10K riding would likely result in brake pad wear sufficient to lower the brake fluid level without any leakage. I would advise checking the brake pads to ensure they still have the material required to stop without causing damage to rotors. pads are cheaper than rotors. Follow the owners manual for instructions as to how to check engine oil level. I check and adjust the air pressure in my tires the first of every month.
