I would suggest heating the pedal and bending it back. How far is it bent. If you heat and cool aluminum it anneals it (softens) - if you bend it, it will work harden it and make it stiffer (and more brittle too). If it is bent alot and you try ot just bend it back without annealing it - it will typically break. The trick is to go through a heat/cool cycle (anneal), bend it a little (work hardens it back to original strength) and repeat.
