Thanks for the response guys!
Did look into it further and turns out that I did need brake fluid and quite a bit.
I have had my brakes checked several times and just got new tires which I had them look at the brakes while the tires were off and I've been told they are still good. Wouldn't they notice a leak if they were looking at them?
I have 115,000kms on it.
I'll keep monitoring the fluid to see if it does go down to signify a leak.
