just had new brake lines put on & rear caliper rebuilt 1200 miles ago.. while riding over weekend i stopped.. for whatever reason put my hand on rear rotor.. very very hot.. and my foot was no where near brake lever.. when i got home put bike on center stand.. looks like pads are rubbing in 1 spot of rotor when i slowly spin tire.. thoughts? a very good shop put the lines in, and have a very good reputation, I've been using shop for 10 years.. called owner, bringing bike in tomorrow.. I've checked fronts after ride.. they are hot, and should be.. i use them all the time.. rarely use rear.. FYI: rear master cylinder was not changed out..
