may sound silly, but check that the discs are not in at and angle. also make sure there was copper grease on the rear of the pads. when you changed the pads and put the new ones in did you loosen the master cylinder cap. some calipers push air in the system when pads are replaced, due to the pistons being pushed back further, due to thicker pads being put in place of old ones. hope this helps
lateral runout. your rotors or drums are warped and need to be machined or replaced depending on the thickness. if your slamming the brakes this is normal its your antilock braking system functioning as it should to keep you from sliding.
your brake rotors are warped. You should repalce you brake pads and have the rotors resurfaced if possible, or replaced.
No! Something is wrong.
The first thing I would check or do would be to remove the rotors and check their condition. If they have enough surface left, have them turned to get them true again. If they can't be turned, then replace them with new (which should also be turned or at least checked .The most common cause of pulsating brakes, I have found, are warped rotors. This is usually caused from overheating.
The neighbors I am working on does have an ABS light that is on. So I am assuming yes. But double-check your model. Reason I am working on his is due to the pulsating grabbing the brake pads have on the rotors when applying the brakes. Also another reason the ABS light may be on is due to the warped rotors are fowling what the ABS should be doing.
Rotors out of round - should be resurfaced or replaced
Warpped rotor. rotors are warped have them checked and turned or replaced. they should be turned after every brake change
You should have your rotors checked and possibly turned or replaced as necessary You should have your rotors checked and possibly turned or replaced as necessary
Depends on the kind of pads/rotors you got. It's normal for some compounds to squeak .
The most common cause of this problem is warped brake rotors. Get it replaced soon. Whenever you replace rotors, you should replace the pads. The old pads will have conformed to the shape of the rotors, so braking efficiency and life will be down if you use them with the new rotors.
you have out of round brake rotors, they can be replaced or machined if they are thick enough, the front pads should be replaced or placed on sand paper on a flat suface to remove the glazing so they will seat properly to freshly machined surface
There is no need to spend the money if it doesn't need done. Typically your rotors last longer than your brakes do anyway, so you should be fine for a while.
