Right just fitted new wheel hub bearing assembly, fairly straight forward. Took for drive abs light went out after the magic 8kmh. Took it on A14 yesterday cruising at a good speed touched the brake pedal and abs kicked in very scary as no feel to brake pedal took foot of pedal re-applied and all was OK. Out today and the same thing, but no warning lights coming on. The new unit came with speed sensor fitted. Any suggestions?
