front brakes
 

they seem to squeek at low speeds under fine breaking sometimes if it a bit harder get a little judder.i no this time of year does strange things to bikes only done 1500 miles so not worn breaks.i used break cleaner but that lasted a day i do ride in ALL weather so is that all it is????

Squeak is the back of the pads moving against the caliper- pop them off and get some copper grease on the back of the pad. Don't know what your judder is, could just be natural brake judderiness or could be a slightly warped disk (said the scaremonger)
