Gary, assuming the shutter has just become noticeable and no brake work has been done recently..chances are your rotors (discs) are warped.
It was fashionable at one time to always turn the rotors whenever you replaced the brake pads..some shops still do. It runs up the shop labor charges and costs "slightly" less than brand new rotors, especially on the front.
Once the 911 rotors have been turned they will warp eventually..you might get one or two pad "slaps"..then the rotors are a shuttering
Getting a magnetic dial gauge from Harbor Freight..jack up the front of the car...good time to check the front wheel bearings (see if the front wheel(s) have much movement grasping the top and bottom of the tire....pull the wheels (insert usual lawyer disclaimer here) install the dial gauge and check the rotors for run-out..
If your steering wheel is shuttering when braking..its the front discs..if the car shutters..then its likely the rear discs.
I have seen the rear rotors get turned more often than the fronts..probably because of the parts expense..that's when they will warp eventually too.
If your front wheel bearings are sound..just bit the bullet and replace the rotors.
911 brakes are a DIY job..unless your just not handy with tools.
If the rotors are original or old enough to vote..change the rotors, repack the front wheel bearings..pads..sensors..rubber brake lines and check the caliper boots..they get torn.
My winter project coming up..I can't wait:
