Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and the parking brake is engaged.
Wear safety gloves and goggles for protection.

2. Check and Refill Brake Fluid

Locate the brake fluid reservoir (usually found near the driver's side).
Remove the cap and check the fluid level; it should be between the 'MIN' and 'MAX' lines.
If low, use the recommended brake fluid type (usually DOT 3 or DOT 4) to refill to the correct level.
Replace the reservoir cap securely.

3. Inspect Brake Pads and Rotors

Lift the vehicle using a jack and support it with jack stands.
Remove the wheel to access the brake assembly.
Inspect the brake pads for thickness (minimum thickness is usually 3mm).
Check the rotors for grooves, cracks, or warping.
Replace pads or rotors if they are worn or damaged.

4. Examine Brake Lines

Inspect the brake lines for any signs of leaks or damage.
Look for corrosion or loose connections.
Replace any damaged lines or fittings.

5. Check Brake Warning Light Circuit

Inspect the fuse related to the brake warning light in the fuse box.
If the fuse is blown, replace it with the same amperage rating.
Use a multimeter to test the continuity of the wiring in the brake warning light circuit.
