The pad on the left side did not ride tight against the puck , it would shake on light breaking causing wheel to shake I called autozone , permatex makes a glue that goes on the back of the pad and sticks to the puck its waterproof and sticks tight . the car is fine heres the best part the dealer said the non serviceable torque struts were alittle loose that was maybe the problem, they wanted $1000.00 to fix the glue cost 2.50 thanks for your input !
