Air trapped in the brake fluid circuit acts like a cushion to absorb a large proportion of the pressure developed by the master cylinder and thus interferes with the full braking performance of the brake caliper. The presence of air is indicated by “sponginess” of the brake lever and also by lack of braking force. Considering the danger to which such trapped air exposes the machine and rider, it is essential that after remounting the brake and restoring the brake system to the normal condition, the brake fluid circuit be purged of air in the following manner:
Caution handle brake fluid with care: the fluid reacts chemically with paint, plastic, rubber materials, etc. |
Front brake
Note if air is trapped in the master cylinder, bleed air from the master cylinder first in the same manner as follows. Refer to “front brake master cylinder assembly removal and installation” . |
Note while bleeding the brake system, replenish the brake fluid in the reservoir as necessary. Make sure that there is always some fluid visible in the reservoir. |
Tightening torque air bleeder valve (front caliper): 7.5 N·m (0.75 Kgf-m, 5.5 Lbf-ft)
Rear brake
Note the difference of bleeding operation from the front brake is that the rear master cylinder is actuated by a pedal. |
Tightening torque air bleeder valve (rear caliper): 6 n·m (0.6 Kgfm, 4.5 Lbf-ft)
Drive chain cleaning and lubricating
Clean and lubricate drive chain
every 1 000 km (600 miles)
Clean and lubricate the drive chain in the following
procedures:
clean the drive chain with kerosine. If the drive chain
tends to rust quickly, the intervals must be
shortened.
Caution
do not use trichloroethyle ...
