Warning
If the ABS is not functioning, the brake
system will continue to function as a
non-ABS equipped brake system. In
this situation, braking too hard will
cause the wheels to lock resulting in
loss of control and an accident.
Reduce speed and do not continue to
ride for longer than is necessary with
the indicator light illuminated. Contact
an authorised Triumph dealer as soon
as possible to have the fault checked
and rectified.
Inspect the level of brake fluid in both
reservoirs and change the brake fluid in
accordance with scheduled maintenance
requirements. Use only DOT 4 fluid as
recommended in the Specification
section. The brake fluid must also be
changed if it becomes, or is suspected of
having become contaminated with
moisture or any other contaminants.
Note:
• A special tool is required to bleed
the ABS braking system. Contact
your authorised Triumph dealer
when the brake fluid needs
renewing or the hydraulic system
requires maintenance.
