Went downstairs to get something from the car and saw a large puddle of what i’m presuming is brake fluid. It can't be oil because my oil is dark right now (needs to be changed) and it feels like brake fluid on my hands. A few days ago I checked the reservoir as the brakes were feeling uneffective and noticed it was almost completely empty. Filled it back up and a friend looked at the cylinders while i was at work, but he didn’t notice any issue down there. Does anybody have any advice?

 

Jack up the car, take off the wheels, and LOOK AT IT.

 

Thanks but i've already looked at it with the wheels off. Thought i put that in the post. Was looking for pointers if other people experienced the same issue...

 

Rusted steel line, probably the one for front right. It goes along the k-member.

 

It's a failed brake part. Probably one of:

Steel line
Rubber hose
Caliper
Prop valve
Master cylinder

Wherever the fluid is coming from, that's what's bad. Whenever I've had that issue, which unfortunately has been quite a few times on quite a few vehicles over the decades, I simply LOOKED AT IT, located and observed the source of the fluid, and proceeded from there. Not sure what other options there are for handling it, or what difference it makes to YOUR situation, which part(s) have failed on others' cars.
