Bleed the brake system after installation to remove air bubbles.

If the leak is from the brake caliper:

Tools Required: Socket set, torque wrench
Remove the caliper by undoing the mounting bolts.
Replace the caliper with a new one, ensuring to use new seals if necessary.
Reinstall the caliper and torque bolts to manufacturer specifications.

If the leak is from the master cylinder:

Tools Required: Socket set, brake fluid
Remove the master cylinder from its mounting.
Replace with a new master cylinder and ensure all connections are tight.
Refill the brake fluid reservoir and bleed the brake lines.

4. Final Assembly

Reinstall the wheel and lower the vehicle.
