So i just recently bought a new ef but the brakes are bad the brake pedal goes down all the way down easily the brakes work just a little bit but when the brake pedal is all the way to the floor, So i took off both of the front tires the pads were in good shape rotors had little tiny dots of rust on them not to bad.So after inspecting that I bleeded the brakes and the brake pedal still went to the floor,So maybe I thought it would be Master cylinder or brake pistons what should I check?I topped off brake fluid that didnt help either.Help would be very appriciated Thank you.
