my 07 dodge Dakota lost its braking yesterday!
ABS is lit up and I have some minimal breaking power.
but I filled up the fluid then pumped breaks and it leaked out rear driver side wheel.

any way it can be diagnosed where it may be leaking from and how to fix it? just a hose ? or could it be something else that I would have to take the wheel off to find out?

 

So I guess your engine is running fine now? To answer your question, Yes. You have the truck. We don't. Take the wheel off, pull the drum off and have a look. My guess is you blew out a wheel cylinder. But, no way for any of us to tell you what exactly is wrong until you do some investigation yourself. If unsure of what you are looking at or how to remove the wheel and drum,, download the service manual or buy a haynes/chiltons manual. I believe this has been suggested before.
