Hey guys, my brakes in my 93 TA have something wrong and I dont know what it is. When idling and moving forward(its an automatic) to get it to stop you have to press the pedal to the floor. To keep it stopped you have to continue to press it to the floor otherwise it starts rolling. When driving you also have to press the brake pedal far down. I dont believe it is the master cylinder because it was replaced not that many miles ago but almost 10 years ago.Any help would be much appreciated
