Ok, so I was bleeding out my entire brake system after replacing my master cylinder the other day, when I realized that my brake line has a hole right before it bolts into the wheel cylinder on the passenger side. When I went to AutoZone, they tried selling me a hose with the attachments on the end for a caliper, which couldent have been the correct part, seeing as how cherokees have rear drums... what do I replace this line with? Is it just 3/16 brake line that I need to flare nuts onto and bend around my axle? And if the passenger side rotted through, should I also replace the drivers side? Its an 89, so everythings pretty rusty.

 

Might as well replace both while you are back there, and yes it is just 3/16 with flare nuts on both ends.

 

I'd pick it up pre-bent at the dealer. My local dealer had the entire rear brake line system. i picked it all up for about $60. When I need it, it's there.

 

I still have plenty of 3/16 hand bendable line laying around from doing the master cylinder. Ill take out the old line, cut of the nuts, flare them to the new line and see how that works.
