itz 4 science hmewrk....i dnt hav a clue!!!!!!!!!!! and.... how does it wrk??
while the brake pedal is pressed, leverage multiplies the stress utilized from the pedal to a vacuum booster. The booster multiplies the stress back and acts upon a piston interior the grasp cylinder. As stress is utilized to this piston, stress interior the hydraulic equipment will develop, forcing fluid interior the direction of the strains to the slave cylinders. the two maximum trouble-free preparations of slave cylinders are a pair of antagonistic pistons that are compelled aside by using the fluid stress (drum brake), and a single piston that's compelled out of its housing (disc brake). The slave cylinder pistons then practice stress to the brake linings (many times noted as shoes for drum brakes and pads for disc brakes). The stress utilized to the linings lead them to be pushed against the drums and rotors. The friction between the linings and drum/rotor motives a braking torque to be generated, slowing the automobile.
Braking requires mechanical "pushing" on a disc brake puck against the rotor. This friction is what slows the car down, bringing it to a stop. In order to get the "push" to the puck (actually eight of them- two on each wheel), you have to get the force from the brake pedal to the puck. Because hydraulic fluid is liquid, it's very flexible and doesn't compress. So if the brake lines bend and turn, to get to the puck(s), that's fine. Some systems have vacuum assist, in which a small amount of pressure at the pedal becomes a greater pressure at the puck. The topic is pretty large, but you get the general ideal. good luck !!
