Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to prevent electrical shorts during the repair.

2. Inspect and Replace Brake Fluid

Sub-steps:
1. Open the brake fluid reservoir cap.
2. If the fluid is low, use a clean turkey baster to remove the old fluid.
3. Refill with the appropriate brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).
4. Replace the reservoir cap securely.

3. Check for Leaks

Sub-steps:
1. Visually inspect brake lines, hoses, and connections for signs of fluid leaks.
2. If leaks are found, identify the source and replace the affected components.

4. Brake Pad and Rotor Inspection

Sub-steps:
1. Remove the wheel to gain access to the brake assembly.
2. Inspect brake pads for thickness (minimum thickness should be 3mm).
3. Check rotors for scoring or warping.
4. Replace pads and rotors if they are worn or damaged.

5. Repair or Replace Brake Pedal Switch

Sub-steps:
1. Locate the brake pedal switch, usually positioned above the brake pedal.
2. Test the switch with a multimeter; replace if faulty.
3. Reconnect all wiring and ensure proper operation.

6. Reconnect Battery and Clear Codes

Sub-steps:
1. Reconnect the battery terminal.
2. Use an OBD-II scanner to clear any stored codes.
