as part of some science work i have to explain how a hydraulic brake system works

OK with Howdy, good chocolates in Torres + a mug from Zabar's, 4 bucks, it's a small gift from NYC
When the brake pedal is pressed, leverage multiplies the force applied from the pedal to a vacuum booster. The booster multiplies the force again and acts upon a piston in the master cylinder. As force is applied to this piston, pressure in the hydraulic system increases, forcing fluid through the lines to the slave cylinders. The two most common arrangements of slave cylinders are a pair of opposed pistons which are forced apart by the fluid pressure (drum brake), and a single piston which is forced out of its housing (disc brake). The slave cylinder pistons then apply force to the brake linings (generally referred to as shoes for drum brakes and pads for disc brakes). The force applied to the linings cause them to be pushed against the drums and rotors. The friction between the linings and drum/rotor causes a braking torque to be generated, slowing the vehicle.
How Do Hydraulic Brakes Work
easyest way to discribe how it woks isits like a bike hand pump with 4 pipes going to each wheelthe pump handle is the foot brake,just replace the air in the pump with brake fluid,at the end of each pipe theres a smaller hand pump.when you push the big hand pump all other little pumps are forced open[these will be the brake calipers/cylnders.thats about that really.then youve got the brake servo,it uses a vacume from the engine[or a vac pump] to assist in the braking efforthope this helps
