BRAKE PEDAL TRAVEL
When the vehicle is stopped and the ABS is pressurized, it is possible to push the pedal, until it bottoms near the floor. This travel is normal while system is pressurized. Excessive travel occurs when braking action does not begin within the first 1.25 inches of pedal travel, while system is pressurized. Excessive pedal travel also exists when pedal travel exceeds 3 inches, when applying light pressure, while Powermaster III unit is depressurized.

HYDRAULIC BRAKE SYSTEM, GENERAL MOTORS -> COMPONENT DESCRIPTION -> BRAKE DISTRIBUTION VALVE & SWITCH -> BRAKE WARNING LAMP SWITCHES -> COMBINATION VALVE -> Failure Warning Switch -> Fluid Level Sensor -> Metering Valve -> Proportioning or Pressure Control Valve -> Testing Warning Lamp Operation
Vehicle: 1990 Oldsmobile Cutlass Supreme International 3.1 V6 GAS
BRAKE WARNING LAMP SWITCHES
There are four basic types of brake warning lamp switches as shown,Figs. through . When a pressure differential occurs between the front and rear brake systems, the valves will shuttle toward the side with the low pressure.
In the switch shown inFig. , movement of the differential valve forces the switch plunger upward over the tapered shoulder of the valve to close the switch contacts and light the dual brake warning lamp, signaling a brake system failure.
InFig. , the valve assembly consists of two valves in a common bore that are spring loaded ...
