To rebuild, or not to rebuild (brakes)

Fall 2008 I picked up a good deal on a set of Galfer Stainless braided brake lines (front+rear), as well as a 1997 YZF600R front master cylinder, as well as a set of EBC HH sinstered pads. I installed the pads last summer (a shipping accident left me with a spare set of brake pads :banana: ), but I haven't put the brake lines or new MC on yet because I wanted to rebuild the calipers and master cylinders when I installed them. None of the calipers leak, and none of the stock master cylinders leak. The YZF MC is one I won off of eBay, along with a set of blue-dot calipers (long since sold) for a steal of a deal, and when I took the lid off of the reservoir, it was still holding brake fluid.

My question is this: with my bike being a 1997 FZR600 that was taken pretty good care of, do I honestly need to rebuild the master cylinders and calipers before I install the new brake lines? Or am I just being a little too CDO* about it?

Seals for the calipers aren't too expensive, but the master cylinder kits are pretty freakin' expensive, even through the discount dealership in Texas that I usually use.

And on a side note, I'm going ahead and installing a pressure-based rear brake light switch while I'm at it, so I can install these Woodcraft Rearsets I got a little while back (and replace this faulty stock brake light switch...it sticks open right now).

* CDO = the initials for Obsessive-Compulsive Disorder, listed in alphabetical order--as any Obsessive-Compulsive person knows they should be.

A good cleaning and new seals would not hurt anything and will give you the piece of mind in knowing that they are as good as new.

So just leave the master cylinders alone and clean the calipers?

I was speaking of the set up as a whole. If it were me though, I'd try everything out and see first. They may be fine already and you won't have to clean them for a while...a long while.

If they look ok then I wouldn't worry about it...unless of course you're bored and have cash to throw around.
