Brake sensor light

[Dangermouse]

Hello guys
I have replaced front brake and rear brake discs pads and new sensor front and rear. All was well and the light re set. A few weeks later I had to replace my battery. Once the new battery was fitted the brake pad warning light came back on within a few miles. I have had it re set at the garage using computer and also tried lots using the door open for 30 second re set. The light went off on all occasions but after a few hundred yards the brake pad warning light comes back on. Has anyone had any experience of this fault as I am going to try a new sensor if it persists.
Thank you

Solved it guys
I took both sensors back out and after a quick visual the front one had broken after only a few weeks.
I guess it happens that they can break for no reason
New one in and light re set car is back to it’s brilliant best
Most reliable car I have ever had and in 16 years it’s never put a foot wrong.
I must say the sensors are incredibly easy to replace.
