Solution

1. Preparation

Tools Required: Safety goggles, gloves, flashlight, socket set, torque wrench.
Ensure the vehicle is parked on a level surface and the engine is off. Allow the engine to cool before starting work.

2. Inspect and Replace Brake Components

Sub-steps:
1. Remove the wheel corresponding to the brake system suspected of causing the smell (front or rear).
2. Inspect the brake pads and rotors for wear. Replace pads if they are less than 3mm thick or show signs of burning.
3. If the rotors are scored or warped, replace them as well. Use a torque wrench to tighten the new pads and rotors to manufacturer specifications.

3. Check and Replace Fluid Leaks

Sub-steps:
1. Inspect all fluid reservoirs (engine oil, transmission fluid, brake fluid) for leaks or low levels.
2. If low, top off with the appropriate fluid type as per the owner's manual. If leaking, replace the necessary gaskets or seals.

4. Inspect Belts and Hoses

Sub-steps:
1. Visually inspect serpentine belts and hoses for cracks or signs of wear.
2. If any damage is found, replace the affected components. Ensure proper routing and tension according to manufacturer specifications.

5. Check Cooling System

Sub-steps:
1. Inspect the radiator for leaks and ensure all hoses are connected and in good condition.
2. Check coolant levels and top off with the recommended coolant if low.
3. If the cooling system is not functioning properly, consider flushing the system and replacing the thermostat if necessary.
