Hello, my name is***** the brake pedal is very hard then the issue is the brake booster. This is what provides the brake assist to allow the pedal to be easier to press. I would make sure that the hose from the engine is connected to it and that it is connected firmly to the engine. If it is then the booster is the problem. I hope this helps. Please let me know if you need more help.

There is not an electrical issue on this vehicle that will cause this to occur.
