2. Inspect and Replace Brake Lines

Sub-steps:
1. Identify the leaking brake line by following it from the master cylinder to the wheels.
2. Use a pipe wrench to loosen and disconnect the leaking section of the brake line.
3. Remove any mounting clips or brackets securing the line.
4. Install a new brake line, ensuring it is properly routed and secured.
5. Torque fittings to manufacturer's specifications.

3. Replace Brake Calipers or Wheel Cylinders

Sub-steps:
1. Remove the wheel to access the brake components.
2. Disconnect brake lines from the caliper or wheel cylinder using a wrench.
3. Remove the caliper or wheel cylinder from its mounting bracket.
4. Install the new caliper or wheel cylinder, ensuring proper orientation.
5. Reconnect brake lines and torque to manufacturer specifications.

4. Replace Master Cylinder (if necessary)

Sub-steps:
1. Remove the brake fluid reservoir cap and absorb excess fluid.
2. Disconnect brake lines from the master cylinder.
3. Remove the master cylinder mounting bolts and carefully pull it away.
4. Install the new master cylinder and secure it with bolts.
5. Reconnect brake lines and torque to specifications.

5. Bleed the Brake System

Sub-steps:
1. Fill the brake fluid reservoir with new brake fluid (DOT 3 or DOT 4 as specified).
2. Starting from the wheel farthest from the master cylinder, bleed each brake line until no air bubbles appear.
3. Repeat until all lines are bled and make sure the brake pedal feels firm.
