presence of air bubbles in the circuits.
Braki ng circuit :01 right Iront brake (Iig. 167)
• Turn the reservoir until the master-cylinder-re-
servoir assembly reaches the horizontal position.
• If
necessary, top up fluid reservoir .. A ... ensuring
that during the bleeding operation the fluid level
does not drop below the transparent section .
8y acting on caliper .. E .. :
1 Take off rubber caps " M .. and on drain plug " F ..
fit a transparent flexible pipe " G .. of which the other
end is plunged inlo a Iranspe:rent con tainer " H .. par-
tially Idled up with f.Uld of the same type.
2 Loosen drain plug " F ...
3 Pull handlebar control lever .. 8 .. and release It
slowly. waiting a few seconds before pulling it again .
Repeat the operation several times until airless fluid
comes out from the pipe at the container end .
4 Keep control lever .. a" fully pulled and tighten
drain plug " F .. . Then remove pipe .. G" and refit rub-
ber caps .. M .. on the drain plug .
If the air bleed ing operation has been carried out
correctly, the efficiency of the braking action will
be immediately fell after the initial movement of le-
ver «a .. .
If not, repeat the operation .
