Solution

1. Preparation

Tools Required: Brake fluid, brake bleeder kit, wrench set, and safety gloves.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety gloves and eye protection.

2. Check and Refill Brake Fluid

Open the hood and locate the brake fluid reservoir.
Remove the cap and check the fluid level. If low, add the recommended brake fluid (DOT 3 or DOT 4, depending on the specification).
Inspect for any leaks around the reservoir and refill if necessary.

3. Bleed the Brake Lines

Tools Required: Brake bleeder kit.
Start at the wheel farthest from the master cylinder (typically the right rear).
Attach the bleeder kit to the brake bleeder valve on the caliper.
Have an assistant press the brake pedal slowly while you open the bleeder valve to release air.
Close the valve before the assistant releases the pedal. Repeat until no air bubbles are present.
Move to the next wheel in this order: left rear, right front, left front.
Recheck the fluid level in the reservoir and top off as necessary.

4. Inspect and Replace Master Cylinder (if necessary)

Tools Required: Wrench set and possibly a torque wrench.
If the master cylinder shows signs of leakage or failure, remove it by disconnecting the brake lines and unbolting it from the brake booster.
Install the new master cylinder, ensuring to torque bolts to manufacturer specifications.
Reconnect brake lines and check for tightness.

5. Final Checks

Once repairs are made, re-bleed the brake system to ensure all air has been removed.
Test the brake pedal for firmness before taking the vehicle on the road.
