2. Inspect brake pads and rotors for excessive wear or overheating.
3. Replace worn brake pads or rotors, ensuring proper torque specifications are followed for caliper bolts.

4. Replace Damaged Belts and Hoses

Sub-steps:
1. Visually inspect belts for fraying or cracking and hoses for bulges or leaks.
2. Remove any damaged belts using the appropriate socket and tensioner tool.
3. Install new belts and tighten to manufacturer specifications.
4. Replace damaged hoses and secure with clamps.

5. Check and Replace Transmission Fluid if Necessary

Sub-steps:
