Peter, i have had the same prob with my booster and fixed it by taking it out and pulling it apart and cleaning the inside with a dry cloth. Check that the diaphram has no holes or splits in it, wipe some oil aoring the inside and reasssemble, i have done this my 81 rr about 8 years ago and still going strong, also did it to my 85 rr about 2 months ago when i replaced the brake m/ cyclinder. I also have a crack in the B pillar just above the waist line.
Regards,
Nick.
