Tools Required: Jack and jack stands, lug wrench, brake cleaner, new brake pads/rotors if necessary.
Raise the vehicle and remove the wheels.
Inspect brake pads for wear; replace if less than 3mm thick.
Check brake rotors for scoring or overheating; replace if necessary.
Clean the brakes with brake cleaner before reassembly.

4. Examine Exhaust System

Tools Required: Socket set, exhaust clamps if needed.
Inspect the exhaust pipe and muffler for any signs of damage or melting.
Tighten or replace any loose exhaust clamps.
Check for obstructions, like debris, and clear if necessary.

5. Replacement of Serpentine Belt
