V Brakes squealing on my tandem

I'm not a big mountain biker, so I don't deal with V brakes much. But my new tandem has them and they are squealing and sticking in the back. I've put on new pads with metal holders and also thoroughly cleaned the rims and worked them over with a scotch brite foam sanding block. They are Mavic Aluminum rims. I've toed the brakes a bit, but still doesn't seem to help much. Also cleaned the rims with goo gone and then alcohol.

Are there some secret V brake voodoo steps I am missing?

I've got Koolstop pads, but I am going to SwissStop green as soon as these are worn out since they are my favorite brake pads. Do you think that might help any?

I've never found a solution that works 100% of the time. Lots of things seem to work on individual cases. The first thing that I always try is to dress the brake pad with a fingernail emery board. That works about 85% of the time.

The things that you've done all work some of the time so it's good that you've tried them. New brake pads might help. Don't throw away your Koopstop pads because they, for sure, will work on another bike.

Tightening the bolts that hold the brake arms is worth a try. On my own personal tandem I eventually solved the problem by replacing the brake caliper arms.

And the answer is...

SwissStop green high performance pads. No squealing, no melting pads and good stopping power. Did the trick for me.

I have never been able to get KoolStops to be quiet. Many others on this forum have had better luck. My advice; why listen to all the noise, dump them now. bk

I've had a heck of a time with Kool Stop salmon-color pads on new aluminum rims. Two different bikes, same symptoms, incredible noise. I switched to black pads and the noise went away. After a while the rims wore smooth, so I'm hoping the salmon pads will be quiet now. I just put a set of them on my bike in preparation for this weekend. I'll find out tomorrow if they're OK.
