Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and engage the parking brake.
Disconnect the battery before working on the braking system for safety.

2. Inspect Brake Fluid Level

Locate the brake fluid reservoir under the hood.
Remove the cap and check the fluid level; it should be between the "MIN" and "MAX" marks.
If low, add the appropriate brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).

3. Check for Leaks

Visually inspect brake lines, calipers, and master cylinder for any signs of fluid leakage.
If leaks are found, identify the source and proceed to replace the damaged components.

4. Inspect Brake Components

Remove the wheel to access the brake assembly.
Inspect brake pads for thickness; replace if worn down to 3mm or less.
Check rotors for scoring or warping; replace if necessary.

5. Bleed the Brakes (if air is present)

Connect a clear hose to the bleeder valve on the brake caliper.
Have an assistant pump the brake pedal several times and hold it down.
Open the bleeder valve to release air and fluid; repeat until no air bubbles are present.
Ensure to top off the brake fluid reservoir periodically during this process.
