What are the primary components of a basic hydraulic braking system in a vehicle?
Brake pedal, master cylinder, brake lines/hoses, and wheel brake assemblies.
Engine, transmission, drive shaft, and wheels.
Steering wheel, suspension, exhaust system, and tires.
Battery, alternator, spark plugs, and fuel pump.
What is the primary function of a lever in a mechanical system?
To generate electricity.
To convert electrical energy into mechanical energy.
To increase force, increase travel, or change the direction of movement.
To store potential energy.
Which principle states that pressure applied to an enclosed fluid is transmitted equally throughout the fluid?
Newton's Law of Motion
Archimedes' Principle
Pascal's Law
Bernoulli's Principle
In a hydraulic system, how can a smaller force applied to a master cylinder piston result in a larger force at a slave cylinder piston?
By using a fluid that is highly compressible.
By ensuring both pistons have the same surface area.
By having a larger surface area on the slave cylinder piston compared to the master cylinder piston.
By increasing the length of the fluid line between the cylinders.
What are the primary components of most brake fluids?
Water and oil
Glycerin, alcohol, and additives
Petroleum and silicone
Acid and base
Which of the following is a key property of most brake fluids?
High freezing point
Corrosive to rubber
Absorbs water
Low boiling point
What type of friction is primarily involved in a vehicle's standard service brakes while moving?
Static friction
Rolling friction
Kinetic friction
Fluid friction
What phenomenon occurs when a brake drum overheats and expands away from the brake lining, leading to increased brake pedal travel?
Lining fade
Mechanical fade
Brake fluid vaporization
Rotor warping
What is considered an ideally balanced static weight distribution for a vehicle?
60% front, 40% rear
50% front, 50% rear
55% left, 45% right
70% front, 30% rear
When a car undergoes braking, how does its weight typically transfer?
From the front tires to the rear tires.
From the rear tires to the front tires.
From the left side to the right side.
From the right side to the left side.
What is the primary safety advantage of a divided braking system in a car?
It allows for more aggressive braking in all conditions.
It ensures that if one part of the system fails, the other part can still halt the vehicle.
It reduces the overall stopping distance of the vehicle.
It provides separate control for each individual wheel.
Which type of divided braking system is commonly used in front-wheel drive (FWD) vehicles to ensure straight-line braking even if one system fails?
Vertical or front/rear split system
Diagonal or X split system
L-split system
Tandem master cylinder system
