Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Tools Required:
- Brake bleeder kit
- Socket set
- Wrench set
- Brake fluid (DOT 3)
- Floor jack and jack stands

2. Check and Top Off Brake Fluid

Open the hood and locate the brake master cylinder.
Remove the cap and check the brake fluid level.
If low, top off with the appropriate brake fluid (DOT 3).
Replace the cap securely.

3. Inspect for Leaks

Visually inspect all brake lines, wheel cylinders, and the master cylinder for signs of leakage.
If any leaks are found, replace the damaged components.

4. Bleed Brake Lines

Start with the wheel farthest from the master cylinder (usually the right rear).
Attach the brake bleeder kit to the bleeder valve.
Have an assistant pump the brake pedal several times and hold it down.
Open the bleeder valve to release air and fluid, then close it while the pedal is held down.
Repeat until no air bubbles appear in the fluid.
Move to the next wheel and repeat the process (left rear, right front, left front).

5. Inspect and Replace Worn Components (if necessary)

If the brake pads, rotors, or calipers are worn, replace them as needed.
Ensure all components are properly torqued according to manufacturer specifications.
