Vibrating front fork when braking
We finally have got some snow here in the DC area. This only makes the commute more fun for me, but I've been having a little problem with my front brake.
When I brake even moderately, the front fork starts to vibrate really hard (maybe 3-5 times per second). It feels like the headset were ridiculously loose or something. My conjecture is that the rims are icy, so the brakes only contact the rims intermittently, but I'm surprised at how much it feels like the fork is flexing.
I have canti brakes and it's a touring-ish frame, though too small for me so I'm sitting kinda upright. Why does this only happen on the front brake? I can brake as hard as I want with the rear brake, even though the rack, seat tube, and brakes are completely clogged up with snow.
