Bleeding the rear braking system

A long travel and mushy feel of the brake pedal indicate that there is air
in the system and the brake needs bleeding.
Bleeding procedure is as follows:
- Remove reservoir cap (A) (21 mm wrench) and diaphragm and fill with fluid
(DOT 4).
- Attach a clear plastic hose to the calliper bleed valve (1) and place the other
end of the hose in a vessel.
- Press the pedal (2) fully down.
- Loosen the bleed valve and drain the fluid (only air at first), then slightly close
the valve.
- Release the pedal and wait a few seconds. Repeat the process until you see
only fluid coming out of the hose.
- Tighten the bleed valve to the specified torque and check fluid level (B) in the
reservoir before refitting the cap (A). If the bleeding procedure was performed
correctly, the pedal will no longer have that mushy feel. If not so, repeat the
H006221
procedure.
Fluid level inside the reservoir shall never drop below the minimum
notch during the bleeding procedure.
If brake lever or brake pedal feel mush after a fall or a repair result-
ing in loss of braking, bleed the circuit as described above.
Bleed valve tightening torque: 12-16 Nm, 1.2-1.6 Kgm, 8.8-11.8 ft/
lb.
