Ok watched your vids, thx so much for the sharing! I just installed a new accumulator ball & pressure switch. Of Cours de pressurizing the system properly. I re-pressurized the ball turn the ignition on with new fresh fluid going into it and check for leaks there are no leaks anywhere also before whenever I hit the brakes the brake light would come on and if I slammed on the brakes hard it would feel like I’m stepping on a brick it would not break right away but then the pedal will go down. Today the next day I took your advice turn ignition on I press the brake pedal three times the motor ran for six seconds then shut off and I waited and waited and waited for more than 33 minutes the motor never came on again and I mean I stood there and waited honestly.
