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 ...

DISC BRAKES, GENERAL MOTORS -> General Information -> BRAKE DISC SERVICE
Vehicle: 1990 Buick Electra Park Avenue Ultra 3.8 V6 GAS
Servicing of disc brakes is extremely critical due to the close tolerances required in machining the brake disc to insure proper brake operation.
The maintenance of these close controls of the shape of the rubbing surfaces is necessary to prevent brake roughness. In addition, the surface finish must be non-directional and maintained at a micro inch finish. This close control of the rubbing surface finish is necessary to avoid pulls and erratic performance, and to promote long lining life and equal lining wear of both left and right brakes.
In light of the foregoing remarks, ref...
