Brake warning light stays on
#1
Why is it staying on? I've installed A body discs up front and a reproduction booster assembly for power brakes. The pedal seems firm and the car stops in the lot. Once in a while when the pedal is pushed to the floor firmly the light will go off (car running). I bled all four corners again today and cracked the lines at the master while holding the pedal down. Bench bled the master before install of course too. Distribution block is a new repro piece with new switch. The parking brake pedal is depressing the switch.
Am I missing something?? Something else to check?

Yes! There is a pressure switch at the distribution block usually mounted on drivers side between firewall and steering box on the rail.
Probably unplugged or wire cut.
i have a picture if you need it.

The wire and harness are brand new. Gonna try pushing the plug on harder just to be sure. Everything in the system is brand new.

I like to put a dab of dielectric grease on it.
Objects quickly DISAPPEAR in the rearview mirror and PLEASE stay seated until the ride comes to a complete stop!!

Some times those switches get stuck in the closed position. Try pushing on the brake pedal super hard (with both feet) youll here a pop and the light will go out. If not you might have to replace it.
If a man speaks while in his garage and his wife does not hear it, is he still wrong?

Even a brand new one? Could pushrod adjustment have anything to do with it? I wouldn't think so but just exhausting every possibility.
