Check your calipers. If they don't operate smoothly, it's a very uneven stop you'll get. I just replaced both front calipers on my Elantra, and it stops a lot less violently now.

 

correction from the third post

i have the fuzion vri

 

did you discover what the problem was? I was going to add that if your rear brakes are not working properly, your fronts will get all the pressure, making it MUCH easier to lock them up

 

Not sure how warped rotors would cause this...
But if you are going to get 4 new ones, at least get new ones on ebay, get a drilled/slotted set or something. Don't waste your money getting your OEM rotors turned...

I agree with what Mad machine said...and I have seen on a few tibs where the rear calipers seize up..

 

warped rotors can cause this - especially if they are warped bad.

Make sure when your turn your rotors or get new ones, that you properly torque your lugnut with a torque wrench, or you will have warped rotors again.

 

well i havent had the problem in a while but i took my car up to my dads shop yesterday for 2 new rear tires to match the fronts and when he brought it home he told me he had to put 2 outer tierods on it and a set of pads but i dont remember which wheel he said he put the pads on. he did say there was stiil pad left they were just low

 

When you got the pads changed they could have put an aggress pad composition on instead of a softer material,

Brake pads can have a very noticable effect on how the car stops.
