Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Check Brake Fluid Level

Locate the brake fluid reservoir (usually near the back of the engine bay).
Clean the area around the reservoir cap to prevent contamination.
Remove the cap and check the fluid level; it should be between the minimum and maximum marks.
If low, top off with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).

3. Inspect Brake Pads

Use a jack and jack stands to lift the vehicle safely.
Remove the wheel to access the brake caliper and pads.
Inspect the brake pads for thickness; replace if they are worn down to 3 mm or less.
If replacement is needed, remove the caliper and replace pads following manufacturer specifications.

4. Examine Brake Lines and Hoses

Visually inspect all brake lines and hoses for signs of leaks, cracks, or deterioration.
If any damage is found, replace the affected lines or hoses.
Ensure all connections are tight and secure.

5. Check Brake Warning Switch

Locate the brake warning switch, typically found near the brake pedal assembly.
Inspect for proper connection and functionality by testing with a multimeter.
Replace the switch if it is faulty or not functioning correctly.

6. Reassemble and Test

Reinstall the wheel and lower the vehicle back to the ground.
Reconnect the negative battery terminal.
Test the brakes by pressing the pedal and checking for firmness.
Ensure the brake warning light is no longer flashing.
