I agree with Wayne. I have had several expierences with the rubber lines
collapsing and holding the brakes on or causing them to drag. If the rubber
lines have never been replaced I would highly advise you replace all three.
You could take the line off on the bad wheel and trying to blow through it
for a quick test!
