Disk Brakes - APRILIA SXV / RXV 450 550 Use And Maintenance Book

MAINTENANCE
3.1.9.

DISK BRAKES

DANGER
The brakes are the parts that most ensure your
safety and for this reason they must always be
perfectly working; check them before every trip.
A dirty disk will soil the pads, leading to loss of
braking efficiency.
Dirty pads must be replaced, while dirty disks
must be cleaned with a high-quality degreaser.
The brake fluid must be changed every year by
an aprilia Authorized dealer.
Use brake fluid of the type specified in the
lubricant chart, see (LUBRICANT TABLE).
NOTE This vehicle is provided with disk brakes with two -
front and rear- braking systems having separate hydraulic
circuits.
The front braking system is with single disk (left side).
The rear brake uses a single disk (right side).
The following information refers to a single braking system,
but is valid for both.
When the disk pads wear out, the level of the fluid inside
tank (1 – 2) decreases to automatically compensate for their
wear.
The front brake fluid reservoir (1) is mounted near the front
brake lever mount.
The rear brake fluid reservoir (2) is built in the master
cylinder fixed to the frame, on the right, next to the swing
arm.
NOTE Halve maintenance intervals if you are riding in rainy
or dusty conditions, on rough road surfaces or when the
vehicle is used in competitions.
Before departure, check the brake fluid level in the reservoirs
(1 – 2), see (CHECKING BRAKE FLUID LEVEL) and the
wear of the pads, see (CHECKING THE BRAKE PAD
WEAR).
WARNING
Never use your vehicle if any portion of either brake
system is leaking.
WARNING
Do not add any additives or other substances to the
brake fluid.
