Miscellaneous
What tool is used to measure the external and internal dimensions of an object, including its outside and inside diameters?
vernier caliper
What is a glycol-based hydraulic fluid used in brake systems?
brake fluid
What is the foot lever for operating the master cylinder and power booster called?
brake pedal assembly
What is the replaceable wear material in disc brakes?
brake pad lining/friction material
This component is used to push the brake shoes against the brake drum?
Wheel cylinder pistons
Before taking a measurement, what should you do to ensure the digital caliper is accurate?
zero it out
What are brake rotors and drums are normally constructed of?
cast iron
What part of the brake system pushes the brake pads against the rotor to create friction and slow down the vehicle?
brake caliper piston
What keeps road dirt and water off the caliper piston and the wall of the cylinder?
piston dust boot
What pulls the brake shoe from the drum when the brakes are released?
return springs
A tool used to apply a specific, calibrated amount of rotational force to a fastener to ensure it is tightened correctly.
torque wrench
What is the process of removing air from a vehicle's brake lines and cylinders?
bleeding brakes
What pressurizes the fluid in the brake system when the brake pedal is applied?
master cylinder piston
What allows air to be removed from the hydraulic brake system?
bleeder screw
What is used to prevent the shoes and hardware from spinning inside the brake drum when the brakes are applied?
anchor pin
In drum brake systems, a valve that maintains pressure in the wheel cylinders slightly above atmospheric pressure so air does not enter the system through the seals in the wheel cylinders.
Residual pressure valve
The amount of friction between two surfaces is expressed as the:
coefficient of friction
A hollow bolt that allows brake fluid to flow through it to the brake caliper
Banjo bolt
What prevents pressure leakage between the piston and the cylinder?
piston seal
Type of drum brake that has a self-energizing
force that is transferred from one shoe to the other
duo-servo
The port that connects the reservoir to the cylinder, just barely ahead of the primary cup
Compensating port
Assists in maintaining a reserve of system pressure in a hydraulic brake booster
accumulator
The valve that reduces rear brake pressure when the vehicle is lightly loaded and allows higher pressure when it is heavily loaded
Load-sensitive proportioning valve
A caliper that is bolted securely to the steering knuckle and has pistons on both sides of the rotor is called?
Fixed caliper
A valve used on vehicles equipped with older rear drum/front disc brakes to delay application of the front disc brakes until the rear drum drum brakes are applied
metering valve
