D - Pressure restored:
by opening the inlet valve (10-12) momentarily, the pressure of the callipers
(8-9) is increased until maximum deceleration is reached. Then, the system gives the control over the
braking back to the rider.
E -
If the wheel does not reach complete grip, the system continues operating as before until complete
grip is obtained or until the vehicle stops. An error can be detected if the duration of the pressure
reduction phase exceeds the pre-set time limit.
ABS SYSTEM DESCRIPTION
The ABS system is a device to avoid wheels locking in case of emergency braking, increasing vehicle
braking stability when compared to a traditional braking system.
Sometimes when the brake is operated, the tyre locks with a consequent loss of grip, which makes it
difficult to control the vehicle. A position sensor (3) on the tone wheel (2), forming an integral unit with
the vehicle wheel, "reads" the status of the vehicle wheel spotting any possible lock.
A control unit (1) signals this out and adjusts the pressure in the braking circuit accordingly.
NOTE
WHEN THE ABS SYSTEM STARTS WORKING, A VIBRATION IS FELT ON THE BRAKE LEVER.
THE WHEEL ANTILOCK BRAKING SYSTEM DOES NOT PREVENT FALLS WHILE ON A BEND.
AN EMERGENCY BRAKING WITH THE VEHICLE INCLINED, HANDLE BAR TURNED, ON UN-
EVEN OR SLIPPERY ROADS, OR WITH POOR GRIP CREATES LACK OF STABILITY DIFFICULT
TO HANDLE. THEREFORE, RIDE CAREFULLY AND SENSIBLY AND ALWAYS BRAKE GRADU-
ALLY. BRAKING WHILE TURNING A CORNER IS SUBJECT TO LAWS OF PHYSICS WHICH NOT
EVEN ABS CAN ELIMINATE.
When the sensors (3) detect a significant speed difference between the rear and the front wheels (for
example, when rearing up on the back wheel), the ABS system could take this as a dangerous situation.
In this case, two things may occur:
•
The ABS system intervenes by releasing pressure from the calliper until the wheel turns
again at the same speed of the other wheel. It is not possible to brake for an instant.
•
if the speed difference lasts long, the system may detect an error and deactivate the ABS
system. As a consequence, the system works like any regular braking system.
