Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and turned off.
Wear safety glasses and gloves.

2. Check and Refill Brake Fluid

Open the hood and locate the brake fluid reservoir.
If the fluid level is low, add the recommended brake fluid type (usually DOT 3 or DOT 4).
Check for any leaks around the reservoir and brake lines.

3. 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 the condition of the rotors; replace if they are severely scored or warped.
Reassemble the wheel and lower the vehicle.

4. Address Brake Lines and Leaks

Visually inspect all brake lines for signs of wear, corrosion, or leaks.
If leaks are found, replace the damaged brake lines.
Bleed the brake system to remove any air bubbles after repairs.

5. ABS and Sensor Inspection

Locate the ABS module and inspect for any visible damage or loose connections.
Check ABS wheel speed sensors for dirt or damage, and clean or replace as necessary.
