If the motor keeps running, it's because the pressure switch is bad (screwed into the top of the brake assembly) and is not opening up thus the pump never shuts off. If you sit stopped long enough with your foot on the brake the pump will generate so much pressure that the motor will stop and begin to burn up. It should then blow the fuse on the fuse panel, and the pedal will drop. You'll have some brakes, but I wouldn't drive it around in this state. Now if the "brake" light has been flashing on briefly when you step on the brakes, it means the accumilator is going bad. It's the big round ball screwed to the side of the brake assembly.
While you can find these parts seperately, if you go to AutoZone they can order you the entire brake assembly, rebuilt by A-1 Cardone. It's around $200, but has all the parts you need. I would just swap the switch and/or accumulator, and keep the rest of the brake assembly on the shelf. If you are trying to keep the car somewhat original, this is the way I would (and did) go, as I have an '87 GN myself.

i agree

these brakes dont last. im on my third . i have an 87 gn, my brother has an 86 t type and switched to a vacuum conversion setup. his is more reliable, but doesnt stop half as well.if you dont mind crappy brakes, make the switch. if you want good breaks, it will cost you.

Had A Customer This Week With The Same Problem And It Ended Up Being The Pump Motor Itself. It Wasnt Producing Enough Presure So I Changed That Pump/motor Assembly. This Pressure Ball Was Also Deplated Of Nitrogen So It Was Also Changed And That Kept The Light From Flickering On After A Couple Quick Pumps Of The Pedal.
