It does sound like your accumulator is at fault. I changed mine a couple of months back for the same reason - 40 seconds to reach pressure from start up & was running every second brake application, although my brakes seemed fine but leave it & your pump will eventually burn out which is a whole lot more expensive to replace. The accumulators are a known failure item (the nitrogen charge wont last forever) but are easy to replace.
