Car vibrates while braking...
Well mine does this too. And no it is not normal. I had a Dakota and mine did this, well it got progressively worse, because the damage to my rotors was progressive. Wat you describe sounds like what I have in my Trans Am. Warped rotors, if you don't change them out or at lest get them turned and serviced, you'll be in deep poopy. After the pads eat away all the rotor material and get down to the inner vents/ ribbing, it sends to eat the pads to bits, and then your calipers. At this point it is not a serious problem if it isn't violent shaking, but just subtle, but it can be very damaging and very expensive. I recommend replacing the rotors for some more heavy duty ones. You can by simple replacements, but personally I would beef it up. You can get some Baer Eradispeeds, or Powerslots, both good brands. Or go really well and get C5 rotors from LGMotorsports, which I plan to get. It has performance C5 rotors, and a bracket that extends out your existing calipers to reach around the new larger C5 rotors. It uses the stock calipers and for a comfortable non squeeky ride you may still use stock pads. It all depends on how much money you want to spend.
As noted above, you probably have warped rotors - its not uncommon. The correct/thorough way to check is to measure the lateral runout on your rotors while they're mounted on the vehicle. My guess (emphasis on GUESS), though, is that if you just replace the front rotors with some Brembo blanks (cough...cough... http://www.tirerack.com/brakes/resul...emium&x=83&y=8 ) you'll see the problem go away.

Warranty covered my warp rotors 3 or 4 times. Stock rotors are garbage and driving easy won't stop you from warping them. I ended up converting to Corvette brakes in the front to solve it.

Wouldn't count on the warranty especially if you have exceeded factory warranty. Many aftermarket warranties will only cover drive train which usually means motor and trans. But hope yours will cover brakes.

it's the rotors. they are warped... My '99Z had new GM rotors installed when I bought it (the second set at 30K miles) ... it took only 6 months and they warped.... brake parts are considered 'normal wear' and are usually not covered by warranty...
I bought the $40 rotors at AutoZone and new pads - these are installed for 40K miles with no problems whatsoever.... it's not always only the most expensive solution that works best... good luck

Just do what I did. Keep the stock parts and if something breaks, put the stockers back on and then take it in.
