Solution

1. Preparation

Ensure the vehicle is parked on a level surface and turn off the engine.
Gather required tools and parts.
Wear safety glasses and gloves during the repair.

2. Check Brake Fluid Levels

Open the hood and locate the brake fluid reservoir.
If fluid is low, fill it with the manufacturer-recommended brake fluid (DOT 3 or DOT 4 depending on specifications).
Check for any visible leaks around the reservoir and lines.

3. Inspect and Replace Brake Pads

Remove the wheel to access the brake components.
Use a caliper tool to compress the caliper piston if pads are being replaced.
Remove the caliper and bracket to access the brake pads.
Inspect the pads for thickness; replace if they are worn down to 3mm or less.
Reinstall new brake pads and torque the caliper bolts to manufacturer specifications.

4. Inspect and Replace Brake Rotors (if needed)

If rotors are damaged or below the minimum thickness, remove them from the hub.
Install new rotors, ensuring they are properly seated.
Torque the rotor retaining screws and install the wheel.

5. Check Master Cylinder and Brake Lines

Inspect the master cylinder for any leaks or damage.
Replace the master cylinder if it shows signs of failure.
Check all brake lines for integrity; replace any damaged or corroded lines.

6. Reset the Brake Warning Light

Use the OBD-II scanner to clear any fault codes and reset the brake warning light.
Perform a test drive to confirm the warning light remains off.
