I just bought my first road bike over the weekend. I installed the front brake, and this morning I noticed that when I brake hard I hear a popping sound coming from the brake. Any ideas on what may be causing that or how to fix it?
When I installed the brake I noticed there were two washers with kind of serrated edges right behind one another on the bolt that attaches the brake to the fork. I left them both on there, but I noticed the rear brake only had one. I don't know if that's an issue or not.
I also am very scared of tightening the brake so hard that I crack my carbon fork, is that a possibility? I don't have a torque wrench, but I tried to estimate the proper torque to apply (max 87 in-lbs, I think) by using a 5" allen wrench and estimating about 20 lbs of pressure.
Any help this morning would be greatly appreciated since I'm riding this bike home. Thanks.
