Bob, I am certain there are others on this forum who know better than
I, but it seems to me the foot brake pedal should have been removed as
part of the rudder pedal installation. It certainly does not sound
right that you cannot use your ‘right’ rudder pedal.
My 415-C has pedals and a hand brake on the floor rather than on the
panel.
The rudders do ‘look’ small, but I have landed in up to 34 knots
gusting cross winds and held the aircraft straight as I touched down.

What do I know, but could the brake pedal be fitted with a much smaller
"pad" - if he is using the original brakes, he will need to use his
foot to stop (unless he has arms like Popeye).
