Wear appropriate safety gear including gloves and safety glasses.

2. Identify and Isolate the Leak

Tools Required: Brake cleaner, clean rags
Clean the affected area with brake cleaner to remove old fluid residue.
Inspect the cleaned area closely to identify the source of the leak.

3. Replace Damaged Components

A. Brake Lines

Tools Required: Wrench set, line cutter, flare tool
If a brake line is damaged:
1. Use a line cutter to remove the damaged section.
2. Measure and cut a new line to the correct length.
3. Flare the ends of the new line.
4. Attach the new line using appropriate fittings and torque to manufacturer's specifications.

B. Brake Calipers

Tools Required: Socket set, torque wrench
If a caliper is leaking:
1. Remove the wheel and caliper mounting bolts.
2. Take off the caliper and replace it with a new or remanufactured unit.
3. Reinstall the caliper and torque bolts to manufacturer's specifications.

C. Master Cylinder

Tools Required: Wrench set, torque wrench
If the master cylinder is leaking:
1. Disconnect the brake lines from the master cylinder.
