short of having to get a whole new brake set, ask your bike shop if they can add some shims to your brake levers. This willshorten the grip somewhat. Ideally short of running up suddenly on a bike or stop light you shouldn't be using your brakes that much, However if you are riding with your hands wrapped around the brake levers this can lead to psin. As for the elbows, it may be a comination of any of these four factors, locking your elbows, the new position, fit and or lack of shoulder and upper body core strength. You can do a lot towards building up core strength by doing planks and pushups on a regular basisi.
