Question

which of the following applies to brake system hydraulics? a) liquid in a confined space will not compress. b) pressure is transferred equally in all directions. c) hydraulic systems can increase or decrease force or motion. d) all of the above.

Explanation:

• For option A: In brake system hydraulics, the liquid (like brake fluid) in the confined hydraulic lines does not compress, which is essential for transmitting force.
• For option B: Pascal's principle states that pressure in a confined fluid is transmitted equally in all directions, which is how brake hydraulics work to apply force to all brake calipers/pads.
• For option C: Hydraulic systems can use pistons of different sizes to increase or decrease force (or motion), and brake systems can be designed with such principles (e.g., different master and slave cylinder sizes).

Since A, B, and C all apply to brake system hydraulics, the correct option is D.

Answer:

D) All of the above
