Brake Problems
Ok so as of lately I have been feeling some vibration when I brake in my brake pedal and in the car overall (passengers can feel it also). So I bought new raybestos rotors and ac delco ceramic pads and I still have the vibration. Could it be the rear brakes? any other thoughts or suggestions?

Moved to the proper section. Please don't post mechancial problems in General Chat.
Collapsed brake line? Sticky or bad caliper? When you did the pads and rotors, did you check for sticking slide pins? Did you re-grease them?

Sorry for posting in the wrong area! I figured this was a general brake question not one necessarily specific to the GXP. Anyway I did re-grease them however I did not check for sticking slide pins or calipers.

No mechanical problems in General Chat. If there'* something wrong with your car, this is where it goes.
If you have a caliper that isn't fully releasing, you'll get that problem. At this point, I'd suggest pulling all 4 calipers and cleaning and regreasing the caliper slide pins. Look for abnormal heat marks on each rotor.
Before actually pulling them though, turn each wheel slowly and feel for any binding. Then have someone press the brakes and do it again after they release the pedal.

are we sure I have slide pins, because the guy I had change my brakes said I didn't have them!
Also thanks for the advise looks like I'll be busy this weekend? also will I be ok driving until this weekend? will this problem do any damage to my new pads or rotors?

I'm going to back out here, because I don't know your caliper setup from experience. I'll defer to those that do.
Yes, you can damage a new rotor driving like that.

something to consider, the GXP wheel use Stick on wheel weights, if this happened all of a sudden ( the vibration that is) you might have lost one of the wheel weights

Well it did happen all of a sudden, but it was a while ago (I figured I just needed new brakes and rotors so I bought them when I had the money) but I will look at the weights also! Thanks!
I just hope the rotors dont tear up before I can look at them!
Also if I lost a wheel weight would I feel the vibration when I was driving and not necessarily applying the brakes?

turned and replaced the fronts....still there.
replaced rear rotors/pads - vibration gone.
this was at 100,000 miles.
