Hint: details could refer to operating instruction for handle tester.2. Check the function of hydraulic .(a) Start the motor relay, and check hydraulic motor should have working sound.
(b) Stop the motor relay.
(c) Step brake pedal for 15 minutes, and check brake pedal should not be stepped down.
(d) Start the motor relay, and check brake pedal should not have any pulse.
Note: Time when motor relay locates ON could not exceed 5 seconds, when it is necessary to
operate continually, interval time should be over 20 seconds.
(e) Stop the motor relay and release brake pedal.3. Check the function of right front wheel.Note: forbid making electromagnetic valve be ON in following situations.
(a) Make following operation when brake pedal is stepped down.
(b) Make electromagnetic valve SFRH and SFRR be ON at the same time, and check the brake pedal
should not be stepped down.
Note: Time when motor relay locates ON could not exceed 5 seconds, when it is necessary to
operate continually, interval time should be over 20 seconds.
(c) Make electromagnetic valve SFRH and SFRR be OFF at the same time, and check the brake pedal
should be able to be stepped down.
(d) Make electromagnetic valve SFRH and SFRR be ON at the same time, and check whether the brake
pedal could return.
Note: Time when motor relay locates ON could not exceed 5 seconds, when it is necessary to
operate continually, interval time should be over 20 seconds.
(e) Make motor relay be OFF and release brake pedal.4. Check the function of other wheels.Check the electromagnetic valves of other wheels by same procedure.

13. Check the switch of indicating light of brake liquid level.
(1) Disassemble the cover and filter screen of liquid storage tank of brake main pump.
(2) Disassemble the joint.
(3) Check the conduction between switch side joints.
Float (switch is OFF): not conduction
(4) Use siphon and other tools to absorb brake liquid in storage tank.
(5) Check the conduction between switch side joint terminals.
Sink (switch is ON): conduction
(6) Pour brake liquid into storage tank.
Inspection
1. Check the switch of indicating light of brake liquid level.
Check the conduction between switch side joint terminals.
Float ((switch is OFF): not conduction
