Solution

1. Preparation

Gather tools and parts needed for inspection and repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Allow the engine to cool before starting work.

2. Inspect and Repair Brake System

Remove the wheel to access brake components.
Check the brake pads for excessive wear; replace if they are below 3mm thickness.
Inspect the brake rotors for scoring or warping; replace if needed.
Clean the calipers and ensure they are not sticking; lubricate moving parts.
Reassemble the wheel and ensure lug nuts are torqued to the manufacturer’s specifications.

3. Check Engine Components

If oil is found to be burning, replace the engine oil and filter.
- Drain old oil using a socket set and oil filter wrench.
- Replace with manufacturer-recommended oil type and fill to the correct level.
Inspect and replace any damaged hoses or belts that could contribute to the burning smell.
Reconnect any loose connections and ensure all components are secure.

4. Final Checks

Recheck fluid levels (coolant, brake fluid, engine oil) and top off as necessary.
Perform a test drive to ensure the burning smell has dissipated and monitor for any unusual noises.
