Hi, Just as the disco comes to a stop (1-2 mph) the abs pump starts (vibration on pedal) I suspect a sensor or sensor plug. the disco is on tarmac and moving in a straight forward direction. I thought the abs was inhibited from activating under a certain speed. so could it be something else. Thanks

Hi, it can be ABS or EBD misbehaviour due to a signal missbalance, make sure that the tyre pressures are even per axle and as close as possible to the factory recommended ones cos the system was calibrated to work 100% within those parameters including tyre dimensions. It happens also when different brand sensors are mixed. It's not a faulty one cos if it was you should have got the 3 amigos.
Another issue can be if the calipers are not braking the wheels with the same power so one will stop faster than the other

Hi, Sierrafery, I suspect the latter (Brake in balance) as nothing has been changed in the last 2 years, this fault has just started today. Brake discs and pads were done 2 years ago but we do a very low milage and they look fine, but could probably do with a quick clean-up slides etc. could be a sticky piston as we have that before as well.
Here's a link about false abs activation which usually happens at low speed.
