Auto 06 - Stop! Write This Quiz, Pt 1
The first of two quizzes on brakes and brake systems.
- 1.Why are front brakes changed more often than rear brakes?
- A.
Disc brakes aren’t as durable as drum brakes
- B.
It’s not true - rear brakes are changed more frequently
- C.
Front brakes have to work harder than rear brakes
- D.
Brakes don’t need to be changed
- 2.How many pistons are found in a master cylinder?
- A.
One - the slave cylinder distributes the pressure
- B.
Two - one for each system
- C.
Three - in case the first two fail, there is a back up
- D.
Four - one for each wheel
- 3.Which type of disc brake has a piston on each side of the rotor?
- A.
Fixed caliper
- B.
Floating caliper
- C.
Sliding caliper
- D.
All disc brakes have pistons on each side of the rotor
- 4.How is rotor wear accommodated for on disc brakes?
- A.
Return springs
- B.
Square-cut O-ring
- C.
Hydraulic pressure
- D.
Centripetal force
- 5.The friction material on disc brakes are called what?
- A.
Pads
- B.
Shoes
- C.
Stoppers
- D.
Asbestos
- 6.The two main types of drum brakes are called Duo-Servo and...
- A.
Single-Servo
- B.
Shoe-type
- C.
Non-Servo
- D.
Haploid
- 7.What is the function of the metering valve?
- A.
Measures how much brake fluid needs to be added to master cylinder
- B.
Measures amount of hydraulic pressure is applied to front and rear brakes
- C.
Measures amount of hydraulic fluid lost to evaporation
- D.
Delays front brake application until rear brakes are applied
- 8.What does the proportioning valve do?
- A.
Automatically mixes water into brake fluid for correct dilution
- B.
Equalizes amount of hydraulic pressure is applied to front and rear brakes
- C.
Produces ‘feedback pressure’ to brake pedal.
- D.
Limits hydraulic pressure to rear brakes to prevent wheel lock-up
- 9.Pressure differential switch does what?
- A.
Detects loss of pressure (leak) in a circuit and turns on warning light.
- B.
Electronically controls hydraulic pressure to front and rear brakes.
- C.
Electronically delays the application of the rear brakes
- D.
Electronically delays the application of the front brakes
- 10.Why are drum brakes easier to use as parking brakes than disc brakes?
- A.
They provide better friction for difficult parking situations
- B.
The hydraulics are less likely to fail than on disc brakes
- C.
It is easier to activate drum brakes using mechanical means
- D.
The front brakes are used more in parking brake situations
