I notice sometimes when I brake it feels like the pads are vibrating on the discs, and the most annoying thing is when I come to a complete stop the brakes make a squealing noise so bad that it sounds like a train coming to a stop? :help Whats going on here? Ive just recently done a disc and pad change. OEM discs, but aftermarket pads. Any Ideas?

Hawk pads? If so I heard they can be loud.

either they forgot to put brake lube on the back of the pads or, you choose a pad that is too aggressive (which creates the noise).

I suspect the pads. He said they're a fairly aggresive compound. Better for track use.

There is your explanation probably...

Too aggressive of a pad on the street (where they can't get up to temp) can tear up your rotors. Do you remember the brand/model of pad that was put on the car?
