Front Disc Brake - APRILIA SR 150 Manual

Maintenance

FRONT DISC BRAKE

The brake disc and pad wear is automatically compensated,
therefore it has no effect on the functioning of the front and
rear brakes. For this reason it is not necessary to adjust the
brakes. An excessively elastic brake lever stroke may
indicate the presence of air in the braking circuit or an
irregular brake operation. In this case, particularly
considering the importance of the brakes in terms of safety,
it is strongly recommended that you take the vehicle to
Piaggio 2W Authorized Dealer as soon as possible for the
appropriate checks.

Warning
Check brake pads for wear on a regular basis (as indicated
in the schedule maintenance tables). If the thickness of one
or both pads is in the region of 1mm, both pads must be
changed.
It is recommended to carry out this operation at an Piaggio
2W Authorized Dealer as soon as possible.
After fitting new brake pads do not use the vehicle until you
have activated the brake lever repeatedly to position the
pads and restore the lever stroke to its correct position.
Caution
Braking should begin after about 1/3 of the brake lever
stroke.
The presences of mud, sand, dirt etc on the road can
drastically reduce the life of brake pads. In order to avoid
this it is recommended to always wash the vehicle when
riding on these road conditions. Always keep the brake
caliper and brake disc clean.
