IMPORTANT
Q
• The shuttle lever and main change lever are shift in
“NEUTRAL” position.
• Set the parking brake lever to “ON” position.
• Fill the transmission fluid to the equalizer and master
cylinder when overhaul the master cylinder assembly.
CAUTION
• Take care to hot part such a muffler and rotating part of
engine during air bleeding procedure.
NOTE
Q
• While bleeding, run the engine at low speed to keep enough
oil in the master cylinder assembly.
• Connect the vinyl pipe (2) of R.H. side to the air bleeder (4)
at trailer brake valve (3).
1. Disconnect the brake pipes (1) from the master cylinder.
2. Move the brake pedal up and down by hand. At this time, when
raising the pedal, close the master cylinder outlet by a finger, and
when lowering, release the finger.
Repeat this operation several times. (Prepare the oil can.)
3. After bleeding the master cylinder, install the front brake pipes.
4. After installing the vinyl pipe (2) to the bleeder loosen the bleeder
two turns.
5. Move the brake pedal up and down.
Repeat this motion until air bubble in brake oil disappears.
After bleeding, tighten the bleeders firmly.
(Reference : Importance of Bleeding)
• If the air mixes in the brake hydraulic circuit, poor or no braking
force is obtained due to compress the air even when the brake
pedal is pressed.
Accordingly whenever the hydraulic brake system is
disassembled, be sure to bleed after reassembling.
