Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the negative battery terminal to avoid electrical hazards.

2. Brake Fluid Inspection and Replacement

Sub-steps:
1. Remove the cap from the master cylinder reservoir.
2. Check the fluid level; if low, top off with manufacturer-recommended brake fluid (DOT 3 or DOT 4).
3. If fluid is contaminated or old, drain the old fluid from the system using a brake bleeder kit.
4. Refill the master cylinder with new brake fluid.

3. Brake Line and Hose Inspection

Sub-steps:
1. Inspect all brake lines and hoses for signs of leaks or corrosion.
2. Replace any damaged or corroded brake lines or hoses with OEM or quality aftermarket parts.
3. Ensure all connections are tight and secure.

4. Brake Pad and Rotor Replacement

Sub-steps:
1. Remove the wheel to access the brake assembly.
2. Remove the caliper bolts and slide the caliper off the rotor.
3. Inspect brake pads; if worn below the minimum thickness, replace them.
4. Check the rotors for wear; if warped or below minimum thickness, replace them.
5. Reassemble the brake components, ensuring all bolts are torqued to manufacturer specifications.

5. Brake Booster and ABS Module Check

Sub-steps:
1. Test the brake booster by pumping the brake pedal with the engine off; the pedal should feel firm.
2. Start the engine; the pedal should drop slightly if the booster is functioning correctly.
3. If the booster is faulty, replace it.
4. If there are ABS-related codes, follow the manufacturer's guidelines to diagnose and repair the ABS module.
