Brake problem usually occurs after a turn when accelerating to about 20 to 30 mph. steering wheel began to vibrate when pressure is applied to the brakes, brake dash lights comes on and the brake pedal pulsates and goes all the way to the floor. sounds also are heard from the front brakes (rubbing and grinding). the vehicle will barely stop when this happens. thank god we are not going at a high rate of speed when this occurs, if so, we would not be able to stop the truck in time. problem always stops after we pull over and put the vehicle in park and turn the engine off. this has occurred on many occasions with recently several incidents in one week, otherwise it happens about once a month. we are afraid that the problem is getting worse and may lead to an accident. we love the vehicle but just want the repairs made before something happens. also, the airbag light recently came on as well. question; are there recalls on these problems? *tr
