2006 DODGE CHARGER User Comment / Complaint

I own a 2006 dodge charger r/t that has a recurring brake problem. there is a noticeably loud sound coming from at least 2 and possibly all 4 wheel wells. when the parking brake is engaged i have intermittent slippage before the car settles. and finally, when attempting to brake i receive occasional shuddering in the car. i have attempted to take the car into three separate dodge dealerships in the dallas texas area on seven different occasions and on six of those trips was informed nothing was wrong with the brakes. on my fifth service trip a brake job was performed, but has had no effect in fixing the problem. on the subsequent two trips i was again told that nothing could be found wrong with the brakes and that the noise was normal. this problem began at the 11,000 mile mark and has been deteriorating since then (currently at 27,000 miles). if nothing is done soon, i feel that i will need to unnecessarily and unjustly purchase an entirely new brake system for my car to ensure my driving safety.
