BLEEDING THE BRAKING SYSTEM<br />
The air, when present in the hydraulic circuit, absorbs most<br />
of the pressure exerted by the brake pump and therefore reduces<br />
the effectiveness of the calliper action during the braking.<br />
The presence of air is signalled by the elasticity of the<br />
brake control and by reduced braking capacity.<br />
CAUTION<br />
Since these conditions would be extremely dangerous<br />
for the vehicle and for the pilot, it is absolutely<br />
important to bleed the hydraulic circuit after the reassembly<br />
of the brakes and the restoration of the<br />
normal conditions of use.<br />
• Remove pump cover (2).<br />
• Unscrew the two screws (3) of the brake fluid tank (4).<br />
• Remove the cover (5).<br />
IMPORTANT It is advisable to keep the fluid in the tank parallel<br />
to the ground (horizontally), in order not to spill it while<br />
topping up.<br />
• Remove the gasket (6).<br />
• Make sure that the fluid covers the glass (1) completely<br />
and top up if necessary.<br />
• Remove the protection cap (11) of the air valve.<br />
• Connect a transparent pipe (11) to the air valve (12).<br />
