ABS OPERATION
General specifications:
The front circuit is similar to the rear circuit.
•
The ABS inlet valve (10 - 12) is normally open and it is closed only when the system inter-
venes to avoid wheel locking.
•
The outlet valve (13 - 15) is normally closed and it is opened only when the system intervenes
to avoid wheel locking.
•
When the system is in standby, the ABS processor never stops monitoring the speed of the
wheels in order to assess potential wheel slippage.
•
When in standby, the system does not intervene at all when the rider brakes; the braking
system is the same as the one without ABS.
Stages in ABS cycle (the following operations refer to the front circuit but are also applicable to
the rear one):
A - Brake activation: the rider starts braking
as he would usually do.
B - Pressure reduction:
it coincides with danger recognition (wheel slippage above threshold): the
system closes the inlet valve (10-12) and opens the outlet valve (13-15) temporarily.
At this stage the rider cannot increase the pressure on the callipers (8-9) and the system reduces the
pressure on the callipers partially. The excess fluid temporarily fills the front reservoir (18-19) until the
ABS pump (17) self-activates and delivers the fluid back to the brake pump (2-5).
C - Pressure maintained:
the pressure in the callipers (8-9) remains low until total recovery of speed /
wheel grip.
The system restores the fluid taken from the calliper (8-9) in the section of the system between the
brake pump (2-5) and the ABS inlet valve (10-12).
