Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface, and set the parking brake.
Place wheel chocks behind the rear tires for safety.

2. Locate the Leak

Sub-steps:
- Start by checking the brake fluid reservoir; if low, refill with the appropriate brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).
- Inspect the areas around the master cylinder, brake lines, calipers, and brake hoses for signs of leaking fluid.

3. Repair or Replace Affected Components

Sub-steps:
- If the leak is found at the brake lines, replace the damaged section of the line. Use a brake line wrench to disconnect and reconnect fittings. Ensure all connections are tight and free of leaks.
- For leaking calipers, remove the caliper bolts using a socket set, replace the caliper or reseal if possible, and reattach the caliper. Torque bolts to the manufacturer’s specifications.
- If the master cylinder is leaking, remove it by disconnecting the brake lines and mounting bolts. Replace it with a new unit and refill the system with brake fluid. Bleed the brake system to remove air.

4. Bleed the Brake System

Sub-steps:
- Using a brake bleeder kit, start from the farthest wheel from the master cylinder (usually the passenger side rear) and work towards the closest (driver side front).
- Ensure the brake fluid reservoir is kept topped up during bleeding. Open the bleeder valve, pump the brake pedal, and close the valve to remove air until fluid flows without bubbles.
- Repeat this process for all four wheels until the brake pedal feels firm.
