Flex lines are 'normal' rubber; but fairly new. I checked the hard
line today; no kinks (my memory was playing tricks again).<br>
<br>
It pulls down straight; looks like replacing the kinked RR hard line
might have helped (ya' think, Bob?). I'll pull the wheels and have a
look at pads and rotors; might be a while as I'm starting to think
about harvest.<br>

Your $0.02 is appreciated. Rotors and pads were replaced not too
long ago, but it's probably been 20 years since I rebuilt the
calipers.<br>

<div>Maybe the right caliper was fluid starved for so long
that is froze in place or at least is binding up for that
reason. If all the brake lines are clear, the only thing
left is the caliper. Sounds like time for a rebuild. Just
my two cents.</div>
