For a while now I’ve had this very annoying squeak/vibration coming form my back disc brake.
I know the guys at work are getting sick of me moaning about it, but it’s very annoying and it sends horrid vibrations right though the bike frame. At first I thought it might be uneven wear on disc pads, and this by itself was causing this disc to vibrate as there was uneven pressure on the disc.

My second line of thought was, when coming off my bike as I do on many occasions, I’ve gone and knocked the disc and put a slight kink in it,so I swapped the front and back disc around, expecting the vibrations to start on my front. With no such luck the vibrations continued on the back.

I have had a few suggestions:
1) There could be an airlock somewhere along the line, causing the pads to clamp at different times.
2) When I dismantled the brake a while back I didn’t tighten the unit back onto the frame correctly.

No matter what I do I can not stop the back brake from vibrating.
