Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to prevent electrical issues during repair.

2. Identify Leak Source

Tools Required: Wrench set, flashlight.
Sub-steps:
1. Remove the wheel (if necessary) to gain access to brake components.
2. Use a flashlight to visually inspect the brake lines, hoses, calipers, and master cylinder for any signs of leakage.
3. If a leak is identified, determine if it is from a specific component (e.g., line, caliper, master cylinder).

3. Replace Damaged Components

Tools Required: Wrench set, brake line wrench, fluid catch pan.
Sub-steps:
1. If the brake line is damaged, cut and remove the faulty section, then replace it with new brake line tubing.
2. If the caliper is leaking, remove the caliper bolts, detach the caliper, and replace it with a new one.
3. If the master cylinder is leaking, remove it from its mount, disconnect the brake lines, and replace it with a new master cylinder.

4. Bleed Brake System

Tools Required: Brake bleeder kit, brake fluid.
Sub-steps:
1. Refill the brake fluid reservoir with the manufacturer-recommended fluid.
2. Attach the brake bleeder kit to the furthest brake caliper from the master cylinder.
3. Open the bleeder valve and pump the brake pedal until fluid runs clear with no air bubbles.
4. Repeat for all calipers in order from furthest to closest to the master cylinder.
5. Ensure the brake fluid reservoir does not run dry during the bleeding process.

5. Reassemble and Test

Tools Required: Torque wrench.
Sub-steps:
1. Reassemble any removed components and wheels.
2. Tighten all bolts to the manufacturer's specified torque values.
3. Reconnect the battery and start the vehicle.
4. Press the brake pedal to ensure it feels firm and responsive.
