The __ uses hydraulic pressure from the power steering pump to increase the force that acts on the master cylinder. a. Vacuum-assisted power booster b. Hydraulic-assisted power booster c. Individual wheel brake unit d. Electrically assisted power booster

## Step 1<br />The question is asking about a specific component in the braking system of a vehicle. This component uses hydraulic pressure from the power steering pump to increase the force that acts on the master cylinder.<br /><br />## Step 2<br />The options provided are:<br />a. Vacuum-assisted power booster<br />b. Hydraulic-assisted power booster<br />c. Individual wheel brake unit<br />d. Electrically assisted power booster<br /><br />## Step 3<br />The correct answer is option b, the Hydraulic-assisted power booster. This is because it uses hydraulic pressure from the power steering pump to increase the force that acts on the master cylinder.<br /><br />## Step 4<br />The other options do not fit the description given in the question. The Vacuum-assisted power booster uses vacuum pressure, not hydraulic pressure. The Individual wheel brake unit does not use hydraulic pressure from the power steering pump. The Electrically assisted power booster uses electrical power, not hydraulic pressure.
