front wheels and place car on stands. Do not use ramps. Wheels must be free toturn.

DO NOT START ENGINE
