Friction & Fundamentals
This physical principle is essential for brakes to slow or stop a vehicle.
What is friction?
The type of brake system that uses fluid to transmit force.
What is a hydraulic brake system?
Converts foot pressure into hydraulic pressure.
What is the master cylinder?
Assists the driver in applying braking force
What is a brake booster?
Includes checking fluid, pads, and hoses for condition and function.
What is routine brake service?
Brake systems convert this type of energy into heat.
What is kinetic energy?
The component responsible for storing and pressurizing brake fluid.
What is the master cylinder?
These valves help regulate brake pressure to front or rear wheels.
What are metering and proportioning valves?
Type of master cylinder designed for quicker brake application in modern systems.
What is a quick take-up master cylinder?
Involves ensuring proper linkage between pedal and master cylinder.
What is pushrod adjustment?
The coefficient of friction is affected by this environmental factor.
What is temperature?
The two common types of brake assemblies.
What are disc and drum brakes?
These parts are pressed against a rotor or drum to slow the vehicle.
What are brake pads and brake shoes?
This system replaces manual handbrakes with a motorized function.
What is an electric parking brake?
A flexible component often inspected for cracks, bulges, or leaks.
What are brake hoses?
This brake component is designed to maximize surface contact and friction.
What is the brake pad (or shoe)?
The principle that pressure applied to a fluid in a confined space is transmitted equally in all directions.
What is Pascal's Law?
This component returns the brake pedal to its original position.
What is the return spring (or pedal return spring)?
Some systems use this pressure source instead of vacuum for boosting brake force.
What is hydraulic pressure (as in hydroboost systems)?
Air in the brake lines leads to this condition.
What is a spongy brake pedal (or brake fade)?
Two main types of braking friction include sliding and this other type.
What is rolling friction?
This valve prevents the rear brakes from engaging too early, reducing the risk of skidding.
What is a proportioning valve?
This component ensures brake fluid does not leak past the piston in the master cylinder.
What is the primary cup seal (or piston seal)?
This system prevents wheel lockup during emergency braking.
What is an anti-lock braking system (ABS)?
This procedure removes air from the hydraulic system after service.
What is brake bleeding?
