The oil should be at the appropriate level on the dipstick and the oil should be relatively clear and amber in color.

Transmission fluid should be checked every 30,000 miles or two years, whichever comes first. Check the fluid level with the engine running and the transmission in park or neutral. The fluid should be a clear, pinkish-red color, and if it appears dark, burnt, or has a foul odor, it may be time for a transmission fluid change.

Brake fluid should be checked every 12 months or 15,000 miles, whichever comes first. Check the brake fluid level in the master cylinder reservoir and ensure that the fluid is at the recommended level. The brake fluid should be clear and free from contaminants, and if it appears discolored or has a milky appearance, it may be time to flush and replace the brake fluid.

Power steering fluid should be checked every 12 months or 15,000 miles, whichever comes first. Check the fluid level with the engine running and the power steering reservoir cap removed. The fluid should be at the recommended level and have a clear, amber color. If it appears dark or discolored, it may be time to flush and replace the power steering fluid.

Finally, coolant should be checked every 12 months or 15,000 miles, whichever comes first. Check the coolant level in the coolant reservoir when the engine is cool and the vehicle is on a level surface. The coolant should be at the recommended level and appear clear and green or orange, depending on the type of coolant used.

It's also important to check the brake fluid level regularly. Low brake fluid levels can cause the brakes to feel spongy or unresponsive. Make sure the brake fluid reservoir is filled to the appropriate level and that the fluid is clean and clear. Dirty or discolored brake fluid should be flushed and replaced.

Another important aspect of brake maintenance is having the brake system inspected for any leaks or damage. Brake lines and hoses can become corroded or damaged over time, leading to leaks and decreased brake performance. A professional mechanic should inspect the brake system for any signs of damage and replace any worn or damaged components.

Finally, it's important to have the brake system serviced on a regular basis, typically every 30,000 miles or as recommended by the manufacturer. This includes having the brake pads and shoes replaced as needed, the brake fluid flushed and replaced, and the brake system inspected for any issues.
