I have just installed my brakes, but when I am driving and I apply the brakes, the car shudders. What could be wrong?

• really doubtful the rotors are warped. it would have done the same thing before (if it's the same rotors). If it's notn doubt the new ones are warped

• this would cause a glaze not a shudder and it brake cleaner not oil

• Mine always have, and that is on five different vehicles. If it doesn't go away PROMPTLY though, the problem is elsewhere.
  I've almost always had it stop within the first dozen uses of the brake pedal, the single exception being warped rotors. I did some hefty damage to the front brakes descending Mt Washington ;)

• actually, now that i think about it, mine do to, but not bad. only slightly and only for first few stops.

• JEEEZ IF anything warped rotors will cause a pulsating pedal before anything if the vehicle shudders its a number of things that can be wrong.

• I am just going by my experience here, but if the rotors are warped then the thing would shudder even with the old pads. Been there, done that, bought the rotors. (For most cars I've owned, new rotors were cheaper than getting the old ones turned.)
  If a pad replacement *causes* a shudder that disappears within a day then it is the same thing I have had *NUMEROUS* times; the pads are not yet seated.
  If the shudder does not disappear quickly though, as I said, the problem is elsewhere.
  Of course, there is the possibility that the brakes shuddered slightly before the pad change but just didn't have enough grip to make the shudder very noticeable. I often have a hard time feeling such things in any car that weighs >2800 pounds and/or has too much power-assist... like most modern cars do.
