Help explaining hydraulic brakes??!!

can someone please explain to me how hydraulic brakes work in an easy way as everyone is confusing me. i need a simple explanation as i am only 14 and need help with homework
thanks a lot everyone :)

its easy sis

pascal principle :" when there is an increase in pressure at any point in a confined fluid, there is an equal increase at every other point in the container"
so

F1/A1=F2/A2

Since you are just second year of your teenage I will like you to do the some experiments, because the theory involves maths well beyond you. But you need to know Pascal's Law. Simply put, if I put pressure on one side of a pipe of 1 kg it will exert a pressure of exactly 10Kg where the pipe is 1/10th diameter. (Minus the losses, don't need to bother at this stage). So with brakes with the pedal we apply some x Kg force (by foot) and it is translated to (x) X (cross section of brake piston diameter/pedal piston diameter). And that is hydraulic brakes.

A piston attached to the brake pedal pushes fluid through pipes and hoses to pistons at the wheels. This moves those pistons, which press against brake pads and press them against the disk brake rotors that spin with the wheels of the car.
