Solution

1. Preparation

Gather tools and parts necessary for the repair.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery to prevent electrical issues during repair.

2. Identify and Repair the Leak

Brake Line Repair:
- Use a wrench to disconnect the affected brake line at the source of the leak.
- Inspect the line for corrosion or damage; replace if necessary.
- If the line is damaged, cut the line and install a new section with a flare tool.
- Tighten connections securely and check for leaks.
Brake Caliper Replacement:
- Remove the wheel to access the brake caliper.
- Use a socket set to remove the caliper mounting bolts.
- Disconnect the brake line from the caliper using a wrench.
- Install the new caliper and reconnect the brake line, ensuring all connections are tight.
- Reinstall the caliper and wheel.
Master Cylinder Inspection:
- Locate the master cylinder and inspect for leaks around the seals.
- If leaking, remove the master cylinder by disconnecting the brake lines and mounting bolts.
- Replace the master cylinder if damage is found.
- Reinstall the new master cylinder and reconnect brake lines, ensuring they are properly torqued.

3. Refill and Bleed the Brake System

Refill the brake fluid reservoir with the manufacturer-recommended brake fluid type (DOT 3 or DOT 4).
Begin bleeding the brake system starting from the furthest brake caliper to the nearest (right rear, left rear, right front, left front).
Use a brake bleeder kit or have an assistant pump the brake pedal while you open and close the bleeder valves.
