I got a bunch of aluminum tubing and some sheets. I was thinking of replacing the steel bar that connects the rear brake to the swingarm with an aluminum one. Do you think it would be strong enough to last for a while?? the last think i want to do is lose my rear brakes flying down a steep hill!

 

If it's thick enough and works for ya more power to ya!

 

I think it will work fine, show us how it comes out. Just build it stout enough!
