Brake System Bleeding
Bleed
The following procedure covers bleeding the complete system,
but where only the primary or secondary circuit has been
disturbed in isolation it should only be necessary to bleed
that circuit. Partial bleeding of the hydraulic system is only
permissible if a brake pipe or hose has been disconnected with
only minor loss of fluid.
Warning: Do not allow brake fluid to come into contact
with eyes or skin.
Caution: Never reuse fluid that has been bled from the
brake system.
1. Top-up fluid level in brake reservoir to ‘MAX' mark.
Reservoir–Brake Reservoir–Brake Reservoir–Brake Fluid–Check Fluid–Check Fluid–Check // / Top Top Top Up Up Up .. .
Caution: Ensure the fluid in the reservoir is maintained
between the minimum and maximum levels throughout
the bleed procedure using new brake fluid.
2. Raise the vehicle on a lift.
3. At rear RH brake caliper (LHD models), remove
bleed screw dust cap and attach tube to bleed screw.
Submerge free end of tube in clear container containing
new brake fluid
4. Apply pressure to brake pedal several times, then apply
steady pressure.
5. Loosen bleed screw to release brake fluid and air.
Allow pedal to return unassisted.
6. Repeat procedure until a flow of clean airfree fluid is
purged into the container then, while holding pedal
at end of downward stroke, tighten bleed screw
to 7–9Nm .
7. Remove tube from bleed screw and fit bleed screw
dust cap.
8. Repeat bleed procedure at remaining three brake
calipers in the following sequence: rear LH; front RH;
front LH.
a. LHD models: Rear LH; front RH; front LH.
Warning: Braking operation may be seriously impaired if
the incorrect bleed sequence is used.
9. Lower the vehicle.
10. Top-up fluid level in brake reservoir to‘MAX' mark.
