## Step 1<br />This problem is related to automotive engineering, specifically the braking system. The question is asking which technician is correct in their advice on how to diagnose a problem with a hydro boost brake system that has reduced braking performance.<br /><br />## Step 2<br />Technician A suggests checking the steering system. The steering system is not directly related to the braking system, so this advice is not likely to be helpful in diagnosing the problem.<br /><br />## Step 3<br />Technician B suggests checking the tires. The tires are a crucial part of the braking system. If the tires are worn out or damaged, it can affect the braking performance. Therefore, checking the tires is a sensible step in diagnosing the problem.
