Solution

1. Preparation

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

2. Check and Refill Brake Fluid

Locate the brake fluid reservoir.
If the fluid level is low, top it off using the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
Inspect for any signs of contamination in the fluid.

3. Inspect and Repair Brake Lines

Raise the vehicle using a jack and secure with jack stands.
Visually inspect all brake lines for corrosion, cracks, or leaks.
If leaks are found, replace the affected sections of the brake line using a proper brake line repair kit.

4. Examine Brake Components

Remove the wheel to access the brake assembly.
Inspect brake pads for wear; replace if they are worn down to less than 3mm.
Check the brake rotors for warping or scoring; machine or replace as necessary.

5. Test the Brake Booster

With the engine off, pump the brake pedal several times to release any vacuum.
Start the engine and press the brake pedal; it should feel firmer. If not, the brake booster may be faulty and should be replaced.

6. Bleed the Brake System

Use a brake bleeder kit to remove any air in the brake lines.
Start with the wheel farthest from the master cylinder and work your way to the nearest.
Ensure the brake fluid reservoir remains full during the bleeding process.
