Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Wear safety gloves and goggles.

2. Identify the Leak Source

Sub-steps:
1. Remove the wheel corresponding to the suspected leak for better access (if applicable).
2. Clean the area around the suspected leak with brake cleaner to see the source of the fluid.
3. Use a flashlight to inspect for cracks or damaged fittings.

3. Repair or Replace Damaged Components

Sub-steps:
1. If a brake line is damaged, use a pipe cutter to remove the damaged section and replace it with a new line.
2. For calipers or wheel cylinders with leaks, remove bolts and disconnect the hydraulic line, then replace the component.
3. If the master cylinder is faulty, disconnect the brake lines, remove mounting bolts, and replace with a new master cylinder.

4. Refill Brake Fluid

Sub-steps:
1. Use the appropriate brake fluid type specified in the owner’s manual (typically DOT 3 or DOT 4).
2. Fill the brake fluid reservoir to the recommended level.

5. Bleed the Brake System

Sub-steps:
1. Start at the wheel furthest from the master cylinder and work towards the closest.
2. Use a brake bleeder kit or have an assistant pump the brake pedal while you open the bleeder valve to allow air and old fluid to escape.
3. Repeat the process until clear fluid without bubbles flows from the bleeder valve.

6. Reassemble and Test

Sub-steps:
1. Reattach any removed components and ensure all connections are tight.
2. Reinstall the wheel and lower the vehicle.
3. Test the brake pedal feel and inspect for any leaks before driving.
