Vehicle: 1990 Chevrolet Camaro RS 5.0 V8 GAS
Two basic types of power assist mechanisms are used: vacuum assist diaphragm assemblies, which use engine vacuum or, in some cases vacuum pressure developed by an external vacuum pump. The second type is a hydraulic pressure assist mechanism, which use pressure developed by an external pump (usually the power steering pump). Both systems act to increase the force exerted on the master cylinder piston by the operator. This in turn increases the hydraulic pressure delivered to the wheel cylinders, while decreasing driver effort necessary to obtain acceptable stopping performance.

Vehicle: 1990 Chevrolet Camaro RS 3.1 V6 GAS
DUAL MASTER CYLINDER
Front & Rear Split System
When the brake pedal is depressed, both the primary (front brake) and the secondary (rear brake) master cylinder pistons are moved simultaneously to exert hydraulic fluid pressure on their respective systems,Figs. and .
If the rear (secondary) brake system fails, initial brake pedal movement will cause the unrestricted secondary piston to bottom in the master cylinder bore. Primary piston movement will displace hydraulic fluid in the primary section of the master cylinder to actuate the front brake system.
If the front (primary) brak...

Vehicle: 1990 Chevrolet Camaro IROC-Z 5.7 V8 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 ...

Vehicle: 1990 Chevrolet Camaro RS 5.0 V8 GAS
DESCRIPTION
This booster is a single diaphragm, vacuum suspended unit with a lightweight cast alloy housing,Fig. . Vacuum is applied to the front and rear housings. When the brake pedal is released, negative pressure is equalized on both sides of the diaphragm and power piston assembly. Spring tension holds the piston at the rest position. When the brakes are applied, the atmospheric port in the power piston is opened. Negative pressure in the front chamber pulls the diaphragm and vacuum piston assembly, reaction disc and output rod forward. Pressure on the master c...

Vehicle: 1990 Chevrolet Camaro RS 3.1 V6 GAS
When a premature rear wheel slide is obtained on a brake application, it usually is an indication that the fluid pressure to the rear wheels is above the 50% reduction ratio for the rear line pressure and that malfunction has occurred within the proportioning valve.
To test the valve, install gauge set shown in Fig. in brake line between master cylinder and proportioning valve, and at outpu...
