After changing the passenger front wheel hub, due to a faulty abs sensor, the car made a real loud squeeking/howling sound from the brakes. So I whipped the wheel off and took half the caliper off, cleaned everything and put them back. The squeeking sound has now gone but there is still a light grinding sound I can hear. This sound can be heard when the car is plodding along normally and I drive past cars. It sounds pretty metallic. The hub was brand new but it's coming from the side that was changed :S. Could it be fitted badly or could this new hub be at fault?? It's a 5 stud 280mm front setup. Any help would be much appreciated. The pads and discs are both fine as they were changed to mintex pads and discs not so long ago. As I said, problem started after changing the hub. Do they need time to 'bed in'?? Any help is much appreciated. Thanks for reading!
