ABS/SERV dash indicators

[philobedo]

Sorry if this is an old one but I am new to the forum
If ignition turned on all dash test lights extinguish successfully but when driving approx 1 mile the abs and serv light come on and stay on and the abs stops working.Both the sensors on the front wheels have been changed but the problem still happens, (clio 1.4 petrol 04 reg)

Brake switch? Are the rear brake lights working?

How long ago were they changed as one may well have come loose since or even split causing a loose connection. Also check to see if your brake lights come on while breaking as if there is a bit of delay between you slowing down and brake lights coming on then try adjusting the switch by the brake pedal.
