Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery to prevent electrical issues while working.

2. Inspect and Replace Brake Components

Remove Wheel
- Use a jack to lift the vehicle and secure it with jack stands.
- Remove the lug nuts using a socket set and take off the wheel.
Inspect Brake Pads and Rotors
- Check the brake pads for thickness; replace if worn below manufacturer specifications (usually 3mm).
- Inspect rotors for scoring or warping; replace if necessary.
Replace Brake Pads
- Remove the caliper by loosening the caliper bolts with a socket set.
- Slide the caliper off and hang it using a bungee cord (do not let it dangle from the brake line).
- Remove the old brake pads from the caliper bracket.
- Install new brake pads, ensuring they are properly seated.
Reassemble the Brake System
- Reinstall the caliper over the new pads and tighten the caliper bolts to manufacturer torque specifications (typically 25-30 Nm).
- Reattach the wheel and lower the vehicle.

3. Inspect Engine Components

Check for Fluid Leaks
- Examine the engine bay for any signs of oil, coolant, or other fluid leaks that could cause a burnt smell.
- Clean up any spills and replace any damaged components if necessary.
Replace Any Faulty Parts
- If any components are found damaged or leaking, replace them accordingly (e.g., valve cover gaskets, oil pan gaskets).
