Solution

1. Preparation

Tools Required: Wrench set, brake fluid tester, bleeder kit, jack and jack stands, torque wrench.
Ensure the vehicle is parked on a flat surface and turn off the ignition.
Disconnect the battery to avoid electrical issues.

2. Inspect and Replace Brake Fluid

Sub-steps:
1. Remove the brake fluid reservoir cap and inspect the fluid. If it's dark or contaminated, proceed with a fluid change.
2. Use a brake fluid tester to check the moisture content in the fluid. If over 3%, replace the fluid.
3. Using the bleeder kit, start at the furthest wheel from the master cylinder. Open the bleeder valve and pump the brake pedal until clean fluid flows out.
4. Repeat for all wheels, ensuring to top off the reservoir as necessary to prevent air from entering the system.
5. Close all bleeder valves securely and recheck fluid level in the reservoir.

3. Inspect Brake Components

Sub-steps:
1. Remove the wheel to access the brake components.
2. Inspect brake pads for thickness; replace if they are below the manufacturer’s specification.
3. Check rotors for warping or overheating signs. Replace if necessary.
4. Ensure calipers are not seizing; clean or replace if they are stuck.

4. Check Brake Lines and Master Cylinder

Sub-steps:
1. Inspect brake lines for any signs of wear, leaks, or damage; replace if found defective.
2. Check the master cylinder for proper operation; ensure it is not leaking or damaged.
3. If any issues are found, replace the master cylinder and bleed the brake system thoroughly again.
