ANTI-LOCK BRAKE SYSTEM
If the brakes are applied under these condition, the
ABS has to reduce the braking force to ensure and
maintain the directional stability when the wheels
regains its contact with the road surface. At this
instant the ABS must reduce the traction, so that the
wheels will continue to rotate under all imaginable
circumstances, because this is the precondition for
ensuring directional stability. As soon as the actual
circumstances arises, the system reacts instantly and
adjusts braking force accordingly to achieve optimum
braking.

HECU
Why does brake pedal / lever pulsate during brake
application?
Vehicles fitted with ABS uses the conventional brake
system during normal operation. But during hard
stop the brake pedal / lever feels different, i.e., a
rapid pulsation in the brake pedal / lever; This is
absolutely normal.
It is not necessary to have this pulsation feel every
time the brake is applied. Pulsations are felt only
during wheel locking tendency, occurs due to the
modulation of pressure in the brake circuit by HECU.
Pulsation means that the vehicle is in limit. This
pulsation feel also depends on the road condition.
Rear wheel lift
Under very severe and sudden deceleration,
however, under certain circumstances it is possible
that the ABS unit fitted in your vehicle will be unable to
prevent the rear wheel from lifting clear of the ground
and flip over.
Severe braking can cause the rear wheel to lift off the
ground. When you brake, bear in mind that ABS
control cannot always be relied on to prevent the rear
wheel from lifting clear of the ground.
