Tech A states that the band brake system worked well in the reverse direction. Tech B states that the band would try to unwind in the forward direction. Who is correct?

Tech A states that designers can vary the size of the master cylinder to increase or decrease the force applied by a brake. Tech B states that the master cylinder of a brake system must always be of the same size. Who is correct?

Static friction is resistance between nonmoving surfaces and is present in which type of brakes?

Which of the following is MOST likely to be a parking brake system on a vehicle?

The air pressure for air brake systems comes from an engine-driven air compressor that pumps air into storage tanks.

Which of the following variables is related to pressure and force in a hydraulic system?

On a front-wheel drive vehicle, a load of about _______ on the rear wheels cannot provide enough braking force to stop the vehicle.

The brake booster receives approximately ____ of vacuum from the intake manifold.

Hydraulic boosters are always completely separate components from the master cylinder.

The hydraulic braking system can be designed to optimize the output force at each of the ________.

Dual-diaphragm boosters apply, hold, and release _______ a single-diaphragm booster.

Tech A states that an issue that leads to liability is forgetting to properly tighten components. Tech B states that one can take shortcuts to save time while performing brake repair. Who is correct?

Having the proper brake pedal _______ helps to ensure that the brake pedal has enough starting height to fully apply force to the brakes even if one half of the hydraulic system is rendered useless by a leak.

When performing pressure bleeding of a brake hydraulic system, the bleeder screws on the wheel brake units can be _______ and bled or flushed of old brake fluid and air once the master cylinder is pressurized.

Because the vacuum normally comes from the intake manifold, a leaky power booster can affect the operation of the engine by changing the air/fuel mixture.

Technician A says that in a CAN-bus circuit, the parking brake sensor and the low brake fluid sensors send data over the CAN-bus network regarding their status. Technician B says that diagnosis involves using a scan tool capable of interrogating the system, a wiring diagram, and a DMM to perform specific tests. Who is correct?

Tech A says that the disc brake rotor is the main rotating part of the disc brake system. Tech B says that the disc brake pads are located in the disc brake caliper only. Who is correct?

A dial indicator may be used for measuring rotor:

If the vehicle is safe to drive, it is common practice to test-drive the vehicle to verify the customer concern.

One safe way to test whether a braking problem is at the front or rear brakes is to drive at a low speed and:

To perform a thorough inspection of brake pads, you should do all of the following EXCEPT:

Brake bleeder screws enable all of the following tasks to be performed EXCEPT:

Vacuum bleeding uses a vacuum bleeder to _______ the air and old brake fluid from the hydraulic braking system.

Select one:

Low brake fluid levels could be caused by _________.

The pressure bleeder usually mounts to the master cylinder reservoir and supplies a steady stream of ________ for bleeding or flushing.

Excessive vacuum is _______ a problem because the booster is designed to work using maximum engine vacuum.

The master cylinder must be checked for internal and external leaks under all of the following conditions EXCEPT _______.

Check the __________ to the power booster for signs of brake fluid, which would mean brake fluid is leaking past the primary piston in the master cylinder and the front seal on the power booster.

Inspect ________ for leaks, cracks, etc.
