Okay so I have a 2000 jeep Cherokee, I was checking out the undercarriage and noticed that the brake lines were very rusty but not yet leaking. I also noticed the front left hose connecting to the caliper is leaking a little bit. I want replace the lines, and from what I read I think I'll get the poly aemor brake lines from the atore. As for the hose I'm having a hard time finding a replacement part. Also any advice doing this job would be great, ive never done any brake line related repairs before

 

Bleed the brakes when done is the number one thing. Take your time when removing brake lines, they are known for rusting to the fittings, and breaking or bending the line when attempting to loosen. Soak in WD40 for a few days before to hopefully minimize this from happening.
