Solution

1. Preparation

Tools Required: Brake fluid, funnel, OBD-II scanner, socket set, brake cleaner, torque wrench.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and goggles.

2. Check and Refill Brake Fluid

Sub-steps:
1. Locate the brake fluid reservoir under the hood.
2. Clean the reservoir cap with a cloth to prevent contamination.
3. Open the cap and check the fluid level; it should be between the "MIN" and "MAX" marks.
4. If low, add the appropriate type of brake fluid (usually DOT 3 or DOT 4).
5. Close the cap securely after refilling.

3. Inspect for Leaks

Sub-steps:
1. Visually check brake lines, calipers, and wheel cylinders for any signs of fluid leakage.
2. If leaks are found, identify the source and proceed to replace the damaged component.
3. Clean any spilled brake fluid immediately to prevent damage to vehicle surfaces.

4. Replace Worn Brake Components

Sub-steps:
1. If brake pads are worn (less than 3mm thickness), remove the wheel using a socket set.
2. Remove the caliper bolts and take off the caliper.
3. Replace the old brake pads with new ones, ensuring they are properly seated.
4. Inspect and replace rotors if they are below the minimum thickness or have deep grooves.
5. Reassemble the caliper and wheel, tightening bolts to manufacturer's torque specifications.

5. Test the Brake System

Sub-steps:
1. Start the engine and pump the brake pedal a few times to build brake pressure.
2. Check for the brake warning light; if it remains illuminated, further diagnostics may be necessary.
3. Conduct a test drive to ensure brakes are functioning correctly.
