Q&A

I just had my brakes replaced on all four wheels which included the rotors being turned. I noticed that if I brake real hard on dry pavement that there was a loud noise (kinda like a boing noise) that came from the front which resembled a spring being stretched (the best description I can come up). This noise is more prevalent when I brake on icy roads since it is much easier to lock the wheels when braking in slick situations. The only time it makes this noise is when the brakes lock the front wheels. I do not have any kind of abs brake indicator that comes on the instrument panel and I was told by the mechanic who heard the noise when he was riding with me that this is the abs pump. I'm trying to confirm that this is the problem before I go out and purchase a new/rebuilt/used abs pump. Any help will be appreciated. Thanks.
