5. Install the new brake line and tighten securely (usually 15-20 ft-lbs).
6. Reinstall the wheel.

3. Replace Master Cylinder (if leaking)

Tools Required: Socket set, brake fluid, brake line wrench.
Sub-steps:
1. Disconnect the brake lines from the master cylinder using a brake line wrench.
2. Remove the mounting bolts for the master cylinder.
3. Install the new master cylinder and secure it with bolts (torque to manufacturer specifications).
4. Reconnect the brake lines ensuring tightness to prevent leaks.

4. Replace Brake Calipers (if leaking)

Tools Required: Socket set, brake fluid, caliper tool.
Sub-steps:
1. Remove the wheel and brake pads to access the caliper.
2. Disconnect the brake line from the caliper.
3. Unbolt the caliper from the mounting bracket.
4. Install the new caliper and secure it properly (torque to specifications).
