Power brake boost failed; brake application required increased pedal force and distance to stop. Problem abated after 30 seconds, then recurred at next vehicle start- also subsided after a period of time. Took car to dealer who indicated that 2 supply lines to the brake booster had failed and cracked. Was told that repair would cost $150, but could not be fixed that day. Old parts available (including images prior to removal).
