Brake Servo-Pressure Sensing Anti-Dive System - Honda GL1800 Service Manual

BRAKE SERVO-PRESSURE SENSING ANTI-DIVE SYSTEM

This motorcycle is equipped with the Linked Brake System (LBS). This system operates the anti-dive system on the left
front fork by utilizing fluid pressure generated in the secondary master cylinder.
The secondary master cylinder responds to braking forces generated by the lever and/or pedal. When either brake is
applied, the plunger is pushed by pressure from the secondary master cylinder and the anti-dive piston valve in the fork oil
passage moves to block the passage. As the flow of the fork fluid is reduced by movement of the piston valve, the system
reduces compression of the front fork and thereby controls the nose dive of the vehicle.
