3. Refill with the manufacturer's recommended brake fluid (usually DOT 3 or DOT 4).
4. Replace the master cylinder cap securely.
Tools Required: Turkey baster, funnel, clean cloth

3. Check and Replace Brake Pads and Rotors

Sub-steps:
1. Remove the wheel to access the brake components.
2. Inspect brake pads for thickness; if less than 3mm, replace them.
3. Check rotors for grooves or warping; replace if necessary.
4. Remove caliper bolts and slide the caliper off the rotor.
5. Replace brake pads and reassemble the caliper.
6. Reinstall the wheel and torque the lug nuts to the manufacturer's specifications.
Tools Required: Socket set, torque wrench, brake cleaner
Safety Warnings: Ensure the car is securely lifted and supported on jack stands.

4. Brake Booster and Master Cylinder Inspection

Sub-steps:
1. Locate the brake booster and check for any signs of vacuum leaks.
2. Perform a vacuum test on the brake booster using a hand-held vacuum pump.
3. If the booster is faulty, remove it and replace it with a new unit.
4. Remove the master cylinder from the brake booster and inspect for leaks; replace if needed.
Tools Required: Vacuum pump, socket set
