Brake System - BYD M6 Owner's Manual

Brake System

The tandem master cylinder
essentially two separate
cylinders combined into one unit,
providing two individual hydraulic
circuits. In case that one circuit fails,
the other can still function normally.
But at this time, you will get a harder
brake pedal and longer braking
distance. And the braking system
indicator comes on too.
CAUTION
Don't drive the vehicle with one
braking circuit failed. Repair the
failed braking
immediately.
Vacuum Booster
The vacuum booster uses engine
vacuum to provide power assist in
braking. If the engine stalls while
driving, you can step down the brake
pedal with normal pressure.

Don't press the brake pedal if
master
the engine stalls. The vacuum
pressure decreases with each
action of the brake pedal.
Even if the brake booster cannot
provide power assist, the brake
system can still work. But at this
time, you will get a harder brake
pedal and
distance.
Anti-lock Brake System
Anti-lock Brake System (ABS) is
designed to help prevent the wheels
system
from ceasing
avoiding braking skid. It can improve
the steering stability in hard braking
and on slippery road surface.
How to Press ABS Brake Pedal
When the ABS functions, you may
feel a slight brake pedal pulsation or
notice some noise. Just hold the
CAUTION
longer braking
rotation, therefore
brake pedal down firmly and let the
anti-lock system work for you. Don't
step down the brake pedal repeatedly
in hard braking. This may reduce the
braking performance.
On rainy days, the ABS system will
activate on slippery road surface such
as a bridge steel plate and well cover.
When you start the engine or begin to
drive away, you may hear momentary
motor or clicking noise in the engine
compartment. This is normal as the
noise indicates the ABS system is in
self-checking.
The followings may occur when ABS
is working. They don't indicate that
the ABS is malfunctioning.
You can hear the working noise of
the ABS system, and feel a
pulsation in the brake pedal and
vibration in the steering wheel and
vehicle body. You may even hear
motor noise after the vehicle stops.
