Is the noise actually coming from the pedal or from the brake pads themselves? If it is coming from the pedal you can lubricate the connecting point at the pedal with some spray lube. If it is coming from the pads when you step on the brakes then you may need to change the pads as you could be hearing the wear indicators. If the pads aren't worn then you may need to remove the pads and clean the back of the pads and lubricate the mounting bolts. If you lubricate them then you must use brake grease on them as it will not melt at high temps.
