brake warning light when reversing

[gototravel]

Brake warning light is up, prompting brake worn, when reversing. Anybody knows what is about? Recently have both front discs and pads replaced.

Did they fit new sensors? Needs new sensors with new pads.

Have you checked the condition of the rear discs and pads?

Might have this fault in the computer ,so there for it wants clearing. Did it show up on the computer before you had them replaced?

Not having this before replacing pads and discs nor after until recent. Don't know the small Garage has the new sensor in or not, maybe not I gues. Have B service before the brake change, only the front were mentioned not the rear. So, assuming rears are OK. This fault only occurs when reverse, while putting foot on the brake.
