02 750 front brakes groaning

i changed the pads on the front of my bike. long story short after i put new pads on and flushed my brake fluid my front brakes groan when i lightly get on the brakes at about 5mph. they also do the same thing when i take off slowly sometimes. only mods to the brakes are redline race fluid and SS lines. thanks in advance guys Joel

you posted that a month or so ago but when i put fresh pads on i find flat concrete somewhere and rub them in a figure eight to roughen up the surface a bit. fixes the squeaks everytime. goodluck
