Solution

1. Preparation

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

2. Inspect and Refill Brake Fluid

Sub-steps:
1. Open the hood and locate the brake fluid reservoir.
2. Check the fluid level; if low, add the recommended brake fluid (DOT 4 or as specified in the owner's manual).
3. Inspect for any signs of contamination or discoloration in the fluid.

3. Locate and Repair Leaks

Sub-steps:
1. Visually inspect all brake lines, hoses, and connections for any signs of leakage.
2. If a leak is found, replace the damaged line or hose as necessary.
3. Tighten any loose fittings and ensure all connections are secure.

4. Bleed Brake Lines

Sub-steps:
1. Begin at the brake furthest from the master cylinder (usually the rear passenger side).
2. Attach a clear hose to the bleeder valve and submerge it in a container with brake fluid.
3. Have an assistant pump the brake pedal several times and hold it down.
4. Open the bleeder valve to let air and fluid escape, then close it before your assistant releases the brake.
5. Repeat this process on each brake caliper in the following order: rear passenger, rear driver, front passenger, front driver.

5. Test the Master Cylinder

Sub-steps:
1. Inspect the master cylinder for any signs of external leakage.
2. If leaks are found, replace the master cylinder.
3. If no leaks are present, check the internal seals by applying consistent pressure on the brake pedal; it should remain firm. If it sinks, replacement is needed.
