Hello, New to the site, you guys are a great resource. When driving my 87 gn, the brake light comes on occasionally, cycles in less than 2 secs & goes out. Following your troubleshoot chart, the switch appears to be good, as are the fluid levels. With the system de-pressured, it takes about 8-9 secs to pressure up with the ignition on. It appears to be the accumulator, but I was wondering if you guys w/ more experience could confirm this before I shell out for a new one. Thanks for your help, Dave

Sounds like classic signs/symptoms of the accumulator bulb being weak. I think Kirban now is selling new ones for about $130.
