I have a 97 Lariat. Here is the problem. When I first get in and come to that first stop, my brakes are really touchy, and will lock up at times (if it is wet) after I use the brakes a couple of times they seem to work fine. I don't know if it is something in the ABS system. The front brakes are fairly new (rotors etc) I have not checked the rears however. Also I don't know if this is related but there is quite a bit of shaking when I do step in the brakes (as if a rotor is warped). Any suggestions?
