Service Brakes
Your bus may be fitted with air disc brakes or air-powered drum type brakes, depending on the options chosen at the time of manufacture.
Although they perform the same task, you may feel a difference in braking characteristics. Air brakes may require additional wait time
before driving during warmup, to allow air system pressure to build to normal operation levels.
Antilock Braking System (ABS)
In a vehicle equipped with an antilock braking system (ABS), motion sensors detect the speeds at which the wheels move. These sensors
transmit this information to an Electronic Control Unit (ECU). If the wheels start to lock, the ECU signals the modulator assembly to regu-
late the brake pressure of each wheel.
An ABS indicator lamp on the dash (see “Indicator Light Panel” in Instrument Panel section) warns the driver of possible system faults
and provides blink code information to diagnose the system. If this light is activated during normal vehicle operation, the driver may
complete the trip, but the vehicle must be serviced as quickly as possible.
Regenerative Braking
A unique aspect of an electric bus is being able to charge the main batteries using the energy available in a moving vehicle. Your Blue Bird
Electric Bus comes equipped with a regenerative braking system. When the accelerator pedal is released, the electric motor will act as a
generator to slow the vehicle down while at the same time feeding energy back into the batteries. If the batteries are over 90% state of
charge (SOC), the regenerative braking effect will be limited.
