2006 toyota tacoma . abs brakes right front brake when slowing or coming to a stop @ times applying the brakes in a normal manner. the right front seems to lock up while the others seem not to brake @ all. and slid through a traffic light. took it to toyota 2/15/10 picked up 2/18 /10, could not duplicate . this has happened before when it was about1 to 11/2 years old was pulling a small trailer, i called toyota the said it happened because of pulling the trailer, so never took it in. it when this happens there is like a loud rumbling buzzing vibration coming from the right front. also ever since new the idle will run rough then speed up to run normal. at toyota they said its normal 4 a tacoma to run like that & there was nothing they could do to fix it. *tr
