Disconnect the battery to prevent electrical shock or short circuits.

2. Inspect and Replace Brake Components

Sub-steps:
1. Remove the wheel to access the brake assembly.
2. Inspect brake pads for wear – replace if they are less than 3mm thick.
3. Check the brake rotors for warping or excessive wear – replace if necessary.
4. Reassemble the brake components and wheel, tightening lug nuts to the manufacturer's specifications.

3. Check Engine Components

Sub-steps:
1. Remove engine covers if necessary to access critical components.
2. Inspect the engine for oil leaks, particularly around gaskets and seals.
3. Replace any damaged or worn gaskets or seals to prevent leaks.
4. Check for any burnt wiring or damaged connectors, replacing as needed.

4. Address Fluid Issues

Sub-steps:
1. Inspect all fluid levels, including engine oil, transmission fluid, and brake fluid.
2. Top off or replace fluids that are low or contaminated.
3. If any fluid leak is found, repair the source of the leak and replace the affected fluid.
