Is there any way of unbending a bent brake lever without snapping it?
Thanks.

So how does that work then?

the lever is very hard .. odd that it bends .. but by all means try bending back with out oxyasetelene and you will find out

do you mean the lever at the handlebar end or the drum end?

Now you mention it, it is odd. How is it that you can fall off and bend one like a banana but try and do it deliberately and it will snap.

try putting it into a vice and slowly wind the bend out using the full area of the jaws of the vice

only explanation i can muster is that the ally changes at a molecular level .. its perhaps like doing break lines on a car .. you can bend once but then its very hard to bend it back as the tube seems to harden once bent

correct work hardens the same as the seize scuff on a piston hardens like glass and wont hold lubrication and will seize in the same area
