ASE A5 Brakes - 9W3 Test

Front

One of the outside brake pads on a floating caliper system is worn more than the other pads. This could be caused by: Binding caliper guide pin, Seized caliper pistons, a restricted brake hose, a stuck metering valve.

Back

Binding caliper guide pin

Front

The best place to find handling instructions for hazardous chemicals is the:

Back

MSDS sheet

Front

All of these could cause the brake warning lamp to illuminate EXCEPT: Parking brake being applied, low brake fluid, a hydraulic leak.

Back

worn brake rotors

Front

What supplies power needed for brake assist on diesel vehicles? Options: Intake manifold, vacuum pump, power steering pump, exhaust manifold

Back

power steering pump

Front

A car has a suspected stuck caliper. Technician A states that the square seal in the bore of the brake caliper is responsible for pulling the piston away from the rotor. Technician B states that a return spring is responsible for pulling the piston away from the rotor. Who is right?

Back

Technician A

Front

A vehicle is equipped with a caliper mounted parking brake (EPB). Which statement is true about this system? Before replacing brake pads the system should be placed into service mode, The system uses a bidirectional motor to pull a cable to apply the parking brakes, A storage capacitor is used to provide electric power in case of power loss, The use of an EPB motor eliminates the need for hydraulic lines to the rear brakes

Back

Before replacing brake pads the system should be placed into service mode

Front

Which of these is being measured in the setup shown? Rotor thickness, Rotor scoring, Rotor paralellism, Rotor run-out

Back

Rotor run-out

Front

All of these could cause a vehicle to pull to the right during braking EXCEPT: a failed proportioning valve, a seized caliper piston, a leaking brake line, a restricted brake hose

Back

a failed proportioning valve

Front

The brakes are being bled on a passenger vehicle with disc/drum brakes. Technician A says that the drums should be removed to perform the bleed procedure. Technician B says that the fluid in the master cylinder should be kept low during the bleed procedure. Who is right?

Back

Neither

Front

A vehicle's front brake pads, rotors, and wheel speed sensors were replaced. During the road test, a technician noticed that the ABS system energized (operated) during applications at low speeds. Which of these could be the cause? Incorrect brake pad material, Air trapped in the hydraulic system, Incorrect wheel speed sensor air gap, roughness on the caliper slide surfaces

Back

Incorrect wheel speed sensor air gap
