    I drove the car home, parked, and lifted the hood to check and it was filled nearly to the brim of the cap. So I took it back and argued with them back and forth until they took the amount out to the max line. They were huffing and puffing about how it's okay, and then I asked them to show me how this is okay, the service advisor couldn't even find the reservoir. They admitted some junior technician worked on it. Rectified the issue by drawing out the fluid and replacing the ripped cowl gasket. I would've done it myself if I had a turkey baster lying around.

    Also, I think Car Care Nut was correct in that some dealers may not bother with techstream when it comes to bleeding brakes. I spoke to one of the junior techs on their lunch break for advice on future brake bleeds, and he told me that he never uses the computer to bleed the brakes on hybrids unless a component was replaced. Just uses a vacuum pump. I was a little shocked to hear this. *sigh*

    Before I dropped off the car, the brake fluid was in between min and max. Like right where the seam of the reservoir is. Why should I return it to that level by the way?

    Ideally you want to leave the level as you found it.

    The car rolled off the factory floor with new brake pads, and the level at the full line. As the pads wear the pistons move out, and level drops. It tends to be near the low line when the pads are near the service limit (1mm).

    There's no harm in topping it up to full line, but down the road if putting new pads in, when you push the pistons back (to clear new pads), you'll need to keep an eye on the reservoir, it might overflow.

    Dang, sorry to hear about the brake and dealer problems....I'd be mad, too!

    I got involved in my own brakes around 2002 when I took a hand-me-down car my Father-in-law gave to us (92 Subaru) to a local Brakes Plus to fix the squeaky brakes. Idiots charged me, probably, 3 times too much and I had to take it back a number of times because they left air in the brakes and it would pull hard when using them. I worked with a guy who did his own and he taught me when he did my Tacoma...it's really not that difficult and, now, there are tons of folks on YouTube who teach so many car repairs. The hardest part about car repair is when things go wonky and you encounter problems you've never seen before. (Like a bolt that breaks or something so rusty you can't get it out, etc.) It's good have friends you can call when you get in a pinch!
