Re: Disc's without power

Took the Idol into the shop on Saturday to see if Robinson can figure
what is wrong with the discs. Previous disc brake bikes I built would
lift the rear wheel if you put the front brake on too hard. Not only will
this one not but the brakes sqeal so loudly coming to a stop that the
vibration triggers the fall-off detector in the Garmin. My guess is that
the actuators are misaligned vertically so that the mounts need to be
refaced. There had to be some reason that I got the frameset for next to
nothing. (25% of the going price) Refacing is fast and cheap if you have
the Park tools for it. But they are only worthwhile for a shop to buy
since all the rest of my bikes are rim brakes,.
 

Lack of power and noise is more likely oil contamination which is disks
real weakness they can’t tolerate any, a misaligned calliper or dinged
rotor would still have plenty of power just be noisy (tends to be swish
than honk) and vibrate though remarkably little in my experience!
