ABS and tail lights

[rockyrunner99]

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

You got a switch on the master cyl?

 

[rockyrunner99]

yes. Is that not just a low brake fluid level indicator? The brake fluid is fine, well it is full, it should probably be flushed.

If its just a switch at the bottom of the m/c, thats just the level sensor. Concentrate on the "BOO" switch on the pedal assembly. If its shorted, your brakelights will stay on constantly.

well It was the brake light switch. Easy to change, I had never heard of one going bad before. Thanks
