lol, i've just been out aswell. nearly crashed twice so i thought i'm sure i've read somewhere snow + abs is a nightmare so i dissconntec the white plug on the res. fook me how dangerous is that!
i thought i'll just try the brakes and it just slid towards a wall. missied it by less than 1/4 of a inch, i then stopped re-connected and carried on my way! although when the abs kicks in it seems to brake more at the rear as the rear kicks out a bit..
