BRAKE SYSTEM BLEEDING
Procedure
This vehicle is equipped with a brake servo. It is
important that the servo is not applied during the
bleeding operation, regardless of the procedure
used.
BLEEDING WITH PRESSURE BLEEDING APPARATUS
• Fill apparatus with brake fluid and pressurize. Do
not exceed the pressure recommended by the
equipment manufacturer.
• The compressed air must be humidity-free. Before
connecting the air hose check that no water
droplets are present in the line.
• Let the apparatus stand pressurized for a while to
prevent possible foaming.
BLEEDING
Do not exceed a pressure of 1.2 to 2 bars (17 to 29
psi) to prevent foaming.
• Attach a bleed tube to each bleed screw and route
each one into a clean container.
• Fill the fluid reservoir to the brim with new fluid.
• Screw
the special cap onto the reservoirs and
connect the apparatus to the cap.
• Adjust the pressure to between 1.2 and 2 bars (17
to 29 psi), and gradually open the control valve on
the apparatus to pressurize the hydraulic circuit on
the vehicle.
• Close all the bleed screws when fluid begins to
flow from them.
• Remove the special cap.
• Check the fluid level in the reservoir and perform
a brake test.
