I was having an issue with my brakes not contracting. it was front and rear. i replaced the master cylinder but now i have no rear brakes at all. abs light was on and went off now the brake light is on. front brakes work now but am not getting anything from the rears. Anyone know what the problem might be?

 

Could be the automatic Adjusters out of wak. Check this thread: https://dodgeforum.com/forum/1st-gen...37-brakes.html

 

yup sounds to me like you need to adjust the rear drums (since the auto adjusters are out i believe you will have to do it manually)
