I have an issue just recently opened my hood and I've noticed to right side of engine drivers' side to far right I've noticed a frozen hose that I've never seen before like that. I have no clue to what or where it goes to figured a diagram with labeled parts would be of help to see if I can match the location.
I've also just drove and suddenly brake pedal went all way down haven't looked into to common problems for that would be yet I have trouble finding a manual online for free for my year make and model listed above sedan.

Hi,

As far as the brake pedal is concerned, chances are either there is a ruptured brake hose, or the brake master cylinder has failed. Take a look at this link. I feel it will be helpful and of interest to you.

Do me a favor. Check the brake fluid level. If it is low or empty, we have a leak. If there is still fluid, chances are the master cylinder has failed.

Next, can you upload a pic of the hose? Also, how large is it? You indicated it froze, so there must be a frozen liquid in it. Could it be the windshield washer fluid supply?

Let me know. A pic would be helpful for the hose. Let me know your thoughts and findings about the master cylinder fluid level and the link I attached.

Take care,

joe
