2001 1500 with rear drum front disk. The check break light is coming on. Had the rear breaks done a couple weeks ago(by a friend) and the fronts about a year ago. There is some intermittant drum noise coming from the passenger rear. Just need some advise on what to look for. Breaks seem to be working good. As always any advise is appreciated.
Thanks/Jim

 

You have a leak in one of the rear brake lines or wheel cylinders.
