Hello

I am attempting to instal a set of avid ultimate brakes on my Moots Psychlo. I have ran into a problem with the rear left side brake. When I instal the brake on the post and tighten the bolt the arm will not move freely. I have taken several steps to try and solve the problem:

1. I have doubled check the the brake post measurements to ensure that I am using the correct washer for the 21 mm brake post

2. I have tried switching the brake from back to front and the problem is isolated to the rear left side.

3. I have switched the two rear brake posts but the problem persists on the left side only.

I am starting to think that it might be an issue with the frame and my next step is to take it to my trusted mechanic at my LBS but before I do that I was wondering if anyone has any suggestions.

I had this exact same problem on my Crux when installing the shorty ultimates. The brake mount was over painted and had to be sanded down before it would move freely.
