Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Wear safety glasses and gloves.

2. Inspect and Top Off Brake Fluid

Open the hood and locate the brake master cylinder.
Remove the cap and check the brake fluid level.
If low, add the recommended brake fluid (DOT 3 or DOT 4, as specified in the owner’s manual).

3. Check for Leaks

Visually inspect brake lines, hoses, and calipers for any signs of fluid leakage.
If leaks are found, replace the damaged components (lines or calipers).

4. Bleed the Brake System

Locate the brake bleeder valves on each wheel caliper.
Attach a clear hose to the bleeder valve and immerse the other end in a container with brake fluid.
Have an assistant pump the brake pedal several times and hold it down.
Open the bleeder valve to allow air and fluid to escape, then close it before your assistant releases the pedal.
Repeat this process for each wheel until no air bubbles are visible in the fluid.

5. Inspect Brake Components

Remove the wheel to access the brake components.
Check the brake pads for thickness (should be at least 3mm).
Inspect the rotors for scoring or warping; replace if necessary.

6. Reassemble and Test

Reassemble any components removed during inspection.
Ensure all tools are removed from the work area.
Test the brake pedal feel before driving the vehicle.
