Viper GTS V10-8.0L VIN E (1999)
Brake Fluid Pressure Sensor/Switch: Description and Operation
The hydraulic brake system on the Viper is vertically split. This means the Viper is hydraulically split from front to rear, with both front brakes on one
hydraulic system and both rear brakes on the other. Versus a conventional front wheel drive system which is diagonally split, having the left front and
right rear brake on one hydraulic system and right front brake and left rear brake on the other.
Differential Valve And Brake Warning Switch
Both systems are routed through, but hydraulically separated by a Pressure Differential Valve. The function of the Pressure Differential Valve is to
alert the driver of a malfunction in one of the brake hydraulic systems.
When the brake pedal is depressed and hydraulic pressure is lost in one system, the warning light switch will actuate the Red Brake Warning Light on
the instrument panel. At this point the brakes require service. However, since the brake hydraulic systems are split front to rear, the vehicle will retain
half of its stopping capability in the event of a failure in either half of the system.
NOTE: The warning light switch is the latching type. It will automatically center itself after the repair is made and the brake pedal is depressed.
The instrument panel bulb in the Red Brake Warning Light can be checked each time the ignition switch is turned to the start position or the parking
brake is set.
