Re: what did you do to your motorized bicycle today?
I upgraded from a 2-piston Hydraulic front to a 4-piston TRP hydraulic brake. This one was a rear so I had to shorten the hose. It comes with a bleed kit too! $120 not bad at all for a quality single brake and nothing additional needed. Unfortunately my 2-piston wore right down to the pad backing and ate up some of my disc, so I had to replace the disc too. I liked the look of the old disc better, but this one is ok too.
This brake will also take the shimano heat sink pads. Nice to know as many shops carry shimano pads more than any other brake.
