My '05 has been running great however yesterday I noticed while driving that when I hit the brakes it felt pretty soft and I had to push the petal down much further than usual. This seemed to be pretty random though as certain stop signs/lights I would stop fine, others I would have to jam it down pretty hard to stop the vehicle.

I haven't pulled the tire yet to inspect further but visually I don't see anything out of the ordinary like leaking anywhere or low brake fluid. There is a hose thats near the frame by the front left tire thats not really attached to anything (it just abruptly ends with a solid cap as well) thats clanging a bit as it isn't secured though I can't figure out what its for (it ends near the end of the tire and runs forward on the frame where it crosses over and underneath the engine). I'm going to try to get a photo of it this morning as you can see it through the wheel well.

Years ago one of the pistons seized in the drivers side caliper which I replaced the entire unit at the time. I've got fairly new pads and rotors installed as well.

Other then grabbing the photo of that mystery hose thats not secured - any recommendations for initial diagnosis? I called my local shop to check their schedule in case this is something bigger than what I have time or skill to handle but they can't see it until at least Monday so I figured in the meantime I would reach out here.

I've got a scantool attached and theres been no codes at this point either.
