Hi there

I had my rear breakes and a few front suspension parts replaced, and now i got a Antiblock brake light turning on when ive been driving for a few minutes.
Ive noticed that when i hold my breake pedal, and turn on the car. Im getting that caracteristic ABS engage sound, like a ratteling for ½ to 1 second.
Ive got what sounds like a faulty rear wheel brearing, but it could be a bushing that needs replacement.

Any ideas to whats wrong?

Thanks
Kim
