Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and secured with wheel chocks.
Wear safety goggles and gloves.

2. Check and Refill Brake Fluid

Locate the master cylinder reservoir.
Remove the cap and check the fluid level.
If low, top up with the recommended brake fluid (DOT 4 or as specified in the owner's manual).

3. Inspect and Replace Damaged Components

Brake Lines:
- Inspect all brake lines for any signs of wear or damage.
- If damaged, use a line wrench to disconnect the affected line and replace it.
Calipers and Wheel Cylinders:
- Remove the wheels to access the brake calipers.
- Check calipers and wheel cylinders for leaks.
- Replace any faulty calipers or wheel cylinders using a socket set to remove bolts.

4. Bleed the Brake System

Start at the wheel farthest from the master cylinder (usually the right rear).
- Connect a bleeder kit or a clear hose to the bleeder valve.
- Open the valve and have an assistant press the brake pedal.
- Close the valve before the pedal is released. Repeat until clear fluid without bubbles is obtained.
- Move to the next wheel (left rear, right front, then left front).

5. Test the Brake System

After bleeding, check the brake pedal feel.
Ensure the fluid level in the reservoir is correct, then replace the cap.
Conduct a test drive at low speeds to ensure brakes are functioning correctly.
