Disc Brakes
What is the primary function of disc brakes in a vehicle?
To slow down or stop the vehicle by applying friction to the brake rotors.
Where are drum brakes typically located in a modern vehicle?
Usually on the rear wheels
What is the primary purpose of the steering system in a vehicle?
To allow the driver to control the direction of the vehicle
What does "toe" refer to in wheel alignment?
The angle of the wheels in relation to each other when viewed from above.
What is the primary function of a vehicle's suspension system?
To provide a comfortable ride and maintain vehicle control by absorbing road shocks.
Name the main components of a disc brake system
Brake rotor, caliper, brake pads, and brake lines.
What are the main components of a drum brake system?
Brake drum, brake shoes, wheel cylinder, and return springs
Name three main components of a typical steering system.
Steering wheel, steering column, and steering gear/rack
What is "camber" in relation to wheel alignment?
The angle of the wheel in relation to the vertical axis when viewed from the front or rear
Name three main components commonly found in a suspension system.
Springs, shock absorbers (dampers), and linkages/control arms.
What type of force does the brake caliper apply to the brake pads?
Clamping force
How does a drum brake system slow down a vehicle?
The wheel cylinder pushes the brake shoes outward against the inside of the rotating drum, creating friction.
What type of steering system uses hydraulic pressure to assist the driver?
Power steering
What is the function of a tie rod end?
It connects the steering rack or center link to the steering knuckle, aIt connects the steering rack or center link to the steering knuckle, allowing movement and adjustmentllowing movement and adjustment
What is the purpose of springs in a suspension system?
To support the weight of the vehicle and absorb initial impacts from the road
What happens to the kinetic energy when the brakes are applied?
It is converted into thermal energy (heat)
What is "brake fade" and why are drum brakes prone to it?
Brake fade is the reduction in braking power due to overheating. Drum brakes are more enclosed, which traps heat and makes them more prone to fading.
What is the function of the steering knuckle?
It connects the suspension to the wheel hub and allows the wheel to pivot.
What is Electronic Power Steering (EPS)?
A system that uses an electric motor to provide steering assistance instead of a hydraulic pump.
Describe the difference between independent and dependent suspension systems.
Independent suspension allows each wheel to move independently, while dependent suspension connects wheels on the same axle.
Why are disc brakes more effective in wet conditions compared to drum brakes?
Disc brakes can dissipate water and debris more effectively, maintaining better friction
What is the function of the return springs in a drum brake system?
To pull the brake shoes back away from the drum when the brake pedal is released.
What is the purpose of "wheel alignment"?
To ensure that the wheels are set to the correct angles relative to each other and the vehicle's body, optimizing handling and tire wear.
During an inspection you find the power steering level low, What is the first step?
Check the system for leaks.
What is the function of a stabilizer bar?
To reduce body roll during cornering, improving stability.
