Solution

1. Preparation

Tools Required:
- Socket set
- Wrench set
- Brake line flare tool (if needed)
- Catch pan for fluid
Ensure the vehicle is parked on a level surface and the engine is off.
Wear gloves and safety goggles.

2. Identify and Repair Leaks

a. Inspect and Repair Brake Lines

Locate the brake lines under the vehicle.
Sub-steps:
- Visually inspect for any signs of leaks or corrosion.
- Tighten any loose fittings with the appropriate wrench.
- If significant damage is found, replace the affected section of the brake line.
Tools Required: Pipe cutter, flare tool, replacement brake line.

b. Check and Replace Brake Calipers (if necessary)

Remove the wheel to access the brake caliper.
Sub-steps:
- Inspect the caliper for leaks around the piston and seals.
- If leaking, remove the caliper from the mounting bracket.
- Replace the caliper with a new one, ensuring to bleed the brake system afterward.
Tools Required: Caliper tool, brake fluid, bleeding kit.

c. Inspect and Replace the Master Cylinder (if necessary)

Locate the master cylinder atop the brake booster.
Sub-steps:
- Check for signs of fluid leaking from the master cylinder.
- Disconnect brake lines from the master cylinder and remove it from the booster.
- Install a new master cylinder and reconnect all lines, ensuring no cross-threading.
Tools Required: Wrench set, new master cylinder, brake fluid.

3. Refill and Bleed Brake System

After all repairs are made, refill the brake fluid reservoir with the recommended brake fluid (DOT 3 or DOT 4).
Bleed the brake system to remove air.
Sub-steps:
- Start from the wheel farthest from the master cylinder, usually the right rear.
- Open the bleeder valve and pump the brake pedal until fluid flows without bubbles.
- Repeat for each wheel, moving closer to the master cylinder.
