Solution

1. Preparation

Tools Required: Clean rag, funnel, brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).
Ensure the vehicle is on a level surface.
Turn off the ignition and engage the parking brake.

2. Check Brake Fluid Level

Locate the brake fluid reservoir, which is typically found on the driver's side near the back of the engine bay.
Clean the reservoir cap with a clean rag to prevent contamination.
Remove the reservoir cap and visually check the fluid level against the "MIN" and "MAX" markings on the side of the reservoir.

3. Add Brake Fluid

If the fluid is below the "MIN" mark, use a funnel to add the appropriate brake fluid (DOT 3 or DOT 4).
Fill the reservoir until the fluid reaches the "MAX" mark, but do not overfill.
Replace the reservoir cap securely to prevent contamination.

4. Inspect and Test the Braking System

After adding fluid, start the vehicle and pump the brake pedal a few times to circulate the fluid and check for any changes in pedal feel.
Inspect for any visible leaks around the brake lines, calipers, and the reservoir.
