VEHICLE PREPARATION
•
Connect the bleeding unit to the reser-
voir of the braking system.
Max. filling pressure to be applied to the sys-
tem= 3 bar (300 kPa - 43.51 PSI).
PURGING PROCESS TO CHANGE THE BRAK-
ING SYSTEM FLUID
Connect the bleed bottle to the bleed screw of the
front calliper and open it.
•
Operate the bleeding unit and while the
system is being purged, top up the res-
ervoir with the new DOT 4 brake fluid;
keep doing this until clean oil begins to
flow out through the bleed tube.
•
Leave the screw open until the fluid in
the tube is clear and free of air bubbles.
•
Close the bleed screw.
•
Repeat this procedure on the remain-
ing bleed valves of the system and
close them all to the prescribed tight-
ening torque.
•
Remove the bleeding unit.
•
Always fill the reservoir up to the reference "MAX" and refit the cap.
•
Check the stroke and the sensitivity of both the lever and the brake pedal.
•
If after bleeding, the pedal or the lever stroke is too long, check that there are no leaks in
the braking system and if everything is ok, continue bleeding operations using Axone as
described.
•
Detach the bleed hoses and close the bleed screws again to the correct tightening torque.
