abs light comes on at 56mph

high guys i have an 06 1,4 clio which i changed the front wheel brgs on last week .Since then the A B S light comes on at 56mph, I have scanned the abs system and it comes up with wheel speed inconsistancy.so i changed the front abs sensors and its exactly the same.So i put the scanner back in and put it on live data on the abs and its showing the nearside front wheel is reading a slower speed then the rest of the wheels . Any body got any ideas
