Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Wear safety gloves and goggles to protect against brake fluid.

2. Check and Top Off Brake Fluid

Locate the brake fluid reservoir (usually near the back of the engine bay).
Remove the cap and inspect the fluid level.
If low, add the appropriate brake fluid type (DOT 3 or DOT 4) until it reaches the "Full" mark.
Replace the cap securely.

3. Inspect Brake Components

Lift the vehicle using a jack and secure it with jack stands.
Remove the wheels to access the brake assembly.
Inspect the brake pads for thickness; replace if they are worn down to 3mm or less.
Check the rotors for grooves, scoring, or excessive wear; consider resurfacing or replacing if damaged.
Examine brake lines for cracks or leaks, and replace any damaged sections.

4. Replace Brake Pads (if necessary)

Remove the caliper bolts using a socket wrench.
Slide the caliper off the rotor and support it without straining the brake line.
Remove the old brake pads and install new ones, ensuring they are correctly aligned.
Reinstall the caliper and torque the bolts to the manufacturer's specifications (typically around 25-35 ft-lbs).

5. Bleed the Brake System (if necessary)

If any brake fluid was added or if components were replaced, bleed the brakes to remove air:
- Start with the wheel furthest from the master cylinder (usually the right rear).
- Use a brake bleeder tool or have an assistant pump the brake pedal.
- Open the bleeder valve on the brake caliper, allowing fluid to escape until no air bubbles appear.
- Close the valve and repeat for each wheel in the correct order (right rear, left rear, right front, left front).

6. Final Checks

Reinstall wheels and lower the vehicle.
Test the brake pedal feel before driving.
Start the engine and check if the brake warning light is still illuminated.
