I have a 88 4runner and it has a brake leak on the passenger side. Had a friend look at it and said the line was next to the gas tank so he couldnt really tell how bad it was. Is this a possible simple fix? Or could it be a valve?

 

A bit more info and knowing your mechanical aptitude would be helpful. Find out exactly where it is leaking from, take a picture if possible, and we will help you from there. Generally speaking the hardlines are sectioned, so replacement is not that tough. I would bet it is leaking from a fitting vs. the actual hard line itself.
