try to rig the nozzle of a shop vac to the part where the bag would normally connect and run the sander simultaneously with vac for a few minutes and see if that helps

Maybe you can use a linked belt to replace it. Check the width of the old drive belt, and give these folks a call: Lee Valley

I found a PDF file on Sears.com website for the original manual for my belt / circular sander.

My answer comes almost a year after the original question, but I'll post it anyway for those who end up here after a search.
Black & Decker no longer supplies drive belts for the BR400 sander, but you can get a replacement elsewhere if you know what to ask for.
The belt is a synchronous, single-sided "XL" series belt, and mine had 120XL031 printed on it. The belt width is 0.31in or 5/16in or 7.9mm. Its pitch (distance from tooth to tooth) is 0.20in or 1/5in or 5mm. Its total height is 0.09in, and tooth height is 0.045in. It has 60 teeth, making the total length 12in.
I found a replacement at sdp-si.com, part number A 6R 3-060031.
Look here for timing belts (inch), then narrow the search for single-sided, .200 (XL) pitch, 60 grooves, 5/16 width.

On my model 315.11720 3"x21" Craftsman belt sander to change out sanding belts you push the front roller in until it clicks to lock in its retracted position (a pry bar may help here), switch out sanding belts then unscrew the tracking tensioner a bit on the opposite side with a allen wrench until the roller snaps back in place. I never remember anything about using a screw driver to force it back forward position again. Then readjust the tracking if necessary with a few short sanding load tests and you're good to go. Oil is dropped in the front roller center by removing the flat head screw - it should say "Oil Here" around the screw.
