I just encountered this EXACT problem. The issue was NOT the the pins that others have mentioned. These pins are on the switch box housings and do not influence the rotation of the perches upon which the clutch and brake levers are installed. Instead, if you loosen the two pinch bolts on the underside of the perch clamp, the perches should rotate.
My clutch lever rotated without a problem but my brake lever would not budge. The problem turned out to be that the bottom part of the brake lever perch clamp was very tight against the handlebar. Even after I removed the two pinch bolts completely and removed the perch, the bottom of this perch clamp would not budge on the handlebar. I had to tap it with a rubber mallet to release it from the handlebar.
During reinstallation, I put some silicone lubricant inside this perch clamp piece and then did not tighten it fully until it was rotated into the position I wanted. Then, I tightened the two pinch bolts to the specified torque.
For you, loosen the pinch bolts a lot and try using a block of wood or something to jar loose the lower perch clamp piece. If that fails, remove the perch completely to allow access to the lower perch clamp piece and then you can remove it and lube it like I did.
Good luck and I hope this helps.
