Question

In Jeeps we use
A. Mechanical brakes
B. Hydraulic brakes
C. Air brakes
D. Water breaks

Answer 1

Hint: Use the characteristics of the brakes given in the question. The additional hint is the braking system in Jeep is usually based on the principle of Pascal’s law. Memorize the principle of Pascal’s law and how it is applicable in the braking system.

Complete step by step answer:
A hydraulic brake system uses the brake fluid which usually contains glycol ethers or diethylene glycol, to apply the pressure from the controlling mechanism to the braking system.
The braking fluids move uniformly in all directions whenever the pressure is applied.
The breaking fluids apply the force on a small piston and the resultant pressure is created and transferred to the large piston through the fluid. And at the end result, a high powered braking force is applied on all the wheels.
The braking force produced due to hydraulic pressure is called hydraulic brakes.
Thus, Hydraulic Brakes are used in Jeeps.

So, the correct answer is “Option B”.

Additional Information:
The brake pedal is connected to the master cylinder piston through a piston rod. When the brake is applied, the piston forces into the master cylinder, which increases the pressure of fluid inside the master cylinder and in the entire hydraulic system. Then, instantaneously pressure is conducted to the wheel cylinders on each of the four brakes, where it forces the wheel cylinder pistons outwards. These pistons, in turn, force the brake shoes out against the brake drums, and finally brakes are applied.

Note:
Some advantages of Hydraulic Brakes-
- Simple Construction
- The low wear rate of brake linings
- Increase in Mechanical Advantage
- Equal braking action on all the wheels

Some disadvantages of Hydraulic Brakes-
- Due to leakage of fluid from brake linings, the whole braking system fails
- The presence of Air inside the tubing ruins the whole system.
