Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off and parking brake engaged.
Wear safety glasses and gloves.

2. Inspect and Replace Brake Fluid

Sub-steps:
- Open the hood and locate the brake fluid reservoir.
- Remove the cap and check the fluid level; if low, top up with the correct type of brake fluid (DOT 3 or DOT 4 as specified).
- If the fluid appears dark or contaminated, proceed to flush the brake system.
Tools Required: Brake fluid, funnel, rags.

3. Inspect and Replace Brake Pads

Sub-steps:
- Remove the wheel using a lug wrench.
- Use a socket set to remove the caliper bolts and gently slide the caliper off the rotor.
- Inspect the brake pads for thickness; replace if they are less than 3mm.
- To install new pads, compress the caliper piston using a brake caliper tool.
- Reassemble the caliper and wheel, ensuring all fasteners are torqued to specifications.
Tools Required: Lug wrench, socket set, brake caliper tool.

4. Inspect and Replace Rotors (if necessary)

Sub-steps:
- If the rotors are worn or damaged (grooving or excessive rust), remove them by unbolting the rotor from the hub.
- Clean the hub surface and install new rotors, ensuring they align properly.
- Torque the rotor bolts to the specified manufacturer values.
Tools Required: Socket set, torque wrench.

5. Verify Brake Warning Light

After completing repairs, reconnect the battery (if disconnected) and start the vehicle.
Check if the brake warning light is still illuminated. If not, take the vehicle for a test drive to confirm proper brake function.
