(1)there is a leak in the system, (2)fluid reservoir is low, (3)air in the lines.
No, that is certainly not normal. It means that there is an air bubble in the hydraulic brake lines or if there are drum brakes, they aren't adjusted right. ==Additional comment == !!! Get that fixed ASAP, it's VERY dangerous.
Kinetic friction is the force that stops a train when the brakes are applied
have your brakes checked

slowly push it along then pull the brakes, if it stops, THE BRAKES WORK!!! if it keeps going, THE BRAKES DON'T WORK!!! IT'S ROCKET SCIENCE!!!
friction by applying the brakes? When you apply the brakes, there are pads on either side of the metal part of the wheel, they squeeze together tighter and tighter until the wheel stops turning, which stops the motion of the bike.
Keep the car straight. Ease of gas, do not apply brakes. Let the car slow down until it is almost stopped . Right before your car stops pull of the road and apply brakes.
hold - A tactic by which a senator asks to be informed before a particular bill is brought to the floor. This stops the bill from coming to the floor until the hold is removed
The brakes apply force to the wheel, causing friction which stops it.
