Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, brake fluid, torque wrench.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative terminal of the battery to avoid electrical issues.

2. Address Brake Fluid Issues

If the brake fluid level is low:
- Locate the brake fluid reservoir and remove the cap.
- Add the appropriate type of brake fluid (e.g., DOT 3 or DOT 4) until it reaches the full mark.
- Reinstall the reservoir cap securely.

3. Replace Worn Brake Pads/Discs

If brake pads or discs are worn:
- Remove the wheel using a socket set.
- Remove the caliper bolts and carefully slide the caliper off the rotor.
  - Safety Warning: Do not let the caliper hang by the brake line; support it with a wire or bungee cord.
- Remove the old brake pads and inspect the discs for scoring or warping.
- Install new brake pads and reattach the caliper, ensuring bolts are torqued to manufacturer specifications.
- Replace the wheel and torque the lug nuts in a star pattern.

4. Check and Replace Brake Pedal Switch

If the brake pedal switch is faulty:
- Locate the brake pedal switch, typically found above the brake pedal.
- Disconnect the wiring harness from the switch.
- Remove the switch from its bracket.
- Install the new brake pedal switch and reconnect the wiring harness.

5. Clear Error Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any stored brake error codes.
Start the vehicle and check if the warning lights remain illuminated.
