Rear passenger side drum brake is leaking fluid bad out of this seal. Can’t find diagrams for it and I have no idea what needs to be done to replace it.

 

It's not leaking from there it's leaking from the wheel cylinder.

 

how would I go about replacing that

 

Pull the drum, wheel cylinder is in there. It is held in by two bolts (on the outside) and a brake line. The line is the most fun part of the job. They like to rust up, and tend to break off, instead of coming loose. (or, the nut will come loose, but, the line won't, and you end up twisting the end of the line off.....) Gotta bleed the WHOLE break system after replacement.

 

You also have to take all the brakes off. A quick Google search should bring up videos specific to your Ram

 

I got it all wrapped up and it’s driveable. When I was in there I noticed the parking brake cable was snapped so I just took it out, not the best idea but it is what it is. Still have to push the brakes to the floor for them to work but I got it home and I’m gonna bleed the brakes good tomorrow. Thanks!
