Losing brake lever pressure after sled tilts to the left

[tahoelocal]

Happened twice so far on my 9R. Once in a steep side hill and once when I was flipping the sled over. I lose almost all pressure in the brake lever. A few minutes later the pressure comes back and the brakes work fine. Can I add some fluid or do I need to replace all of it?

sound low on fluid to me

You can add. It's DOT 4. You may have to bleed, but I bet you'll be fine.

Also make sure the vent slits on the master cylinder are working as expected. Probably fine but good to keep it in mind.

Any time I've had a sled upside side for any real length of time, I've temporarily lost my brakes upon restart. Just pump them for a minute and they're fine again. Not so sure it is in need of fluid as much as design in the system.

As others said, maybe add some fluid. When you flip a sled its good practice to quickly pump brakes before taking off again just to make sure you've got solid pressure.
