Hydraulics uses what as its non-compressible medium

Two technicians are discussing drum brake shoes. Technician A says that forward and​ rear-facing shoes are the same and can be installed in either position on any drum brake system. Technician B says that the darker color linings should always be placed toward the front of the vehicle. Which technician is​ correct?

Technician A says that the anchor pin​ (shoe anchor) is used to hold one end of the primary and secondary shoe return springs. Technician B says that the shoe anchor prevents the brake shoes from rotating with the drum when the brakes are applied. Which technician is​ correct?

Which lining does most of the braking on a​ dual-servo brake?

Which lining does most of the braking on a​ leading/trailing brake?

The brakes on a​ dual-servo drum system are designated as​ ________.

​________ action uses drum rotation to force the brake shoe outward and wedge it tightly against the brake drum.

When removing the Brake line from a Wheel Cylinder, what tool should be used?

As a general rule, how often should brakes be checked?

Technician A says to make the finish cut at the slowest speed when machining brake drums. Technician B says that the drum should not exceed its discard diameter. Who is correct?

Duo-Servo brakes adjust:

Leading Trailing brakes are adjusted:

On a Duo-Servo drum brake, when compared to Primary shoe linings, the Secondary shoe linings are:

Technician A says that all modern brake linings are bonded to their shoes. Technician B says that some brake linings are riveted to their shoes. Who is correct?

After assembling a drum​ brake, it is discovered that the brake drum will not fit over the new brake shoes. Technician A says that the parking brake cable may not have been fully released. Technician B says to check to see if both shoes are contacting the anchor pin. Which technician is​ correct?

Technician A says that hard spots in a brake drum should be removed using a​ carbide-tip machining tool. Technician B says the drum should be replaced if hard spots are discovered. Which technician is​ correct?

New rear brake shoes were replaced on a​ rear-wheel-drive vehicle equipped with front disc brakes and rear drum brakes. During the test drive smoke was observed coming from both rear wheels. Technician A says that this is normal because the new linings always smoke when first heated due to the resins in the lining. Technician B says that the parking brake cable may not have been fully released causing the brakes to drag. Which technician is​ correct?

Which is the most likely cause of chatter marks on the friction surface of a brake drum during​ machining?

New wheel cylinders are being installed. Which operation is not​ required?

Which of the following is part of a star wheel in a drum brake?

Drum brake return springs can be which type?

_____________________ do just what their name suggests; they hold the brake shoes against the backing plate

__________________ are used to return links and levers on the parking brake system or the self-adjuster mechanism.

Which type of brake lining is typically used on light-duty vehicles?

Which type of brake lining is typically used on heavy-duty vehicles?

Which of the following can be found on a typical drum brake shoe?

True or False. The composition of the lining material affects brake operation. Materials that provide good braking with low pedal pressures tend to lose efficiency when they get hot.

The ___________________ gets its name from using the servo action in both the forward and the reverse direction.

___________________ are installed so the direction they are applied is the same as the forward rotation of the drum.

___________________ are installed so the direction they are applied is opposite of the forward rotation of the drum.

Which of the following is a typical component of a drum brake system?

Which type of drum is typically used on common passenger vehicles?

Wheel cylinders typically contain which of the following?

True or False. The bleeder screw is a hollow screw. It has a taper on the end that mates with a matching tapered seat in the wheel cylinder.

Which of the following is a recommended tool for removing brake lines from a wheel cylinder?

Tech A says that it is a good practice to research any technical service bulletins for any brake system complaint. Tech B says that it is common practice to test-drive a vehicle even if the brake pedal goes to the floor. Who is correct?

Tech A says that a brake spoon is used to adjust brake shoes when the drum is installed. Tech B says that a brake hold-down spring tool is used to remove and install hold-down springs. Who is correct?

Tech A says that when removing a hubless-style drum, you should first make matching marks on the drum and hub for reinstallation in the correct position. Tech B says that a center punch can be used to mark the position of the drum to hub. Who is correct?

Tech A says that it is not necessary to clean any nicks, burrs, or debris from a brake drum surface before mounting the brake drum on a brake lathe. Tech B says that you should research the brake lathe manufacturer's procedure for properly refinishing a brake drum. Who is correct?
