Today i instaled brakes and put grease on back of pads and other moving parts/ bleed the brakes and took it on a test drive. None the lest a loud grinding sound ant stoped at home to see pags were atarting to grind rotor. What should i do?

Welcome to the forum!

Can you describe how the pads are grinding the rotor a bit more? Did you by chance put a pad in backwards? Is it just the far inside or far outside circumference of the braking surface that is grinding? Is it a groove around the entire diameter of the rotor? Were the rotors machined/turned as part of the brake job? Was the grinding noise there before you did the brakes?
