Hello all, We also had an issue with our airbrakes and it was caused by a build up of polish residue and gunk on the air brake box's trailing edge. Near impossible to open them till washed out and cleaned thoroughly with avgas. I think G. Vertigan posted pictures on the topic and what our cavities looked like some where here. The amount was almost negligible but once removed all was good again.
