it would be a shame if it bent when you needed to stop hard.
Why the L-shape? Why didn't you go straighter? The inside of the L is a weak point for fatigue. you could have made a rounder curve on the inside for more strength.
The L-shape was needed to clear the wide portion of the pedal below the attachment point, a straight link would not work. Correct, I could have used a broader radius on the inside curve. As for strength, I'm admittedly not a mechanical engineer with the means to calculate this sort of thing. The two L-shaped links are fabricated from 3/16" plate steel. My gut tells me there is plenty of strength in this application. I suppose I'll hit the brakes really hard at low speed to test it once the car is running.
