4.2.7Explore:Driving Safety and Friction CoefficientsExplorationPhysics Sem 1Points Possible:25In this practice, you will apply what you have learned in the lesson. Answer the questions below. Submit this to your teacher when you are done.1. Use this article to answer questions about the braking systems used in cars. (9 points)How the Braking System Worksa. How do brake hydraulics work?. (3 point)Brake Hydraulics use a fluid-filled master and slave cylinders connected by pipes. The fluid flows through pipes when there is pressure put on the brakes. It fills slave cylinders, which forcespistons out. Fluid pressure is distributed evenly throughout the system. The exerted force gets multiplied by the brakes because of the arrangement. b. Describe disc brakes and the importance of friction in their use. (2 points)Disc brakes have disks that turn with the wheel, because hydraulic pistons worked by pressure press on friction pads, clamping on disks from each side in order to stop it.
c. Describe drum brakes and the importance of friction in their use. (2 points)
