BRAKES
Brakes
GENERAL INFORMATION
WARNING: Driving through heavy
rain or water can have an adverse
effect on braking efficiency. Under such
circumstances, It is recommended that you
lightly apply the brakes intermittently, to
keep the brakes dry.
WARNING: Do not rest your foot on
the brake pedal while the vehicle is in
motion unless you are applying the brake
pedal.
Your Revero is equipped with an advanced
electro-hydraulic brake control unit that
combines the vehicle’s conventional
hydraulic brake system with its
regenerative braking system to meet the
requirements for slowing the vehicle.
The brake control module interprets the
braking request and uses regenerative
braking, conventional hydraulic braking or
a combination of both as necessary.
Unlike conventional vehicles which have a
vacuum operated brake servo to assist in
the application of the brakes, A pump
within the control unit pressurizes the
brake fluid to apply the brakes. You may
occasionally hear the pump when the
system is operating. This is normal and not
a cause for concern.
If the brake warning
light illuminates while
driving, accompanied
by the message, ”Service Brakes,” stop the
vehicle as soon as safety permits and a
have the cause investigated by your local
Karma Service Provider.
In the event of a brake problem or a loss of
vehicle power, the brake system can still be
operated to bring the vehicle to a stop, but
the brake pedal may be harder to push and
the stopping distance may be longer.
ANTI-LOCK BRAKING SYSTEM
(ABS)
WARNING: Always maintain an
appropriate stopping distance from
the vehicle in front of you. ABS cannot
overcome the physical limitations of trying
to stop the vehicle in too short a distance,
cornering at too high a speed, or the
danger of hydroplaning, i.e. where a layer
of water prevents adequate contact
between the tires and the road surface.
WARNING: Always drive with
consideration for the current road,
weather and traffic conditions.
The ABS is designed to prevent the wheels
from locking while braking, thereby
enabling steering control to be retained.
Under normal braking ABS will not be
activated. However, if the braking force
exceeds the available adhesion between
tires and road causing the wheels to lock,
then ABS will automatically come into
operation.
The ABS monitoring system checks that all
electrical components are working
correctly as soon as the vehicle is put into
Accessory mode, and also at frequent
intervals during a journey.
The ABS warning light illuminates
briefly as a bulb check when the
vehicle is put into Accessory mode. If
the light illuminates at any other time, the
system has detected a fault and the ABS
system has been shut down.
Note: The other functions of the braking
system remain fully operational and are
not affected by any loss of the ABS.
However, braking distances may increase.
