Brake Shudder on 4.6

[2ez24get]

When braking the car would shudder. Car has 38k miles. The right front rotor had hundreds of dark spots on both sides and several groves in the front of the rotor. Both side pads looked good with plenty of life left. I just finished replacing the front pads and turned the rotors on my 4.6. The shudder is now gone. I wonder if others are having these kind of issues with front brakes on their 4.6?

Thanks.

I only have 900 miles and I noticed from day one that when I first apply the brakes....the rear ones are suppose to brake first...a shudder sound. Sounds like the rotors or something is out of round. Haven't noticed it on the front brakes. Will be taking it in for a service to have it checked out.

The dark spots on a rotor usually are hot spots and can be caused by an oil or oily chemical getting on the rotor. Sometimes the spot or streak will have a dark blue tint.
