If the braking surface diameter exceeds specifications, the drum must be replaced. If the braking surface diameter is within specifications, drums should be cleaned and inspected for cracks, scores, deep grooves, taper, out of round and heat spotting. If drums are cracked or heat spotted, they must be replaced. Mi...

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 ...

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.
DEPRESSURIZING POWERMASTER III
The Powermaster III must be depressurized prior to performing any service operations.
