They seem to be the ultimate disc brake for a tandem; unfortunately our current tandem does not have disc brake mounts so I have to just keep them on my single, but WOW!!! It is the brake power and feel you dreamed of for a tandem. So much confidence and control. The Hy/Rd is a quantum leap in disc brakes. I use them with Avid HSE rotors and they are dead quiet too, just a slight woosh sound and no squeal EVER!
You are experiencing the problem we are all having on the tandems in that the reservoir doesn't refill all the time and they don't adjust for pad wear. The return spring is not strong enough. Also you
can make them noisy on a tandem,you just need a big enough descent.
