Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

Tools Required:

Jack and jack stands
Lug wrench
Torque wrench
Brake fluid
Brake cleaner
OBD-II scanner

2. Brake Fluid Inspection and Replacement

Sub-steps:
1. Remove the master cylinder cap and inspect the brake fluid level.
2. If the fluid is low, top it off with the manufacturer's recommended brake fluid (DOT 3 or DOT 4).
3. If the fluid is dirty or contaminated, perform a brake fluid flush.
4. To flush, connect a brake bleeder kit to the brake calipers and pump fresh fluid through until it runs clear.

3. Brake Pad and Rotor Replacement

Sub-steps:
1. Loosen the lug nuts on the front or rear wheels.
2. Jack up the vehicle and secure it with jack stands.
3. Remove the wheel and inspect the brake pads and rotors.
4. If pads are worn down to 3mm or less, replace them. If rotors are scored or warped, replace them as well.
5. Install new brake pads and rotors, ensuring they are aligned properly.
6. Torque the lug nuts to the manufacturer's specifications (typically around 80-100 ft-lbs).

4. Brake Line Inspection and Repair

Sub-steps:
1. Visually inspect the brake lines and hoses for any signs of wear, leaks, or damage.
2. If any issues are found, replace the affected brake line or hose with the appropriate OEM parts.
3. Bleed the brakes after replacing any lines to remove air from the system.

5. Brake Booster and ABS Check

Sub-steps:
1. Inspect the brake booster for any vacuum leaks or damage.
2. If the booster is faulty, replace it with a new unit.
3. Use an OBD-II scanner to check the ABS system for any fault codes and clear them if necessary.
