Hydraulic Systems
Drum Brakes
100
This law of physics states that pressure applied to a confined fluid is transmitted equally in all directions.
What is Pascal’s Law?
100
This hydraulic component uses two pistons to push the brake shoes against the drum.
What is the Wheel Cylinder?
200
This type of brake fluid is silicone-based and should never be mixed with DOT 3 or DOT 4.
What is DOT 5?
300
This valve is responsible for reducing hydraulic pressure to the rear brakes during heavy braking to prevent rear-wheel lockup.
What is the Proportioning Valve?
400
A "low and spongy" brake pedal is a classic symptom of this being trapped in the hydraulic lines.
What is Air?
500
This component in the master cylinder allows fluid to return to the reservoir when the brake pedal is released.
What is the Compensating Port?
