Bleeding Brake System
CAUTION:
ICarefully monitor brake fluid level at master cylinder dur-
ing bleeding operation.
IIf master cylinder is suspected to have air inside, bleed air
from master cylinder first. Refer to ªInstallationº, ªMAS-
TER CYLINDERº, BR-16.
IFill reservoir with recommended brake fluid ªDOT 4º. Make
sure it is full at all the times while bleeding air out of sys-
tem.
IPlace a container under master cylinder to avoid spillage
of brake fluid.
IFor models with ABS, turn ignition switch to the OFF posi-
tion and disconnect ABS fuse or battery cable.
IBleed air in the following order:
Load Sensing Valve air bleeder (Models equipped with LSV)
"
Left rear brake
"
Right rear brake
"
Left front brake
"
Right front brake
1. Connect a transparent vinyl tube to air bleeder valve.
2. Fully depress brake pedal several times.
3. With brake pedal depressed, open air bleeder valve to release
air.
4. Close air bleeder valve.
5. Release brake pedal slowly.
6. Repeat steps 2 through 5 until clear brake fluid comes out of
air bleeder valve.
7. Tighten air bleeder valve
