Troubleshooting
INTERVENTION
Check the wear of the brake pads (MIN. 1.5
mm).
Ensure that the brake discs are not worn,
scored or distorted.
Check the brake fluid level in the pumps and
if necessary renew the brake fluid.
Check for air in the circuits and bleed it as
necessary.
Ensure that the front brake caliper moves
along the disc axis.
Check the tightening of the brake disc screws.
Using a comparator and with the wheel fitted
on the vehicle, measure the axial runout of
the brake disc.
Flexible connections, piston or brake pump
gaskets faulty. Replace
Check caliper, renew any damaged part.
Check the tightening of the brake disc screws.
Using a comparator, measure the axial shift
of the disc with the wheel fitted on the vehicle.
Clean thoroughly and blow with compressed
air.
Replace the gaskets.
Check the tightening of the upper and lower
ring nuts. If steering rotation is still uneven,
check the bearing ball rolling races. Replace
if the races appear to be embedded, or if the
balls are flattened.
Ditto
If the front suspension is noisy, check the
operation of the front shock absorber, the
condition of the ball bearings and of the
related locknuts, the rubber stops and the
sliding bushes.
Also check the tightening torques of the
wheel hub, the brake caliper, the brake disc
and the shock absorber on the hub and
steering tube connections.
Replace the shock absorber.
Check the wear of the steering caps and
adjusters.
With the ignition switch in the ON position,
jumper contacts 1 (Blue-Black) and 5 (Red-
Blue) on the electronic control unit connec-
tor. If the turn indicators do not light up and
stay lit when the related switch is operated,
replace the regulator, otherwise check the
wiring and the switch.
