TRP HI/RD Hydraulic Disc Brakes installed!

First impression on TRP HI/RD: smoother and quieter than Avid BB7 road.  These got installed on my 2014 Specialized Roubaix SL4 Disc.

I got tired of the squeaking, whining, and grinding of Avid BB7 Roads.  I tried new discs and new pads - and the problem never went away.  After a big descent or a ride in wet conditions, the BB7 disc brakes would start obnoxiously screaming.

Original setup:

I had a similar problem with BB5s and then BB7s on my 2013 Specialized Tricross Steel Disc.  The problem was even force due to flex of the steel frame.


More on these after riding a while.
