As a safety measure part of the hydraulic booster system includes a(n) __ , which assists in maintaining a reserve of system pressure. a. Power steering pump b. Fluid reservoir c. Accumulator d. Brake reserve light

## Step 1<br />The problem is asking us to identify a component of the hydraulic booster system that assists in maintaining a reserve of system pressure. The options provided are: a power steering pump, a fluid reservoir, an accumulator, and a brake reserve light.<br /><br />## Step 2<br />The power steering pump is responsible for circulating hydraulic fluid throughout the power steering system. While it does play a role in maintaining system pressure, it is not specifically designed to store excess pressure.<br /><br />## Step 3<br />The fluid reservoir is where the hydraulic fluid is stored. While it does hold the fluid, it is not specifically designed to store excess pressure.<br /><br />## Step 4<br />The accumulator is a component of the hydraulic booster system that is specifically designed to store excess pressure. It does this by compressing the hydraulic fluid, which allows it to store a large amount of pressure.<br /><br />## Step 5<br />The brake reserve light is a warning light that indicates when the brake system is not functioning properly. It does not play a role in maintaining system pressure.
