1. Preparation

Gather required tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical issues.

2. Inspect and Replace Brake Fluid

Sub-steps:
- Open the brake fluid reservoir cap and check the fluid level.
- If low, top off with the manufacturer-recommended brake fluid (usually DOT 3 or DOT 4).
- Check for any signs of contamination.
- If the fluid appears dirty, flush the brake system.

3. Inspect and Replace Brake Pads and Rotors

Sub-steps:
- Remove the wheel to access the brake assembly.
- Inspect the brake pads for thickness; replace if below 3mm.
- Measure the rotor thickness with a caliper; replace if below the minimum specification.
- Replace pads and rotors as necessary, ensuring proper alignment.

4. Inspect Brake Lines and Hoses

Sub-steps:
- Visually inspect all brake lines and hoses for cracks or leaks.
- Replace any damaged or worn hoses with OEM parts.
- Ensure all connections are tight and free from leaks.

5. Test Brake Warning Switch

Sub-steps:
- Locate the brake warning switch, usually at the brake fluid reservoir or near the brake pedal.
- Test the switch with a multimeter for continuity when the pedal is depressed.
- Replace the switch if it is faulty.
