Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely lifted with jack stands.
Disconnect the battery to prevent electrical issues while working.

2. Inspect and Replace Brake Fluid

Remove the master cylinder cap and visually inspect the brake fluid.
If fluid is low, top it up with manufacturer-recommended brake fluid (DOT 3 or DOT 4 depending on the model).
If fluid is contaminated or old, proceed to flush the brake system.

3. Bleed the Brake System

Attach a brake bleeder kit to the brake caliper or wheel cylinder.
Start with the wheel farthest from the master cylinder (usually the right rear).
Have an assistant pump the brake pedal several times and hold it down.
Open the bleeder valve to release air and old fluid, then close the valve before the pedal is released.
Repeat for all wheels in the correct order (right rear, left rear, right front, left front).
Check fluid levels in the master cylinder during the process; top up as necessary.

4. Inspect and Replace Brake Components

Remove the wheel to access the brake assembly.
Check brake pads for wear; replace if they are below the manufacturer's specifications.
Inspect rotors for warping or scoring; replace if damaged.
Replace any cracked or leaking brake hoses.

5. Reassemble and Test

Reinstall the wheel and lower the vehicle.
Reconnect the battery.
Test the brake pedal for firmness before driving.
Conduct a test drive to ensure brakes engage properly.
