AIRBRAKE SYSTEM - CONTINUED
The anitlock system is a computerized system that monitors even braking of all wheels at all times. It uses an electrical
sensor mounted in each brake assembly to count the number of revolutions per wheel. A computer module for each axle
receives an electrical signal and automatically varies the pressure through the relay valves and quick-release valve using
an air and electrically operated modulator valve to slow each wheel at the same rate of speed.
The vehicle uses a combination of plastic lines and flexible hoses designed to carry air under pressure to supply air
pressure to all air system components. See diagram (page 1-31) for location and routing of lines.
