Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the battery to prevent any electrical issues.

2. Address Fluid Leaks

Step 1: Inspect for any oil leaks by checking the oil pan and gaskets. If found, replace the damaged gasket or seal.
Step 2: Check the transmission fluid and power steering fluid levels; top off or replace as necessary.
Tools Required: Socket set, fluid catch basin.

3. Brake System Inspection
