When you are tense, your " own force " acts as a parking brake — you must disengage it first before you can move quickly.

# When the ABS system is in operation the driver will feel a pulsing in the brake pedal ; this comes from the rapid opening and closing of the valves.

When activated, some earlier ABS systems caused the brake pedal to pulse noticeably.

When the thicker section of the disc passes between the pads, the pads will move apart and the brake pedal will raise slightly ; this is pedal pulsation.

When this is not done properly the brake pads will see an uneven distribution of stress and heat, resulting in an uneven, seemingly random, deposition of pad material.

When braking force is applied, the act of abrasive friction between the brake pad and the rotor wears both the rotor and pad away.

When shoes press on the outside of the drum, it is usually called a clasp brake.

When working on brake systems of older cars, care must be taken not to inhale any dust present in the brake assembly.

When the brakes are not being applied, the piston is returned to its original position by the force of the brake shoe return springs.

When the brakes are applied, brake fluid is forced under pressure from the master cylinder into the wheel cylinder, which in turn pushes the brake shoes into contact with the machined surface on the inside of the drum.

When the brake shoes wear a little more, the adjuster can advance again, so it always keeps the shoes close to the drum.

# When the drums are heated by hard braking, the diameter of the drum increases slightly due to thermal expansion, this means the brakes shoes have to move farther and the brake pedal has to be depressed further.

When traveling downhill some vehicles can use their engines to brake.

When the brake pedal of a modern vehicle with hydraulic brakes is pushed, ultimately a piston pushes the brake pad against the brake disc which slows the wheel down.

When the engineer ( driver ) applies the brake by operating the locomotive brake valve, the train line vents to atmosphere at a controlled rate, reducing the train line pressure and in turn triggering the triple valve on each car to feed air into its brake cylinder.

When the engineer releases the brake, the locomotive brake valve portal to atmosphere is closed, allowing the train line to be recharged by the compressor of the locomotive.

When a ski boot is put in the ski binding, the brake pivots under the downward pressure and runs parallel with the ski allowing free movement.

When he handed it back and I had hold of it safely, Pops was looking toward me and I said `` Now '', to Charlie and he swung the short length of lead pipe he'd meanwhile taken from his pocket, once.

When a fluid is flowing through a closed channel such as a pipe or between two flat plates, either of two types of flow may occur depending on the velocity of the fluid: laminar flow or turbulent flow.

When he lights the pipe, the blast knocks him unconscious, blackens his skin and burns away all his hair.

When the measured pressure is rapidly pulsing, such as when the gauge is near a reciprocating pump, an orifice restriction in the connecting pipe is frequently used to avoid unnecessary wear on the gears and provide an average reading ; when the whole gauge is subject to mechanical vibration, the entire case including the pointer and indicator card can be filled with an oil or glycerin.

When a pipe ( left ) is filled with hair ( right ), it takes a larger pressure to achieve the same flow of water.

When a resonant system such as a blown pipe or plucked string is excited, a number of overtones may be produced along with the fundamental tone.

When a pipe ( left ) is filled with hair ( right ), it takes a larger pressure to achieve the same flow of water.

When she visited the Earth, she gave the Dakota Indians ( Sioux ) a pipe as a symbol of peace.

When recording, the choir is usually accompanied by the Orchestra at Temple Square, the Tabernacle's famous pipe organ, or both.

When the city abandoned the non-pressurized zanja system for a pressurized pipe system, these smaller, shallow reservoirs located at low points no longer provided much benefit.

When pressure is applied to the toothpaste tube, the main material squeezes down the thin pipe to the nozzle.

When a key is depressed, the key action admits wind into a pipe.

When the organist depresses a key, the corresponding tracker moves, allowing wind to enter the pipe.

When marijuana is smoked, the THC behind the hot spot is vaporized as the hot air from the burn is drawn through the joint or pipe bowl to the unburned material.

When he declines, they say, " A pipe, then?

When a valve on the pipe was opened, the vacuum in the condenser would, in turn, evacuate that part of the cylinder below the piston.

When done, the descent of the magnet is observably slower than when dropped outside the pipe ..

When used in agricultural irrigation, the singular form " pipe " is often used as a plural.

When using a horn mouthpiece, an adapter is commonly used so that it fits in the lead pipe of the mellophone.

When a flammable mixture is present in the engine, it will detonate, sending a shock wave down the tail pipe and creating suction at the intake end of the engine, sucking in more fuel / air, and creates another explosion.

When harmony is written within the pipe section, it is usually a two-part harmony, and is usually scored in a 2: 1 ratio ( with two thirds of the players on the melody and one third of the players on the harmony part ).

When air is admitted to the train pipe, the air pressure acts against pistons in cylinders in each vehicle.

When a locomotive is coupled to the vehicles, the driver moves the brake control to the " release " position and air is exhausted from the train pipe, creating a partial vacuum.

When the two are threatened, the chimney sweep gallantly conducts his love safely to the rooftop through the stove pipe.
