Solution

1. Preparation

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

2. Check Brake Fluid

Remove the cap from the brake fluid reservoir.
Inspect the fluid level; it should be between the "MIN" and "MAX" marks.
If low, top off with the manufacturer's recommended brake fluid (DOT 3 or DOT 4).
Check for any signs of contamination in the fluid.

3. Inspect Brake Lines and Components

Visually inspect all brake lines, hoses, and connections for leaks or damage.
Tighten any loose connections and replace any damaged brake lines.
Check the condition of the brake pads and rotors; replace if worn out.

4. Bleed the Brake System

Start with the wheel farthest from the master cylinder (usually the passenger rear).
Use a brake bleeder kit or a helper to press the brake pedal while you open the bleeder valve on the brake caliper.
Allow old fluid and air to escape until new fluid flows out; close the valve before releasing the pedal.
Repeat this process for each wheel in the correct order (passenger rear, driver rear, passenger front, driver front).

5. Test Brake Booster and Master Cylinder

Inspect the brake booster for vacuum leaks (listen for hissing sounds).
Remove and bench-test the master cylinder if no leaks are found; replace if faulty.
