So i get in my car turn her on and let it warm for a couple minutes as usual. i get out a few blocks everythings fine. i get onto the highway to get to the mall and when i slow down for the exit i feel my brake pedal pulsing alot. very noticeable under harder braking. im assuming its warped rotors but im not sure thats why im posting. haha. anyway if it is this will the dealer take car of it under warranty? any help is great thanks.

.357

if it doesn't solve the problem your rotors are warped.

he thinks that my rear rotors are warped because i didnt feel any shaking in the steering wheel.

Assuming your car doesn't drift left or right too much, you can take it up to 60-70 mph and put VERY light pressure on the brake pedal while releasing your grip from the steering wheel. You may notice it then.

What .357 is referring to is a brake pulsation caused by pad material transfer, typically the "glue" that holds the brake pad together. It can sometimes build up at a certain point on the rotor, causing a thickness variation. Getting your brakes very hot can melt the material and distribute it more evenly around the rotor. If you try the above technique, make sure to drive at highway speed without braking for a bit to allow your brakes to cool, so you won't transfer any more material when you come to a complete stop.

The same thing could, of course, happen to your rear brakes.

others. some more directly . . .

have you eyeballed the rotors? sometimes it's painfully visible (sometimes in the shape of a brake pad).

if the hard braking doesn't appeal to you, you could also try some garnet paper on your rotors to try and remove any deposits.

bedding.

Try re bedding the brakes. Do a search, you should be able to find it.
