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)
Cylinder inspection
Refer to “engine top side disassembly” .
Refer to “engine top side assembly” .
Cylinder distortion
Check the gasket surface of the cylinder for distortion.
Use a straightedge and thickness gauge. Take clearance
readings at several places. If any reading exceeds the
service limit, replace t ...
Radiator cap inspection
Inspect the radiator cap in the following procedures:
remove the radiator cap. Refer to “cooling circuit inspection” .
Attach the radiator cap (1) to the radiator tester (2)
as shown.
Slowly apply pressure to the radiator cap.
If the radiator cap does not hold the pre ...
