Solution

1. Preparation

Gather necessary tools and parts.
Safely park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on the electrical components.

2. Check and Top Off Brake Fluid

Tools Required: Brake fluid, funnel
Sub-steps:
1. Locate the brake fluid reservoir (usually near the driver's side).
2. Remove the cap and check the fluid level against the "MIN" and "MAX" markings.
3. If low, add the appropriate type of brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).
4. Replace the cap securely.

3. Inspect Brake Components

Tools Required: Jack and jack stands, lug wrench, flashlight
Sub-steps:
1. Lift the vehicle using a jack and support with jack stands.
2. Remove the wheels using a lug wrench.
3. Inspect brake pads for thickness; replace if less than 3mm.
4. Check rotors for scoring or excessive wear; machine or replace if necessary.
5. Examine brake lines for any signs of wear, cracks, or leaks.

4. Replace Faulty Components

Tools Required: Socket set, torque wrench, brake pad replacement kit (if needed)
Sub-steps:
1. If brake pads are worn, remove the caliper bolts and slide off the caliper.
2. Replace the brake pads with new ones, ensuring they are properly aligned.
3. If rotors are damaged, remove them and replace with new rotors, torquing to manufacturer's specifications.
4. Reassemble the brake caliper and wheels, ensuring all fasteners are securely tightened.

5. Final Checks

Tools Required: Brake fluid, multimeter (for electrical issues)
Sub-steps:
1. Refill the brake fluid reservoir if necessary.
2. Reconnect the battery.
3. Start the vehicle and pump the brake pedal to ensure proper pressure.
4. Check for any leaks and ensure the warning light is no longer illuminated.
