Solution

1. Preparation

Tools Required: Socket set, brake fluid, rags, jack and jack stands, safety goggles, gloves.
Ensure the vehicle is parked on a level surface and the engine is off.
Allow the vehicle to cool down if it was recently in use.

2. Identify Source of Leak

Sub-steps:
1. Remove the wheel where the leak is suspected (if applicable).
2. Clean the area around the brake components to remove old fluid and debris.
3. Inspect brake lines and connections thoroughly for cracks or damage.
4. Check the master cylinder and brake booster for signs of leakage.

3. Repair or Replace Damaged Components

Sub-steps:
1. If a brake line or hose is damaged, use a line wrench to disconnect it and replace it with a new one.
  - Torque the connections to the manufacturer's specifications.
2. If the master cylinder is leaking, remove it by disconnecting the brake lines and unbolting it from the mounting.
  - Install a new master cylinder and torque bolts to manufacturer's specifications.
3. For leaking brake calipers, replace the caliper or rebuild it with a seal kit if applicable.
4. Add new brake fluid to the reservoir after all repairs are made.

4. Bleed the Brake System

Sub-steps:
1. Start at the wheel farthest from the master cylinder and work towards the closest.
2. Attach a clear hose to the bleeder valve on the brake caliper and submerge the other end in a container of brake fluid.
3. Have an assistant pump the brake pedal, then hold it down while you open the bleeder valve to release air and fluid.
4. Close the bleeder valve before your assistant releases the brake pedal. Repeat until no air bubbles appear in the fluid.
5. Check fluid levels frequently and top off as needed.
