Basic Brake Diagram (Disc brake example)
When you press the brake pedal in your car hydraulic fluids communicate the pressure to the brake pads which press against the brake discs. Friction between the pads and discs slow down your car. If you press down on the brake pedal with a force of 38 N, what is the friction force between one set of brake pads and disc? (Area of master cylinder is 1.7 cm^2, area of brake cylinder is 6.4 cm^2, and the coefficient of friction between the pads and discs is 0.55)
