The frictional parts used to contact the rotor during braking to stop the rotor and stop the car
What is a brake pad
100
A system that uses a computer to determine if a wheel is locking up during braking and a control unit to pulse the brakes on the wheel that is in danger of locking up
What is the antilock brake system
100
The tendency of certain liquid chemicals to absorb moisture
What is hygroscopic
100
A brake failure when the pads or shoes grab and release the rotor or drum without releasing or applying extra force to brake pedal. May be caused by brake fluid on the friction material
What is grabbing
100
Speed sensors generate an electricl signal each time a tooh on a a toothed ring passes the sensor's magnet. This is another term for toothed ring
What is a tone wheel
200
The friction covered parts used in the drum brake system to stop the brake drum from rotating
What is a brake shoe
200
This type of antilock braking system works only on rear wheels and is frequently found on light trucks and vans
What is rear-wheel antilock or RWAL
200
This brake caliper is bolted stationarily and uses two or more pistons to apply the brake pads against the rotor
What is a fixed caliper
200
This is a brake failure where the brake pedal is hard to push, but there is little braking effect at the wheels. It is usually caused by overheated brakes.
What is a hard pedal
200
A valve used to lower the hydraulic pressure going to the rear drum brakes to ensure balanced braking
What is the proportioning valve
300
The hydraulic component of disc brakes that activates the brake pads that stop the rotor during braking
What is a caliper
300
A braking method of redirecting or transferring power from a spinning drive wheel to a wheel with more traction
What is traction control
300
This the a device that operates when the driver pushes on the brake pedal to force fluid under pressure to activate wheel brake units
What is a master cylinder
300
A brake failure where the pedal tries to move up and down while the driver is applying force to the pedal. Usually caused when the brake rotors' friction areas are not parallel or when a rotor is warped.
What is pedal pulsation
300
A disc brake caliper that has all of the applied pistons on one side causing the whole caliper to slide away from the brake rotor that applies the outer pad
What is a sliding caliper
400
A valve housing that contains different types of valves. Automotive use of this valve is usually found in the brake system
What is a combination valve
400
The typical ABS system on passenger vehicles are four-wheel antilock; with either 3 or 4 channels. 4 channel systems control the braking at these points
What is at each wheel
400
This is a brake valve that can change the amount of braking done on the rear wheel based on the load being carried
What is a load-sensing proportioning valve
400
A brake failure where the pedal feels bouncy when the brakes are applied. Caused by air trapped in the brake system
What is spongy pedal
400
A specially cut O-ring commonly used as a seal for disc brake caliper and caliper piston
What is a square-cut O-ring
500
Brake lines have two types of fittings, the newer ISO-type flare and this
What is a double flare fitting
500
Typical ABS systems on passenger vehicle are four-wheel antilock; with 3 or 4 channels. 3 channel systems control the braking at these points
What is each front wheel and the rear axle set.
500
A system of brakes used to prevent complete brake system failure in event of a leak
What is a diagonally split brake system
500
Force is measured in this unit, while pressure is measured in this, and area is measured in square inches
What is foot-pounds (ft.-lbs) and pounds per square inch (psi)
500
Pascal's formula force equals pressure times area (F = P x A) calculates the use of pressure to transmit
