Tektro CR720 - Spring tension not equal - INSTALL HELP NEEDED
Maybe someone encountered this issue before and found a remedy. I just purchased a set of Tektro CR720 brakes for a CX bike I'm building. When I tried to install the Tektro CR720 canti brakes on the front fork I noticed that the spring tension for each lever is not equal. Even if I set the spring tension adjuster on the right canti all the way in and the tension adjusted on the left all the way out, I cannot get an even tension on both springs.
I've attached photos of the cantis attached to a digital scale to show the amount of force (in ounce) to pull it parallel to the ground.
I've contacted Tektro and they advised to use different hole for the spring pin but the fork only have one hole for each brake post. Again, the spring tension adjuster is not much help either.
Did I get a pair with defective springs? Please help.
This will qualify as a hack solution but I've changed spring tension by spreading it's rest position, or compacting the spring with vice grips. I have been surprised that it actually works, remains stable, ...if all else fails you could give this a try.
