If you're talking about the small metal lines that hook right to the rear calipers..they get replaced because they don't like to come off easy..like to round off..if they come apart then they should be ok..but if you get them with the kit then they can be replaced..totally up to you and what happens! Rich

Dave, you can visually see some imperfections by having the caliper mounted.....spin the rotor 360 degrees ..........while spining the rotor watch the clearance between the caliper and rotor. See if the rotor travels evenly between the pads. If it gets closer at times to one side or the other ..........the run out is off. On a different note the rear steel (or stainless) lines are available individualy. There is a right and a left. Also, I would replace the rubber lines with the better reinforced braided lines. another note: dial indicators are cheap..........Harbor Freight, but you also need a magnetic base or clamps to hold it's position. I'm not sure if Auto stores rent them out or not. Are we all helping or messing with your head?...........I hope we're helping.

Oh, you're definitely helping, 440HP    All of you guys are.  This is such a great site for this kind of thing.  I do have to use judgement on some of the suggestions - if I followed all the great advice on this site I'd probably be broke by now.  Example: braided lines vs. rubber.  I totally agree the braided ones are better, but they're more than double the price.  So I'll most likely make a small sacrifice there and go with rubber (the ones on the car lasted this long).  But that's not to say I don't appreciate the suggestion - keep 'em coming!  

The reason you would want braided over rubber is pedal feel..there is a difference there..the braided lines give you better pedal feel..as in you get faster response from the brakes..not so much on how long they would last..that's not really a big deal..they both have rubber inside that can come apart..a dial indicator from the HF would work fine...I haven't seen measurement tools made here in a long time..so why pay the big bucks for something like that anyhow..I got one that uses a vice grip to attach itself to whatever is being measured..works good on things that are not magnetic..it has a snake style arm that makes it very easy to get the indicator where you need it..no big deal though..get what they got there and it will work fine!!

Thanks, guys!  I think I'll go pick up the dial indicator and magnetic base from HF!  Should work out pretty well....good tip.
