Re: Brecoflex Treads
It's been a long time (2004, I believe) since a team I was on used treads, so take this for what you will.
As noted, back in the day Brecoflex treads did have a bit of a strength issue, so we didn't use them. We used treads from Mectrol that had the same backing as the Brecoflex treads, but they were Kevlar reinforced and had a failure strength in the area of 1500 lb. We never had one fail (and if you saw our 2002 robot in Ken Patton's / Paul Copioli's drivetrain presentation, you would realize how impressive that is).
I don't even know if Mectrol is still in business, but I'm sure you can find some treads with the Kevlar reinforcement that will help keep them from breaking.
