Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Wear gloves and safety goggles.

2. Check and Refill Brake Fluid

Open the hood and locate the brake master cylinder.
Remove the cap and check the brake fluid level.
If low, add the appropriate brake fluid (DOT 3 or DOT 4 as specified in the owner's manual) to the recommended level.

3. Inspect Brake Lines and Components

Visually inspect all brake lines, calipers, and wheel cylinders for any signs of leaks or damage.
If leaks are found, replace the affected components.

4. Bleed the Brake System

Start at the wheel farthest from the master cylinder (usually the right rear).
Attach a brake bleeder kit or clear hose to the bleeder valve on the brake caliper.
Have an assistant depress the brake pedal while you open the bleeder valve, allowing air and old fluid to escape.
Close the valve before your assistant releases the pedal.
Repeat this process for each wheel in the order: right rear, left rear, right front, left front.
Ensure the brake fluid level remains adequate throughout the bleeding process.

5. Inspect and Replace Brake Pads and Rotors (if necessary)

If brake pads are worn below the manufacturer’s specifications, remove the wheel and caliper.
Replace the brake pads and inspect the rotors for scoring or warping. Replace if necessary.
Reassemble the brake components and ensure everything is torqued to the manufacturer's specifications.
