Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Check and Refill Brake Fluid

Inspect the brake fluid reservoir and check the fluid level.
If low, top off with the manufacturer-recommended brake fluid (DOT 3 or DOT 4 depending on specifications).
Reconnect the battery terminal.

3. Inspect Brake Components

Remove the wheel to access the brake assembly.
Check brake pads for thickness; replace if less than 3mm.
Inspect rotors for grooves or excessive wear; replace if necessary.
Inspect brake lines for any signs of leaks or damage.

4. Replace Worn Components

If brake pads are worn, remove the caliper by unbolting it from the bracket.
- Tools Required: Socket set, torque wrench.
Replace the brake pads with new ones and reassemble the caliper, ensuring it is torqued to manufacturer specifications.
If rotors are worn, remove the caliper and bracket, then unbolt the rotor from the hub and replace it.

5. Check Brake Warning Switch

Locate the brake warning switch, typically found near the brake pedal assembly.
Test the switch for continuity using a multimeter; replace if defective.

6. Final Assembly and Test

Reinstall the wheel and torque it to the manufacturer’s specifications.
Reconnect the battery terminal and clear any fault codes using the OBD-II scanner.
Start the vehicle and check if the brake warning light is still illuminated.
