Trivia Quiz: How Much Do You Know About Anti-lock Braking System?

Each of the above is a part of the pressures and force associated with a hydraulic system.

Each of these can be used to test the contamination level of brake fluid.

The brake hoses can be connected to the caliper by either directly screwing into it, or by attaching it with a banjo fitting.

All of these functions are dependent upon either a sufficient amount of brake fluid, or sufficient and equal amounts of hydraulic pressure in the system.

The dust shield will help is keep all of these contaminates from the disc braking system.

The wheel speed sensors are responsible for telling the EBMC the speed of each wheel it is observing.

All of the above could be effected by a leak in the brake hydraulic system, and could also effect satisfactory brake pedal height, travel, and free play.

Always use the anti-chatter / silencer band.

The brake switch operates the brake lights and/or it can notify the EBCM of brake pedal operation.

A wheel speed sensor could have any electrical fault.

Any damage to the tone wheel will effect the validity of its use.

Both of these are options for brake pad wear indication.

TSB's can help in repairing many brake and non-brake related repairs. If the brake pedal goes to the floor, should that vehicle be driven?

Both a DVOM and an oscilloscope can be used to test a wheel speed sensor.

Brake fluid is better than water in the sense that it has a higher boiling point and a lower freezing point, but it does have the down fall of absorbing water, being hygroscopic.

Most modern master cylinder reservoirs now have two, independent chambers to allow for operation on two different hydraulic circuits.

Any electrical fault may limit the function of the brake lights.

The ABS warning light is most often yellow. It is a less threatening situation for the vehicle occupants than low brake fluid.

Electronic braking systems can have two, three or four channels.

Starting all fasteners by hand is best practice. Some hubcaps are held in place by the lug nuts.

Steel brake lines and hoses are the only tubes used to carry brake fluid throughout the hydraulic brake system.

The banjo fitting includes the bolt, washers to seal the connection, and the bolt itself.

A special tool is required when retracting a piston on a caliper with an integrated parking brake.

Two actions comprise the self energizing, duo-servo drum brake system.

Many vehicles now offer a by pass switch to deactivate the EBCM by the driver.

If there is a detected fault with the EBCM system, there will be a solid light to notify the driver of the fault.

A brake shoe has all of these.

The push rod does not create hydraulic force. It is merely an intermediate component, responsible for transferring force to the remaining brake system.

Proportioning valves are either pressure or load sensitive and reduce the pressure to the rear wheels under normal braking. They also adjust rear brake pressure depending on the height, amount of weight, in the vehicle.

Both of these will cause brake pedal pulsation, but when the ABS operates, it's considered normal.

Rotating calipers do not exist.

Yes, peeling the seal back slightly to inspect a wheel cylinder is correct, but no fluid should be seen. If found, it is bad and needs to be replaced.

Both vehicle speed and wheel speed sensors can report the vehicle speed to the vehicle computer. In some cases, the terms are synonymous

Which way does a wheel turn when traveling forward? The leading shoe touches the drum first.

Both of these provide pressure to all sides of the fitting, and allows the technician to get around line to do so.

The seal for the piston is a stationary, square cut seal.

Fixed calipers are rigidly bolted in place. Sliding calipers do only have one piston.

Drums can not be refinished while they remain installed.

Bearings that are serviceable should always be serviced when doing a brake job. Non-serviceable bearings should be inspected for excess play during maintenance inspections and brake jobs.

Burnishing pads will help extend pad life and to reduce potential noise.

A special tool is required to push the piston back in and it does line up with the grooves in the face of the caliper piston.

When removing brake components, always index the parts. Using a center punch is ok to make these marks.

Brake master cylinders should always be bled before being installed into a vehicle.

Always use a star pattern to ensure the wheel is uniformly tightened to the hub.

The wheel cylinder is not responsible for applying the parking brakes.

Bench bleeding does not remove contaminants from the brake fluid system; it only removes air and prepares the master cylinder for installation into the vehicle.

Nothing is to be between the toothed wheel and the sensor itself.

Both EBCM and non can be bled in the same manner, but some vehicles have an EBCM which is susceptible to allowing air to enter it, thus, requiring a scan tool to properly bleed the system.

Typical wheel speed sensors produce voltage, so to test for supply voltage would be an invalid test.

Excessive thickness variation will cause surging.
