Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secure with jack stands.
Wear safety goggles and gloves.

2. Inspect Brake Fluid Level

Open the hood and locate the brake master cylinder.
Check the brake fluid level; if low, top up with manufacturer-recommended brake fluid (usually DOT 3 or DOT 4).
Close the cap securely.

3. Check for Leaks

Visually inspect brake lines for any signs of fluid leaks.
Examine the calipers and wheel cylinders for leaks.
If leaks are found, replace the damaged components.

4. Bleed the Brake System

Start at the wheel farthest from the master cylinder (usually the rear passenger side).
Use a brake bleeder kit or a clear hose connected to the bleeder screw on the caliper.
Have an assistant pump the brake pedal several times and hold it down.
Open the bleeder screw to release air and fluid; close the screw before the pedal is released.
Repeat until no air bubbles are present in the fluid.
Move to the next wheel and repeat the process until all wheels are bled.

5. Inspect and Replace Worn Components

Remove the wheel to access the brake assembly.
Check brake pads for thickness; replace if worn below the manufacturer’s specifications.
Inspect rotors for warping or scoring; replace if necessary.
Reassemble the wheel and torque lug nuts to the specified value.
