## Step 1The problem presents a situation where a vehicle equipped with 4-wheel disc brakes is not functioning properly. The technician observes that there is no fluid flowing when the brakes are applied, indicating a potential issue with the brake fluid system.## Step 2The brake fluid system is a closed system, meaning that the fluid is not supposed to flow freely when the brakes are applied. If there is no fluid flowing, it suggests that there is a blockage or a leak in the system.## Step 3Given the options, the most logical next step for the technician would be to inspect the brake hose (Option B). The brake hose is a part of the brake fluid system and could potentially be the source of the blockage or leak.## Step 4Inspecting the metering valve (Option A) could be a subsequent step if the brake hose inspection does not reveal any issues. However, the immediate next step should be to inspect the brake hose.## Step 5Options C and D, which suggest replacing the master cylinder and brake pads respectively, are not the immediate next steps. These components are not directly related to the brake fluid flow and would not be the first components to inspect in this situation.
