Default A Mysterious Brake Light - FIXED

I do have a strange brake light problem , not a big deal .So, after I had had my brake master repaired everything seemed to work normal.
However, whenever I do use my brakes a lot red round brake light symbol pops on the dash and I press the VCM button it indicates "PAD" but my pads are too new to be worn out .
No ABS light no other warning lights but a brake light and it only appears when I apply pressue to the brake pedal .
I covered more than 20 kilometers a few mins ago but nothing happened .(I used my brakes too )
So, I presume if a brake pad sensor attached to the pads did came loose ,it would have warned me out all the time is that right ?
I don't wanna shot in the dark ,that's my I would like to know what your recommendations on this .

I still guess at the accumulator ball. It could be a pad sensor, it free to check those out.

Caddy I have a similar recurrent issue on the 92. New pads etc but occasional flashes from the pad warning light. Turned out to be a dickey pad wear sensor.

Ken 2 things, when you say 'ball' for us Brits do you mean the 'sphere'?

And when you supply a set of brake pads, do you mind me asking, would you automatically include a new set of pad wear sensors in the customer's order?

The reason for the question is on 2 occasions when I have ordered a set of pads over here in the EU (not from your good self I may add) they did not arrive with the wear sensors, which needed to be ordered separately?

Boy, this is getting harder lol
I have checked the wires and they were ok . What's happening now is when I press the brake pedal to the floor and when it is about to the point of flooring I hear a ticking / clicking like noise under the ashtray .What's this to do with the braking system I could not figure out lol

When we lift up the center console there are 3 relays you know but of course those are not related to the brake / ABS relays
