The first thing to check is the pads. You should be able to look at the them and see how much actual pad material is left. If there is only backing plate is left then its time for some new pads.

If its not the pads its possible that some air got into the system. Its possible that the reservoir no longer has fluid to supply. Check the the level in the rear reservoir to see how low it is or if there is even fluid left.

I would do some research on how brake systems work so you can get a better understanding of what is there when you look at.

It may be possible that the pads and disc could have picked up a bit of overspray of chain lube. If that has happened then new pads and thorough cleaning of the disc will help. Some cleaning chemicals or polishes can also contaminate brakes.

Even if the pads are not worn out it may be beneficial to change them if they are a few years old.

I have always thought my rear brake is less powerful than many other bikes I have owned. Maybe it is made weak deliberately by Honda so that new riders will be less likely to lock the rear wheel?

I'd bleed the system anyway.

You could pull it apart and check the condition of the pads, or replace them with something better, and de-glaze the rotors. It's possible, if you use it a lot, that the rotor and pads are glazed. Clean the caliper and lube the sliding pins.

Check the adjustment to make sure there isn't too much travel required.

If you find yourself using the rear brake aggressively, I would start working on using the front more. That's the one that does the job when you really need it.

For me, it's like there's no rear break!
While I don't use the rear brake for much, I do want it to work.

Last season mine completely stopped working (on my SV), and after some bleeding came back and worked fine the rest of the year - but I will check it again before heading out this season.

I would do the checks recommended in the posts above. You want it to be fully functional even if you don't rely on it most of the time.
