Brake Basics
This system slows a vehicle using friction or resistance.
The braking system
What are the two types of hydraulic brakes used on automobiles?
Disc and drum brakes
Name the three main parts of a disc brake assembly.
Rotor, caliper, brake pads
What does ABS prevent during hard braking?
Wheel lockup
What is the most common type of brake fluid?
DOT 3
What type of braking recaptures kinetic energy and converts it to electrical energy?
Regenerative braking
Why is air in a hydraulic brake system dangerous?
Air is compressible, reducing braking efficiency
What part of a drum brake pushes the shoes outward?
Wheel cylinder
Which system helps maintain control during oversteer or understeer?
Electronic Stability Control (ESC)
Why does brake fluid level drop as pads wear?
Pistons move farther as pads wear
What is the main purpose of the braking system?
To slow or stop the vehicle safely
What process removes air from the brake system?
Brake bleeding
What component monitors wheel speed for ABS?
Wheel speed sensor
What system applies brakes automatically to avoid a collision?
Automatic Emergency Braking (AEB)
What contaminant makes the brake pedal feel spongy?
Air
What type of system electronically controls friction and regenerative braking?
Brake-by-Wire (BbW)
What principle explains why brake fluid transfers pressure evenly?
Fluid is non-compressible
What causes brake pedal pulsation in disc brakes?
Disc thickness variation (rotor runout)
Which system helps prevent rolling backward on a hill?
Hill Start Assist (HSA)
How often should brake fluid typically be changed?
Every 2-3 years
What force resists motion between two touching objects?
Friction
What component converts mechanical force from the brake pedal to hydraulic pressure?
Master cylinder
What is the function of the caliper?
Converts fluid pressure to mechanical motion of pads
What system adjusts throttle and braking to maintain traction during acceleration?
Traction Control System (TCS)
What property of brake fluid helps prevent corrosion and lubricates parts?
Hygroscopic property
