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?
 
Right taken speed sensor out and there are some spacers that have been damaged so I gues the gap may not be perfect, how critical is the gap? The o ring also looks slightly damaged but nothing serious.
 
very critical,they really need to sit in properly damaged o ring might not let them seat far enough down
 
Just fitted old speed sensor with old rubber washer, went for test drive now what is strange sub 60mph all is normal. However cruise at 70 for few hundred yards put foot on break and its fairly hard and can feel abs let foot of and reapply brake and all is well? Is it just coincidence that I changed hub?
 
ive had similar with faulty sensors with brakes been applied when you get aboth certain speed all run off same sensor abs tc and hd fitted another sensor all okay ,funnily enough first new was genuine second britpart
