I was replacing the passenger side motor mount today in my new to us 07 yukon XL (which will replace our 07 Yukon) when brake fluid decided to rain on my face. (And an trip to the clinic cause I somehow got metal embedded in the inside of my eyelid, but I digress.) it only leaked when jacking up on the motor and the leak came from two hoses up by where you would grab the dipsticks and I went to bleed the brakes when done and im getting so much air. I need more fluid now to try again, it’s definitely an excessive amount of air. My question is why did those lines start leaking and do I replace them or can I repair them? Also I can’t find them on the internet. And also, there has to be air leaking back into the system from there right? Again they don’t leak any other time. Usually I’m pretty ok with vehicles but today has been something else. I’m sorry for the long ramble, I’m tired a bit delusional. Thank you for any responses. It’s that snap together plastic to hard line. If you look close enough you can see a drop.
