When a driver presses the brake pedal, mechanical energy from the driver's foot is transferred to the brake system through a series of linkages and hydraulic components. This action compresses brake fluid within the brake lines, creating hydraulic pressure that activates the brake calipers. The calipers then clamp down on the brake rotors, converting kinetic energy from the moving vehicle into thermal energy through friction, effectively slowing down or stopping the vehicle.
A little bit of chemical energy from the food that the rider has eaten gets used to pull on the brake lever, the rest is friction. When you pull the brake then a sort of bar comes down onto the wheel. This uses the opposite force of friction to slow you down.
In a hyrid car, when you brake the energy that is used is transferred back into electricity instead of totally lost as heat energy.
The surfaces of a brake pad.
Assuming the vehicle stops because the brakes are applied - it would be kinetic energy transferred to heat via friction with the brake pads and brake shoes (mostly). Some would be kinetic energy transformed to heat via friction with the wheels on the road and the turning parts of the axle, transmission, etc.
You could be pressing the brake pedal too hard. Another reason why it may jerk is because the pull brake is engaged.
When the driver brakes, friction between the brake disks and pads produces heat through the conversion of kinetic energy to internal energy. This heat generated helps slow down the car by reducing its kinetic energy. The higher the friction force between the brake components, the more kinetic energy is converted to heat.
Probably brake pads.
Hovering your foot over the brake without actually pressing on the brake
Basically, a brake assist system monitors the driver?s use of the brake pedal, automatically sensing an attempt to stop the car as a result of panic. It then generates very high braking power, even when the driver is only pressing lightly on the brake pedal. When this is used together with anti-lock braking systems, it results in faster and safer braking. Source: http://www.brakeassist.com

Master cylinder, is the brake fluid reservoir. It is mounted on the brake booster, on the firewall, driver's side.Master cylinder, is the brake fluid reservoir. It is mounted on the brake booster, on the firewall, driver's side.
do your brake lights work wen pressing brake . if not its the brake pedal sensor
