So tomorrow I'm hopefully going to be picking up a 1991 Brougham 5.7. Its not in the best of shape cosmetically, its got a fair amount of rust, but mechanically it seems fine except for one little thing, he said the brake line going to the pass. side front has a leak. Now he has offered to let me use his driveway to fix it but its only about 2 miles to my house from his. So i guess my questions are, do you think i could make the drive home using the parking brake? Or if i decide to just fix it there how much is involved in replace/patching a brake(I've never done it before, though i am fairly good with repairs)? Any input would be helpful,l thank you
