⋅⋅⋅⋅⋅m
(b) Use centimeter to measure the terminal run-out of brake
disk on the position with 10mm apart from the exterior edge
of brake disk.
Maximal run-out quantity: 0.15mm
(c) If terminal run-out of brake disk exceeds or equals to maxi-
mal value, firstly, check the axial clearance of bearing, then
check the terminal run-out of shaft hub, if they are both
normal, adjust the terminal run-out of brake disk to eligible
value or use turning motor to turn terminal surface of brake
disk.
17. Lock exhaust bolt of rear brake branch pump
temporarily.
Lock exhaust bolt to rear brake branch pump temporarily.

24. Assemble rear brake block.
Note: when changing brake block, the inside of muffle gasket should be changed together.
(a) When assembling muffle gasket on every brake block, it is necessary to spread brake lubricating
grease on the inside of muffle gasket.
(b) When assembling inner brake block, abrasion indicator should face upside.
Note: do not attach any oil dirt or lubricating grease on the surface of brake block and brake
disk.
(c) Assemble two guide pins of brake block.
(d) Assemble fixing clamp of anti-abrasion spring.
25. Add brake liquid in storage tank.

Inspection on automobile
1. Connect handle tester
(a) Connect handle tester to DLC3.
(b) Start the engine and make it run at idling speed.
(c) Handle tester should choose “Active test” module.
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.
