I'm not trying to be patronising but I don't think flying just three return trips per annum is enough to be able to judge whether or not your experiences at Birmingham were out of the ordinary. When it's windy you get a 'wobbly' approach. You may not find it pleasant but the experts in the cockpit are more than able to deal with it. Try the approach to Belfast City on a dark January night in a howling gale. Now that's wobbly!! I fly frequently and I have experienced some very strong braking. In my experience it's normally to allow the aircraft to use the first available exit from the runway.
