Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent any electrical issues.

2. Addressing Fluid Leaks

Inspect and Clean:
- Locate the source of the fluid leak.
- Clean the affected area with a degreaser and a cloth.
Replace Leaking Component:
- If oil or coolant is leaking from a gasket, remove the affected component (e.g., valve cover or oil pan).
- Replace the gasket or seal with a new one.
- Reinstall the component and torque to manufacturer specifications.

3. Brake Inspection and Replacement (if applicable)

Remove Wheel:
- Use a jack to lift the vehicle and secure it with jack stands.
- Remove the wheel to access brake components.
Inspect Brake Pads and Rotors:
- Check the thickness of the brake pads; replace if they are below specification (typically 3mm).
- Inspect rotors for warping or scoring; replace if necessary.
Replace Brake Pads:
- Remove the caliper bolts and slide the caliper off.
- Replace with new brake pads and reassemble the caliper.
- Ensure proper brake fluid level before bleeding the brakes.

4. Electrical System Check (if applicable)

Inspect Wiring:
- Look for any signs of burnt wires or connectors.
- Repair or replace damaged wiring as needed.
Testing:
- Reconnect the battery and use a multimeter to check for electrical shorts.
