You will have to check for a mechanical problem, may be a seized piston, you can try and open a bleeder to see if it is a hydraulic problem, if the brakes back off with the bleeder open it will be a hydraulic pressure retension problem, if you have any doubts about working on braking systems,best to get a qualified mechanic to check this out for you.
