Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and goggles.

2. Inspect and Refill Brake Fluid

Locate the brake fluid reservoir, typically found 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 against the minimum and maximum marks.
If low, add the recommended brake fluid type (DOT 3 or DOT 4) until it reaches the correct level.
Replace the reservoir cap securely.

3. Check for Leaks

Visually inspect the brake lines for cracks, corrosion, or loose fittings.
Examine brake calipers and the master cylinder for signs of fluid leakage.
If leaks are found, replace the damaged components.

4. Brake System Inspection

Remove the wheel to access the brake components if necessary.
Inspect the brake pads for wear; replace if they are below the manufacturer’s specifications.
Check the rotors for warping or damage and replace if needed.

5. System Bleeding (if necessary)

If brake fluid was added or there were leaks, bleed the brake system to remove air.
Start at the wheel farthest from the master cylinder (usually the rear passenger side).
Use a brake bleeder kit or have an assistant pump the brake pedal while you open and close the bleeder valve.
Repeat for each wheel in the correct order (rear passenger, rear driver, front passenger, front driver).
Ensure fluid is at the appropriate level after bleeding.
