i did the pbr brake upgrade on my 94. while bleeding the brakes the firm ride light started to come on with every push of the brake pedal, stay on for approx 3 seconds then go out. i can hear the actuators working. the light acts normal when i put the system in firm. i have a self bleeder and bled mostly with the engine off. i did start it and bleed a few strokes of the pedal. has anybody seen this before?
