GENERAL TECHNICAL INFORMATION

REAR BRAKE

BLEEDING
Any air trapped in the hydraulic circuit will act as a cushion
and take up most of the pressure applied by the master
cylinder; this will impair the operation of the brake callipers
and reduce braking efficiency.
A spongy feel of the brake lever and loss of braking mean
that there is air in the circuit.
DANGER
This is a dangerous condition that makes the
vehicle unsafe to ride; each time the brakes are
removed, it is essential to bleed the hydraulic
circuit once the brakes have been refitted and
the brake system is back to normal operating
conditions.
NOTE Place the vehicle on level ground before beginning
the bleeding
While bleeding the hydraulic circuit, top up the reservoir with
brake fluid as required. Ensure that there is always some
fluid in the reservoir throughout the process.
•
Remove the bleed valve rubber cap.
• Insert one end of a transparent plastic tubing inside the
rear brake calliper bleed valve and the other end in a
container.
• Remove the rear brake reservoir plug.
•
Push and slowly release of the rear brake lever several
times, then keep it pushed completely.
•
Slacken the bleed valve by 1/4 of a turn to let the brake
fluid drain into the container; this will remove any
tension from the lever and help it travel fully home.
•
Retighten the bleed valve before the lever is fully
squeezed in.
•
Repeat this process until the fluid draining into the
container is totally clear of air bubbles.
NOTE While bleeding the hydraulic circuit, top up the
reservoir with brake fluid as required. Ensure that there is
always some fluid in the reservoir throughout the process.
•
Tighten the bleed valve and remove the tubing.
•
Add brake fluid to the reservoir until the fluid has
reached the correct level.
•
Refit the rubber cap.
CHANGING THE PADS
•
Release the brake line and the throttle cable from the
ties.
