3. Remove the caliper or wheel cylinder by unbolting it from the mounting bracket.
4. Install the new caliper or cylinder, ensuring proper alignment.
5. Reconnect the brake line and tighten to the specified torque.

4. Replace Master Cylinder (if leaking)

Sub-steps:
1. Disconnect the battery to ensure safety.
2. Remove the brake fluid reservoir cap and siphon out excess fluid.
3. Disconnect the brake lines from the master cylinder.
