Design Process Technical Research Paper (car breaks) Name: Institution: Date: Design Process Technical Research Paper (car breaks) Braking systems for most, if not all modern cars use hydraulic systems. This system transports the required power to make the braking system frictional surfaces to come into contact with individual wheels of the car.
This foot pressure is necessary in order to actuate brakes. Typically, this can be reduced by making the master cylinder pistons’ surface are smaller compared to the surface area of other piston’s in the wheel cylinders or calipers. The braking systems master cylinder has a fluid reservoir, double cylinder, and piston assembly. These double-type master cylinders are designed to separate front braking systems from rear braking systems hydraulically in instances where there is a leakage. Further, the master cylinder converts mechanical motion originating from the pedal to a hydraulic pressure within the braking lines (Nice, 2010). This hydraulic pressure is then transformed back into mechanical motion at the car wheels either through the drum brakes or the disc brakes. Steel lines are used to ferry the braking fluid to a location on the vehicles frame near the respective wheels. This fluid is then transported to the calipers (disc) or wheel cylinders (drum) using flexible tubes to permit suspension/steering motion (Reuter, 2009). Figure 1: Car brake system Disc and drum brakes For drum brakes, each of its wheel cylinders is made of two pistons, one at each end. These pistons push outward in opposing directions and bring the brake shoe to come into contact with the drum. However, for the disc brakes, the cylinders are included part of the calipers. ...
