Total questions: 30
Worksheet time: 3600secs
Hydraulics are based on the concept that:
Fluid is incompressible
Fluid pressure is always unequal
Fluid always takes the path of greatest resistance
None of the above
Hydraulics can increase:
Force only
Torque only
Both Force and Torque
Neither Force nor Torque
Hydraulic force is created in the ______________ and transmitted through the brake lines to the wheel cylinders.
Brake Pedal
Master Cylinder
Brake Booster
Force Multiplier
An advantage of using a tandem (or double) piston master cylinder is that:
The vehicle will stop twice as fast
The tandem cylinder makes it leak proof
It is safer, a fault in one circuit will not cause complete failure
All of the above
Brake fluid is primarily composed of:
Water
Oil
Molybdenum
Glycol
Brake fluid is hydroscopic (attracts water) which can cause:
Rust in the brake system
Lower boiling point in the fluid
A spongy brake pedal
All of these answers
Brake Fluid should always come from a sealed container
True
False
Brake fluid is universal - so long as it has a DOT number, you can use it in any car.
True
False
A lower level of brake fluid in the reservoir is completely normal with wear of brakes.
True
False
Drum brakes can be actuated:
Mechanically
Hydraulically
Electrically
All of these
Drum brakes create a stopping action by creating friction between:
Pads and Rotors
Pads and Drums
Shoes and Drums
Shoes and Rotos
One advantage of Drum Brakes is that they are __________, so they need less power to operate.
Easily cooled
Self energizing
Simple
Light
Brake Fade causes a loss in drum braking due to:
excessive application
loss of fluid
loss of brake lining
too little pressure
Which drum braking system is most often used on rear wheels due to its equal effectiveness in both forward and reverse?
Leading - Trailing Shoe
Twin Leading Shoe
Duo Servo
Single Leading Shoe
A duo servo braking system has
different sized linings on each shoe
equal sized linings on each shoe
no linings on any shoes
pads only
Most modern vehicles us a ________________ to multiply the force from the brake pedal to the master cylinder using engine vacuum.
Fluid pump
Brake Booster
Computer system
Mag drive
A Park brake (or emergency brake) is a(n) _____________ type braking system
Hydraulic
Air
Mechanical
Electric
Hand brakes (or foot emergency brake) provide braking action to:
Front brakes only
Rear brakes only
All Front and Rear brakes
One Front and One Rear brake
If the brake system becomes contaminated with bad fluid or wrong fluid, you must:
Drain the system and refill
Drain and Flush with a suitable chemical, then refill
Replace all the seals in the brake system
Nothing - the system automatically compensates
The Master Cylinder is bigger (more surface area) than the Wheel (or Power) Cylinder
True
False
What is this part?
Wheel stud
Wheel cylinder
Wheel bearing
Starter
