I have a 95, auto,4X4, with 101K miles, and pretty much straight stock. Early last week I noticed that my E-brake light and ABS lights would stay on, and then after a couple of short trips would go out again. I was ready for new brakes which I had done at the end of the week. First symptom of a problem occurred after the weekend when about every third or fourth time I used the brakes I would get a shuttering that would be similar to that which would be experienced when driving on a wash board roadway. This morning all was OK for a few miles down the highway at 60 M. P. H. when a minor shuttering started and grew in severity. I applied brake pressure and it became worse. I pulled off the road to check if anything was visibily wrong, but saw nothing out of the ordinary. I continued my trip and even though some shuttering was felt, it seemed better. At the next stop I made, I disconnected the ABS plug-in at the master cylinder, however the problem is still there, but again just comes and goes. I have an appointment Wednesday morning with the Mechanic that did the brakes, but I was wondering if any of you out there might offer some ideas on what it may be. Thanks in advance.
