2. Tighten any loose fittings and replace any damaged hoses or lines.
3. If leaks are identified at calipers or wheel cylinders, replace the affected components.

Tools Required:

Wrench set
Brake line cutter (if needed for replacement)

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

Sub-steps:
1. Remove the brake lines from the master cylinder using a line wrench.
2. Unbolt the master cylinder from the brake booster and remove it.
3. Install the new master cylinder in reverse order of removal, ensuring to torque bolts to manufacturer specifications.
4. Bleed the brake system to remove air.

Tools Required:

Line wrenches
Torque wrench

5. Bleed the Brake System

Sub-steps:
1. Connect a brake bleeder kit to the brake bleeder screw on each caliper, starting with the wheel farthest from the master cylinder.
2. Open the bleeder screw and pump the brake pedal until no air bubbles appear in the fluid.
3. Repeat for each caliper until the brake fluid runs clear.
4. Ensure all bleeder screws are tightened after bleeding.
