Please educate me on this brake problem. 84 GN


Long Time Owner
Did not use the car for 1 month the first time I started it the brake warning light came on and it was due to a hydraulic problem. Bleed the back brakes using a helper and the pumping method, light still on. Gravity bleed the fronts
(helper had to get dinner) fluid kept comming out and topped off master cyl a few times. Light still on. Gravity bleed the backs, had some fluid come out and level dropped a little then fluid stopped comming out. The light went out :confused: .
Have stock hydroboost/master cylinder system.
