Hey fellas, I have a '12 sx4 AWD with a manual 6 speed, 136K miles on the clock and I need advice.

So in February my brakes felt kinda soft, I knew I was due for break pads, then the clutch went to the floor. I was right next to a reputable shop when this happened. Turns out my break reservoir was completely dry. The shop bleed the lines and filled it back up and everything was back to normal. While doing this they inspected the brake system and NO LEAKS could be found, I also have seen no leaks, pools, drips or anything of the sort after I got it up on all fours myself- zero evidence of a leak anywhere.

I kept a very close watch on the reservoir and everything seemed fine. My normal commute is about 7 miles round trip through town stop and go.

Then, I went on long road trips this weekend and last weekend approx. 450mi each week.

Still no signs of leaks anywhere and an empty reservoir. Where is my break fluid going? Is it going into my transmission via my clutch system somehow? The car behaves perfectly otherwise, this has been a great car I am really worried about her.

Thank you in advance!
