Ensure the vehicle is parked on a level surface and the engine is turned off and cool.
Disconnect the battery for safety before working on any electrical components.

2. Fluid Leak Repair

Sub-steps:
1. Identify the source of the fluid leak, noting the type of fluid (oil, coolant, etc.).
2. If oil is leaking, replace the oil filter and tighten or replace oil pan gasket if necessary.
3. For coolant leaks, inspect hoses and replace any that are cracked. Refill with manufacturer-recommended coolant.
4. For brake fluid leaks, inspect lines and fittings; replace any damaged components.

3. Replace Worn Belts and Hoses

Sub-steps:
1. Remove any obstructions to access the belts and hoses.
2. Inspect each belt for fraying or cracking; replace if necessary using a new belt of the same specifications.
3. Check hoses for any signs of wear and replace them if they feel brittle or show leaks.

4. Brake System Maintenance

Sub-steps:
1. Raise the vehicle and remove the wheels to access the brakes.
