umm no idea...how bout if the low temperature caused the aluminium caliper
to contract and grab the steel piston (are pistons still steel?) , until the
brake warmed up ?
or the piston might be jamming due to uneven pad wear or some such
are the circuits that release pressure when you let go the brake lever
working? (or is yer master cylinder full of crap)<< this may or not be
temperature dependant i spose
how far do you pull the lever in 'normally' when you are braking?
AAH!! if its an old bike and you changed pads recently without cleaning the
pistons properly maybe the crap on the pistons is now jamming in the caliper
bore<< maybe but the problem should get better as the pads wear
