ABSTRACT:
An improved friction brake system for a transit vehicle is disclosed. The conventional friction brake system for a transit vehicle utilizes an integral service brake and emergency-parking brake actuator. The service brake portion is air powered while the emergency-parking brake portion is spring powered. It has been conventional to apply full service air brake and emergency spring brake during emergency stops. An accelerometer switch is typically connected in circuit with the service brake portion to prevent the service brake from turning on if their is sufficient deceleration. The accelerometer switch often does not react quickly enough to prevent the onset of the service brakes. The present invention utilizes a time delay switch to delay the onset of service brakes until after the spring-activated emergency brakes react.
