Can the rear brake pedal be brought higher?

Just got the sport boots (SIDI ST) and they restrict how much one can stretch the toe forward, a part of crash protection that that the boots feature. On the forward controls this makes pressing the rear brake a bit awkward. I feel like it the pedal was a bit higher, it might help. And, no, I don't want mid controls.

Thus, can the rear brake pedal be brought higher?

I remember a thread saying the pedal is adjustable.

Yes. The pushrod should have some threads that allow you to adjust the height of the pedal relative to the foot peg. You may need to remove the two large allen bolts to access the adjuster.
