Thats what I thought...

IT should not be this hard!....I pulled it forward and lowered it down - as in both the levers sprung back and the r/h/s started to slide down but the left would get completely stuck.  I put a dab of grease on it, no value.  I finished up removing the lug on the left hand side and got it back in.  I'll have a look at it in case its got a burr or something....
