Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the battery to prevent electrical shorts.

2. Check Brake Fluid Level

Locate the brake fluid reservoir, usually found near the driver's side of the engine bay.
If the fluid is low, fill it with the recommended brake fluid (DOT 3 or DOT 4, depending on the model).
Reconnect the battery and check if the warning light turns off.

3. Inspect and Replace Brake Pads

Tools Required: Socket set, brake pad spreader, torque wrench.
Remove the wheel to access the brake assembly.
Use the socket set to remove the caliper bolts and lift the caliper off the rotor.
Inspect the brake pads for wear; if they are below the recommended thickness (usually 3mm), replace them.
Install new brake pads and reassemble the caliper, tightening bolts to the manufacturer's torque specifications.

4. Inspect Brake Lines and Components

Visually check all brake lines for leaks, cracks, or corrosion.
If any leaks are found, replace the affected brake line.
Inspect the master cylinder for signs of leakage; if leaking, it must be replaced.
Reconnect any disconnected components and ensure they are secured.
