The school bus driver was returning to the bus compound when the brake pressure warning buzzer came on. She pulled to the gas pumps and stopped her bus(she had brakes at this time). The driver stood up and was about to exit the bus when she heard a "pop" the electric brake assist came on. Brake pedal rod came out of the power assist head. Rod was still connected to the brake pedal. This is the second one of these to come apart. The other was reported to nhtsa june 2000. The local dealer can not explain why the rod came apart. They replaced the entire unit and sent it to the factory? i have (40) 1998 buses. I am very concerned this will happen again. We inspected the buses and there is no way to tell when/if the rod will fall out. When this rod falls out you have no brakes! the pedal falls to the floor.
Steering locks or requires more effort to turn when the steering wheel is turned and the brake pedal is firmly depressed. This may also be the reason we have so many brake pressure alarms going off. The driver often ignores the alarm or turns the bus off and restarts it to reset the alarm.all 40 of our 1998 buses have the same defect.
