Solution

1. Preparation

Gather tools and parts needed for repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Check and Change Engine Oil

Sub-steps:
1. Remove the oil drain plug using a socket set and allow the old oil to drain completely into a pan.
2. Replace the oil filter using an oil filter wrench.
3. Install the new oil filter and tighten to manufacturer specifications.
4. Replace the oil drain plug and torque to the specified value (usually around 20-25 ft-lbs).
5. Refill the engine with fresh oil through the oil fill cap (consult owner's manual for oil capacity).

3. Inspect and Replace Coolant

Sub-steps:
1. Check the coolant reservoir and radiator for proper levels.
2. If low, mix a 50/50 solution of antifreeze and distilled water and refill to the proper level.
3. Inspect hoses for cracks or leaks and replace if necessary.
4. Bleed the cooling system if air pockets are suspected.

4. Brake Inspection and Replacement

Sub-steps:
1. Remove the wheel to access the brake components.
2. Inspect brake pads for wear; replace if they are worn down to 3mm or less.
3. Check the brake rotor for overheating signs (blue discoloration) and replace if necessary.
4. Reassemble the wheel and torque lug nuts to specification.

5. Belts and Hoses Inspection

Sub-steps:
1. Visually inspect all belts for cracks, fraying, or excessive wear.
2. Replace any defective belts with new ones, ensuring proper alignment and tension.
3. Check hoses for swelling or leaks and replace any that are damaged.
