I have been having brake issues. I thought it was the master cylinder. THe pedal has had more travel than it should. When I pushed it it woudl fell like it started to grab then would let loose and then grab later. It feels like the back brakes are not working correctly. Well when I came out of work today. The battery was dead, even though the lights were not on. After getting it started, I realize the tail lights or brake lights are on all the time, even if the light switch is off. Also the ABS light is on. I have not done any thing yet just thought I would get suggestions of where to start. thanks
