Replace seals/gaskets: If leaking fluid is identified, replace the necessary seals or gaskets. Use torque specifications as per the service manual.

3. Brake System Inspection

Remove wheel: Use a jack to lift the vehicle and remove the wheel to access the brake components.
Inspect brake pads and rotors: Check for excessive wear or damage. Replace if necessary.
Reassemble: Reinstall the wheel and lower the vehicle.

4. Belts and Hoses Inspection

Check belts: Look for fraying, cracks, or signs of slipping. Replace if damaged.
Inspect hoses: Check for any bulges or cracks. Replace any damaged hoses.

5. Transmission Fluid Check

Locate dipstick: Find the transmission fluid dipstick (if applicable) and pull it out.
Inspect fluid: Check the fluid level and condition. If burnt, drain and replace the transmission fluid.
Refill: Use the correct type of transmission fluid as specified in the owner’s manual.
