What does the brake over-ride function do?

The brake over-ride function is primarily designed to address situations involving air brake failure, allowing the operator to release the parking brake safely in such emergencies. This function is crucial because air brake systems rely on compressed air to operate properly. If there is a malfunction that causes a loss of air pressure, the parking brake may engage automatically to prevent the vehicle from moving. The brake over-ride function provides bus operators with the means to safely disengage the parking brake, enabling them to regain control of the vehicle in critical situations.

This functionality is essential for maintaining safety on the road, especially in scenarios where immediate action is required to prevent accidents. Understanding how to utilize the brake over-ride helps operators manage unexpected failures effectively, ensuring both their safety and the safety of passengers.
