Diagnostic Steps

2
Open the hood and locate the brake fluid reservoir.
3
Assess the fluid level against the markings on the side of the reservoir.

Solution

1. Preparation

Gather necessary tools: flashlight (if needed for visibility).
Ensure personal safety gear is worn (gloves and safety glasses).

2. Locate the Brake Fluid Reservoir

Open the hood using the release lever inside the vehicle.
Use the hood prop to secure the hood in an open position.
Find the brake fluid reservoir, which is typically located near the back of the engine bay on the driver's side.

3. Check Brake Fluid Level

Inspect the reservoir from the side to see the fluid level. The reservoir has "MIN" and "MAX" markings.
If the fluid level is below the "MIN" line, it needs to be topped up.
If the fluid is dark or contaminated, it should be replaced.

4. Add Brake Fluid (if necessary)

Remove the cap of the brake fluid reservoir.
Use only the recommended brake fluid type (usually DOT 3 or DOT 4).
Add fluid until it reaches the "MAX" line, being careful not to overfill.
Replace the cap securely.

5. Final Checks

Inspect for any leaks around the reservoir and brake lines after topping up.
Close the hood securely.
