the QR function on my Zero Gravity Gravitas brakes is very tight. I has gotten a squirt of oil, but didn't help. Any suggestions what might be wrong?

Mine have always been a little hard to use but I found if I manually squeeze the pads to the rim with one hand the lever moves easy. You can always send them in for service, their customer service is excellent.

I have a set that I can't get the release to work. I always thought it was because they are powder coated white and not anodized. The white paint might be causing the problem.
Ted did tell me to send them back to him and he would take care of it, but I never did. I should do that this winter.

Edit...I think there is a tiny "Jesus" clip holding that together. If you feel comfortable working on it you could take it out and clean it and put it back together. Probably do the trick. Work over a sheet of white paper or something to ensure that you don't lose anything.
