I have a set of BVM Brakes. I here to apply a small amount of grease to the o-rings that do the braking. I only have a standard valve, and I also have restrictors in the airline. I have not tested them yet, but the restrictors seem to apply air fast enough not to panic. Any input would help. They are on a CS Models X-terminator that weighs around 12-12.5 pounds.
