Solution

1. Preparation

Gather tools and materials needed for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to prevent electrical issues during repairs.

2. Identify and Repair Leaks

Brake Line Inspection:
- Use a socket set to remove any protective covers or shields.
- Inspect the brake lines visually for rust, corrosion, or physical damage.
- Replace any damaged brake lines with new, OEM-quality lines.
Brake Caliper and Wheel Cylinder Inspection:
- Lift the vehicle using a jack and secure it with jack stands.
- Remove the wheel to access the brake components.
- Check calipers and wheel cylinders for leaks.
- If leaks are found, replace the caliper or wheel cylinder as needed.
Master Cylinder Inspection:
- Locate the master cylinder, typically found near the brake booster.
- Inspect for leaks around the seals and fluid reservoir.
- If leaking, remove the master cylinder by unbolting it from the brake booster.
- Replace with a new master cylinder and ensure proper alignment.

3. Bleed the Brake System

After all repairs, ensure the brake system is bled to remove any air.
- Start at the furthest brake from the master cylinder (usually the rear passenger side).
- Use a brake bleeder tool or have a helper pump the brake pedal while you open and close the bleeder valve.
- Repeat for all four wheels until fluid runs clear without bubbles.

4. Reassemble and Test

Reinstall the wheels and lower the vehicle.
Reconnect the battery.
Test the brake pedal for firmness and responsiveness before driving.
