Question about 2001 Toyota Sienna
One thing to check before you spring for new rotors - with a torque wrench, set to the proper setting as prescribed by Toyota, loosen and then retorque all your wheel studs. If someone put them on and just tightened them by hand without a measured torque wrench, or used an air gun on them, they could very easily put too much torque, or uneven torque, on the nuts, which would then distort the rotors and create the sensation of warpage that bear001 is talking about. If you don't have a torque wrench, stop by a garage and ask them to torque your lugs for you with the torque wrench (don't let them use an air gun, or you are wasting your time). Most places will do it for you for free, or give the guy a few bucks for the few minutes it'll require for him to do it. You have nothing to lose by trying it, and if your rotors haven't been like this for long, chances are you haven't damaged them. If doing this doesn't fix the problem, you'll have to get new rotors.

TOYOTA SIENNA 2001 SHAKES WHEN I APPLY THE BRAKES,,WHAT IS WRONG WITH THE BRAKES OR TYRES
Posted on Apr 21, 2009
A common problem with brakes are the rotors warping,which causes a vibration when applying the brake pedal.The brake pads,clamp down on the brake rotor,which slows the vehicle,and in the process,both items are subjected to very high temperatures.This is what causes the rotors to warp,which in turn creates the vibration you feel.Best solution is to replace the rotors and pads,with new.The calipers,which hold the brake pads,should be checked by the technician to make sure the piston is working properly,and not leaking.The rubber hoses should also be checked,no cracks or leaks,etc.Good luck.
