Vibration when applying brakes is most likely warped rotors. Another cause could be loose caliper bolts.
yes, but only when the brakes are applied.
no
Your brake rotors are warped and need replaced/resurfaced.
Could be that the rotors are "out of round" and need either to be resurfaced or replaced
Friction
yes
In general, warped brake rotors will cause a vehicle to shake when the brakes are applied. If the problem is severe, it will also have some impact on the ability of the driver to control the car when braking. If a car shudders or shakes when the brakes are applied but is otherwise smooth when driven, the brakes are a most logical cause. Use the link to the related question below to help you decide what to do if you suspect a warped brake rotor.
vacuum leak 65 power brakes run off a vacuum, when you apply your brakes you stop the air leak. 65;
A car slowing down when the brakes are applied.
The friction caused by the brakes causes the car to decelerate. This negative acceleration, in turn, causes a force to be applied to all those in the car. This is the lurch you feel.
When car brakes are applied, they create friction between the brake pads and the wheels. This friction slows down the wheels, reducing the car's speed.
When the brakes are applied, the car's kinetic energy is converted to heat by friction between the brake pad and the brake disk.
