Slow Brake Fluid leak

Had complete brake fluid bleed and flush done last year at 85K at dealer. Since then, every 4 months or so I’ve had to add fluid, cuz brake light comes on, and reservoir at minimum. Been too lazy to track it down, but today I crawled underneath

The bleeder nut was loose, could turn it with my fingers…tightened it up…I hope this was the problem

 

Looks like you nailed it down. I'd bet that was it.

 

Looks like you found the problem. Have you checked the fronts as well? And all rubber hoses to ensure nothing is cracked/fraying?

 

Yes, thank you…Front brakes look fine, couldn’t find anymore wet spots…brakes seem to work ok…Had new rotors and pads all the way around at 65K (I’m at 100k now)…I do a lot of my own maintenance, but don’t have the confidence or expertise to do the brakes and feel good about it. But if they didn’t tighten this, maybe I should try doing it myself
