Does a car's brake system multiply the force of the driver's tap on the brake pedal?

Yes. Most cars have a hydraulic braking system that uses a vacuum servo (or booster).
It is a mechanical device between the brake pedal and the master cylinder piston.
The booster uses the engine's manifold vacuum to amplify the force applied from the brake pedal.

Which of the following statements about a typical hydraulic brake system true?
A hydraulic brake pedal acts as a lever to multiply force
Why were hydraulics put on cars?
Hydraulic power will multiply you. You press down on the brake pedal force and speed of heavy vehicles to easily stop. A hydraulic brake system in your car is simple.
A pulley system can?
Change the direction of force and multiply the force.
Why is it important to check your brake fluid?
Your brake fluid is how the brake system converts mechanical force of your foot on the brake pedal, into hydraulic force that applies your brakes. Without fluid, your hydraulic brakes will not function.
True or false a car's brake system multiplies the force of the driver's tap on the brake pedal?
true!
How does vacuum pump force brake fluid through the lines?
Screw taking special vacuum brake system is in the winding cursed the brake.
How much does a block and tackle pulley system multiply the effort force?
4 (:
A system of pulleys designed to multiply the effort force is called a what?
moveable pulley
What is a system of pulleys designed to multiply the effort force called?
moveable pulley
What is the purpose of the slack adjuster on the air brake system?
It takes up the slack in the brake system as the pad lining and system components ware. The S-cams have bushings that ware out (get egged shaped) creating more clearance, the pads ware do to their function, the clevis pins on the slack adjuster ware. The device rotates the S-cam further to take up that slack. They are also a lever, they add mechanical advantage. Typical slacks are 5.5 and 6.5 from pin center to S-cam center. Multiply the force that a brake chamber rod is exerting by the length of the slack to get applied force. Example, a 30 in brake chamber with 20 psi applied will push with 600 psi of force. Multiply by the lever arm at 5.5 inches gives you 3300 in. pounds of torque. Divide by 12 to get ft. lbs = 275 ft. lbs.
What are a hydraulic system's uses?
An hydraulic systems uses are to multiply the "effort force" or the force that person is applying to the simple machine
What is a self energising brake?
A self energizing brake is one that uses the actual braking drag force to increase the force with which the brake is applied. Before the advent of power brakes, many cars, particularly heavy ones, were equipped with various forms of self energizing brakes in order to reduce the force required on the brake pedal. A simple type is the leading shoe drum break, in which the brake shoe leads it's pivot point. That is, the pivot point is at the trailing end of the brake shoe, considered from the direction of motion of the brake drum. In this design, applying the brake causes the brake shoe to drag against the brake drum, with more force then works to force the shoe against the drum with more force still, thus getting more breaking from the initial application force, multiply it by some factor.
