Caution / Notice / Hint

NOTE:
  • When installing, coat the parts indicated by arrows with lithium soap base glycol grease (Refer to COMPONENTS [08/2015 - ] ).
  • As high pressure is applied to the brake actuator tube No. 1, never deform it.
  • Do not turn the ignition switch ON until the procedures are completed.
  • Before starting the work, make sure that the ignition switch is off and depress the brake pedal more than 20 times.

HINT: 

When pressure in the power supply system is released, the reaction force decreases and the stroke becomes longer.
