brake drum.

shoes.

wheel cylinder.

springs.

All of the following are true about brake discs, except:

the brake disc is normally made of aluminum.

they may be an integral part of the wheel hub

the ventilated disc has a series of ribs

they may be solid or vented.

_____ are frequently used to keep the brake pads from vibrating and rattling.

Anti-rattle clips

Technician A says newer vehicles use brake pad linings made of heat- resistant organic or semimetallic friction materials. Technician B says newer vehicles use pad linings made of asbestos. Who is right?

A only.

B only.

Both A and B.

Neither A nor B.

True or False? Disc brakes are like the brakes on a ten-speed bicycle.

true

Brake _____ and brake _____ transfer fluid pressure from the master cylinder to the wheel brake assemblies.

lines, hoses

Power brakes use _____ to assist brake pedal application

Both a booster and engine vacuum

an engine vacuum

atmospheric pressure

a booster

The _____ is a lever arm to increase the force applied to the master cylinder piston.

brake pedal assembly

push rod

master cylinder

firewall

When hydraulic _____ of different sizes are used, motion and force can be increased or decreased.

pistons

List the three principles that apply to the operation of a hydraulic system.

liquids in a confined area will not compress, but air in a confined area will compress; when pressure is applied to a closed system, pressure is exerted equally

A hydraulic system uses a(n) _____ to transmit motion and pressure.

liquid

Technician A says front-wheel-drive cars can have a very low braking ratio at the front wheels. Technician B says front-wheel-drive cars can have a very high braking ratio at the front wheels. Who is right?

B only.

A only.

Both A and B.

Neither A nor B.

How much braking power do the front wheel brakes handle?

60% to 70%

Technician A says a wheel cylinder assembly houses a hydraulic piston that is forced outward by fluid pressure. Technician B says a brake drum rubs against brake shoes to stop or slow wheel rotation. Who is right?

Both A and B.

A only.

B only.

Neither A nor B.

All of the following are parts of a disc brake assembly, except:

wheel cylinder.

caliper.

brake pads.

rotor.

_____ brakes are frequently used on the two front wheels of a vehicle. _____ brakes are often used on the rear wheels.

Disc, Drum

Technician A says lever action pushes a rod into the brake booster and master cylinder when the driver pushes on the brake pedal. Technician B says this produces hydraulic pressure in the master cylinder. Who is right?

Both A and B.

A only.

B only.

Neither A nor B.

With _____ brakes, a conventional hydraulic brake system is combined with an electric regenerative braking system provided by the hybrid’s driveline.

hybrid

Automotive ______________provide the means of using friction to slow, stop, or hold the wheels of a vehicle.
