Rotors get hot then the car shakes

I have found that when I am doing some spirited driving and my rotors get hot car will shake when I apply the brakes. After the rotors cool down and I get back in the car to drive it , Feels okay. My question is if this because my rotors are warped?

During spirited driving there has to be a proper balance .. Being in the correct gear , and high rpm's for engine braking entering into the turns . You will find that entering turns within lower gears and higher rpm's the car will corner nicer and exit out the turns better while being in the power band . Other wise you will cook the brakes by using them too much .

Rotors get hot then the car shakes

I may have Miss used the term spirited. Allow me to rephrase when I'm driving the car a little harder then normal driving and I apply the brakes a little harder than usual after a few times of doing this and the rotors get some heat to them they begin to shake pretty violently during braking. After rotors cool all is well. Would adding heat to an already warped rotor cause it to shake more then a rotor that is cool?

I would would say yes ,, once they are overheated and warp thier toast .. Do you feel it in the steering wheel also when you step on the brake ?

If they only shake after heating up, then I would say it's your rotors. If it happens even when cold, then you might have bad control arm bushings.

Not uncommon at all to have your symptoms with rotors. Some issues with the castings will cause this and also a vehicle that sits in one place for several wet n dry cycles like multiple rainstorms or parked where lawn sprinkler wets brakes daily can rust pads to rotors and the one spot oxidation that goes subsurface can make that one spot have different properties. The reason you see deli platter covers or other wheel covers on new vehicle on transporters is for storage at ports where the cyclic wetting w/o being moved can happen.

Regardless of cause you need rotors. If it is felt w/o shaking steering wheel that usually means rears and vibes in steering wheel would mean fronts.
The bolts and bushings need to be lubricates to assure the calipers can freely move so pad retraction gets pads clear of rotors as that can also lead to rotor problems but usually not temp dependent ones.

Do I have to buy bmw rotors or can I get away with a different brand? Is there really a big difference or is BMW just proud of their name?
