Describe, using a brake-circuit sketch (and Pascal’s principle), how braking force gets multiplied in a typical automobile, from brake-pedal to brake-pads. Show a schematic to obtain a 36X force multiplier (ie Output force of 360 lb) through a mechanical advantage of brake lever (4X) and remaining through hydraulic force multiplication, for an input force of 10 lb at the master cylinder.

Question

Describe, using a brake-circuit sketch (and Pascal’s principle), how braking force gets multiplied in a typical automobile, from brake-pedal to brake-pads. Show a schematic to obtain a 36X force multiplier (ie Output force of 360 lb) through a mechanical advantage of brake lever (4X) and remaining through hydraulic force multiplication, for an input force of 10 lb at the master cylinder.
