Solution

1. Preparation

Gather tools: A clean rag or paper towel for wiping off the reservoir, and if necessary, a funnel for adding fluid.
Ensure the car is on a level surface and the engine is off.

2. Inspect the Brake Fluid Reservoir

Remove the cap of the brake fluid reservoir by turning it counterclockwise.
Clean the area around the cap with a rag to prevent contamination when opening.

3. Check Fluid Level

Observe the fluid level against the MIN and MAX markings on the side of the reservoir.
If the fluid is below the MIN line, additional fluid is required.

4. Add Brake Fluid (if necessary)

Use only the recommended type of brake fluid (usually DOT 3 or DOT 4 as specified in the owner's manual).
If the fluid is low, use a funnel to carefully add brake fluid until it reaches the MAX line.
Avoid overfilling, as this can cause brake fluid to overflow when hot.

5. Replace the Cap

Secure the cap back onto the reservoir by turning it clockwise until it’s tight.
Ensure there is no debris or dirt on the cap or around the reservoir.
