1996 Lincoln Continental, 105 K miles. 4.6 liter. A couple of weeks ago i noticed driving in the snow that when the traction control kicked in i would hear a loud fast clicking noise coming from engine compartment. It seems that the traction control is working, but i never had this noise before.

Also when i went to brake on snow i got a very loud crunching / clicking noise and my brake pedal vibrated and the front wheels locked up and i had no control over the brakes.

I just had all new OEM rotors, Calipers, and pads replaced on all four wheels. The brakes work perfect in dry weather but i did notice when i do a panic stop i get that crunching / clicking noise and the brakes act like they don't want to stop and fade real bad.

What do you think the problem is ?
