Chapter 50, Problem 9RQ
Textbook Problem

Explain how vacuum is used to provide a power assist.

Expert Solution
To determine

The use of vacuum in power assists braking system.

Explanation of Solution

In automobiles mainly two types of power-assisted brake mechanism are used. They are:

1. Vaccum assisted:

This type of system uses engine vaccum or generated by some external parts to apply the brakes. These are mainly used in cars.

2. Hydraulic assisted:

This system uses hydraulic pressure developed by the power steering pump to apply the brakes. They are used in heavy trucks and turbocharged vehicles.

Vacuum assisted:

In vacuum assisted power braking, the system generates energy by opposing the engine vacuum to atmospheric pressure. The braking function is assisted by piston and cylinder, a diaphragm and bellow pins...
