Brake Booster - Chery SQR7240T User Manual

Work descriptions
braking system
It is normal that the braking system makes
a noise once in a while. However, the
brake disc may suffer heavy wear and is
necessarily replaced, if metal milling noise
or zip lasts for long. In such a case, turn to
Chery chartered service
inspection & repair.
Head to Chery chartered service station for
inspection & repair, if persistent jittering
or vibration is transmitted to the steering
wheel during braking.
New brake lining can achieve its best
braking effect only after green run. In the
initial 200km, the braking effect is abated
slightly; in such a case, the braking effect
can be compensated with more efforts in
stepping on the brake pedal. This key
point also applies to new lining replaced.
Wear conditions of brake lining depends
largely on operating conditions and mode
of driving. The working conditions for
brake lining are more rigorous for urban
traffic vehicles due to frequent startup and
stoppage. Therefore, head to Chery
of the
chartered
thickness of brake lining or replace the
brake lining necessarily in consideration
of the maintenance mileage as specified in
the maintenance manual.
Shift in a lower gear appropriately in
downslope running, making full use of the
station for
braking function of engine to mitigate
loads of the braking system. At this
moment, don't keep stepping on the brake
pedal even if braking is required.
Wet brake disc degrades braking efficiency.
In water related conditions, rainstorm or
after car wash, step on the brake pedal
slightly to generate heat between brake
disc and brake lining to evaporate water
for restoration of braking effects.

Brake booster:

Brake booster is subject to
vacuum control of engine.
This device functions only
when the engine works. Thereby, don‟t
slide with loss of ignition in downslope
running.
If brake booster can't work due to that the
vehicle is drawn by a tractive force or fails
itself, step on the brake pedal with more
efforts to compensate the booster.
Each pedal should be stepped
on to the bottom and fully
return into place, keeping
flexible movement.
Therefore, the floor around the brake
pedal shouldn't be paved with foot pad or
other coverings to the best. If necessarily
paved, the foot pad shouldn't curb pedal
movement and slide.
