On my 2005 gmc yukon, after about 6 months or so, during braking, there was a loud grinding/slipping feeling, that felt like it came from the front end. after getting the brakes checked out, i was told they were fine. took the vehicle to another place, and they duplicated the sound and changed the rear brakes. didn't hear the noise for about a month, then it came back. still feels and sounds the same. took it back to the shop. they said the front brakes were fine but i wanted them changed anyway. so they did. noise still there. anyone else with this issue? the noise and feel occur when slowing down to a stop or turn from normal travel speeds on highway or roadway. *tr
