Brake--Remove malfunction2. Check the free travel of pedal.(a) Extinguish the engine, and step brake pedal repeatedly until
there is no vacuum in vacuum booster.
(b) Press down pedal with hand until feeling the resistance,
then measure the distance of this section, liking that shown
in figure.
Free travel of pedal: 1-6mm.
If it is wrong, check the clearance of brake light switch.
Clearance of brake light switch: 0.5-2.4mm
If the clearance accords with the regulation, remove the
malfunction in brake system.3. Check the distance from pedal to floor.Release parking brake drag lever
When engine is running, step down brake pedal, then mea-
sure the distance from pedal to floor, liking that shown in figure,
Force 490 N on pedal, its distance from floor should be:
over 60mm.
If it is wrong, remove the malfunction in brake system.Brake pedal assemblyAdjustment1. Check and adjust the height of brake pedal.(a) Check the height of brake pedal.
Pedal distance from floor: 136.0-146.0mm
(b) Adjust the height of brake pedal.
(1) Disassemble lower trim board of panel.
(2) Disassemble switch joint of brake light.
(3) Loosen locking nut of brake switch, and disassemble
the switch of brake light.
(4) Loosen U-shaped clasp fixing nut of pedal lever.

Brake--Vacuum booster assemblyVacuum booster assemblyInspection on automobile1. Check the vacuum booster(a) Check the gas sealed performance.
(1) Start the engine, and extinguish after one or two minutes,
then step and release brake pedal slowly several times.
Hint: if the first step is lowest, second and third step
rise gradually, and this shows the gas sealed per-
formance of booster is normal.
(2) Step down brake pedal when engine is running, then
extinguish the engine.
Hint: if the distance from pedal to floor does not
change in 30 seconds, this shows gas seal perfor-
mance of booster is normal.
(b) Working inspection.
(1) When engine is at parking state, step brake pedal sev-
eral times to check brake pedal.
The height from floor should not change.
(2) Step down brake pedal, then start the engine.
Hint: if pedal drops a little, this shows working is
normal.2. Check vacuum check valve(a) Check vacuum check valve.
(1) Remove pipe clamp, and disassemble vacuum pipe.
(2) Disassemble vacuum check valve.
(3) Blow air to check: in the direction from booster to engine,
the check valve should ventilate, but its opposite direc-
tion should not ventilate.
(4) If finding any malfunction, change vacuum check valve.Change1. Discharge brake liquidNote: do not spill the brake liquid on paint surface of automobile body, if having, wash it cleanly.2. Disassemble air filter assembly [64000033]
