I have a 1996 Dodge Ram 3500 Cummings , My problem is the red break light on the dash wont go out,
I had a complete break job done about three years ago and the truck hasn't had many miles put on it.
So I was thinking that it might be the Master Cylinder that I installed not long after the break job was done because I was unable to bleed them, So today I took my truck to a shop to get the breaks bleed .Well that wasn't it.
I checked all of the fuse's all is good but that red light wont go out .
Any ideas ? .....................

 

Low brake fluid, proportioning valve displaced, or just bad. The shop that bled your brakes SHOULD have been able to solve that.

Erm, copy paste of the first post, completely ignoring what I posted?????

 

Make sure the emergency brake is all the way up.

 

thanks it isnt that.

 

I'm guessing ABS module is cooked

 

Now I have no idea what this is.

 

Now I know what you are talking about. but the red brake light doesn't stay on all of the time, Some times it will be out all day then the next day it stays on all day. How about a bad brake light switch.

 

Could be. That's why you need to get the code read, to see what the ABS system is whining about. Otherwise, you are just throwing parts at it, and that gets expensive.
