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

2. Fluid Replacement (if applicable)

Engine Oil Change:
1. Remove the oil drain plug with a socket wrench and drain old oil into a pan.
2. Replace the oil filter using an oil filter wrench.
3. Install the drain plug and torque it to the manufacturer specifications (typically around 20 lb-ft).
4. Fill with new engine oil (5W-20 recommended) and check the level with the dipstick.

3. Brake Inspection and Replacement (if necessary)

Brake Components:
1. Remove the wheel using a lug wrench.
2. Inspect brake pads for wear; replace if they are less than 3mm thick.
3. Check rotors for scoring or overheating, replace if necessary.
4. Reassemble and torque lug nuts to specification (typically around 80 lb-ft).

4. Exhaust System Repair (if applicable)

Exhaust Leak Repair:
1. Inspect exhaust pipes and joints for damage.
