Breaks

Front wheel drive vehicles typically use

• Front/rear split brake systems

• Diagonally split brake systems

• Equally nembers of each

• Side to side split brake systems

Technician a says that the brake fade occurs if the break creates more heat then they can dissipate. Technician B says that brake fade occurs by a fast dissipation of heat in the brake system that causes a glazing on the brake linkage. Who is correct

• A

• B

• Both

• Neither

What percentage of the brake force comes from the rear Breaks in a typical front wheel drive vehicle

• 10

• 30

• 50

• 70

Technician a says that if friction is to love the brakes may require excessive pressure. Technician B says that if the friction is too low and the brakes may be overly sensitive. Who is correct

• A

• B

• Both

• Neither

If a 2 in. master cylinder piston moves 1 inch during braking how far will a 4 in. caliper piston

• 2

• 1

• 1/2

• 4

The more weight a moving vehicle has

• More kinetic energy it possesses

• The greater the tire footprint is

• Less heat is needed to move the vehicle

• The less stopping power it requires

On vehicles with rear drum brakes and front disc brakes, the metering valve ensures that drum brakes receive hydraulic pressure

• Slightly before the disc brakes

• Slightly after the disc brakes

• Only during hard stops

• Only if disc brake fails

Which of the following statements is true

• The smaller the tires diameter is the larger the footprint is

• The larger the tires diameter is the less breaking power is required

• The larger the tires diameter is the smaller is footprint is

• The larger the tires footprint is the more stopping power can be applied at the tires contact point with the road

Pressure differential valves are spring-loaded plunger valve pressure differential valves are spring-loaded plunger valves that are used to turn on dashboard warning lights if hydraulic pressure is lost in

• Front brake systems only

• Rear brake systems only

• Either front or rear brake systems

• Wheel cylinders or calipers only

Proportioning valve

• Preventing the front desk breaks from a plane before the rear drum brakes

• Prevent rear brake lock up during heavy braking

• Equalize the fluid pressure between the two sides of a diagonally split brake system

• Equalize The fluid pressure between the two sides of a front/rear split brake system
