Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Brake Fluid

Sub-steps:
1. Open the master cylinder reservoir cap.
2. Remove any old fluid using a turkey baster or similar tool.
3. Refill with fresh brake fluid as per manufacturer specifications (DOT 3 or DOT 4).
4. Replace the reservoir cap securely.

3. Check for Leaks

Sub-steps:
1. Visually inspect brake lines, calipers, and wheel cylinders for signs of leaks.
2. If leaks are found, replace damaged lines or seals.
3. Tighten any loose connections.

4. Inspect Brake Components

Sub-steps:
1. Remove the wheel to access brake components.
2. Check the thickness of the brake pads; replace if worn below the minimum thickness.
3. Inspect the rotors for wear or warping; replace if necessary.
4. Reinstall the wheel and torque to manufacturer specifications.

5. Test Brake Booster

Sub-steps:
1. Start the engine and press the brake pedal several times to deplete vacuum.
2. Press the pedal again; if it feels hard, the booster may be faulty and should be replaced.
3. If necessary, remove and replace the brake booster following manufacturer guidelines.
