BF Ute Poor brakes when cold

[music189]

Hopefully you can Help just had the front pads replaced in my work ute BFII 1 ton ute at 70000kms discs machined as well now when cold the brakes are rs,it wont pull up till some heat is in the pads etc ,this ute runs fully loaded all the time and also the normal brake performance is not as good as before with much higher pedal pressure than before.Booster seems to be working ok, only difference is the pads

I suspect Metal king pads but are not sure

any ideas thanks for help if you can
