Solution

1. Preparation

Tools Required: Socket set, screwdrivers, multimeter, brake cleaner, rags
Safety Warnings: Ensure the vehicle is on a flat surface and the ignition is off.

2. Check Brake Fluid Level

Open the hood and locate the master cylinder reservoir.
Inspect the brake fluid level; if low, fill it with the manufacturer's recommended brake fluid (usually DOT 3 or DOT 4).
Check for leaks around the reservoir and lines.

3. Inspect Brake Pedal Switch

Locate the brake pedal switch, usually found above the brake pedal arm.
Disconnect the electrical connector from the switch.
Using a multimeter, check for continuity when the pedal is pressed. Replace the switch if it is faulty or misadjusted.

4. Examine Brake Components

Remove the wheel to access the brake components.
Inspect brake pads and rotors for wear; replace if they are below the manufacturer's minimum thickness.
Check for any visible leaks from the calipers or brake lines.

5. Test for Fluid Leaks

Clean any spilled brake fluid with brake cleaner.
If leaks are found, replace the damaged brake lines or calipers.
Refill the brake fluid reservoir and bleed the brakes if necessary.
