The problem
THE HYDRAULIC BRAKE SYSTEM ON THESE BUSES USES TWO HYDRAULIC PRESSURE SWITCHES TO OPERATE THE BRAKE LIGHTS AND THE BRAKE BOOSTER PUMP. THE BRAKE PRESSURE WARNING LIGHT CAN ACTIVATE WHEN ACTUAL SYSTEM FAILURE HAS NOT OCCURRED.
Risk
A FALSE WARNING OF THE BRAKE PRESSURE WARNING LIGHT CAN CAUSE THE DRIVER TO IGNORE A WARNING WHEN AN ACTUAL PROBLEM EXISTS WHICH COULD RESULT IN AN ACCIDENT.
What owners should do
DEALERS WILL REPLACE THE TWO HYDRAULIC PRESSURE SWITCHES WITH ONE MECHANICAL SWITCH THAT IS ACTIVATED BY BRAKE PEDAL STROKE.
