the mopar(52128247aa) rotors cost at the dealer about 300euros
the brembo rotors(09.8864.10) cost about 150euros
and they are better.

Turning rotors is only a temp solution that can cause worse damage then what is already done,just pony up the money for new rotors.Is saving a few bucks really worth your life or your families?Is it possible to have your brake rotors turned down instead of replacing them?
This week I plan to pop my brake rotors off and having a local garage or brake shop to turn them down for me providing there's enough material left.

Yes it does,the diminished ability to disapate heat severly reduces braking perfgormance.Plus if turned real close to the min thickness can/will over extend the pistons in the caliphers after time and leaks will occur which will lead to total loss if braking ability.When you get the rotors turned, it doesn't diminish your braking power.
Turning a rotor a few thousands takes more material then you think,you should see the pile of metal left after turning a rotor.Many of the newer vehicles on the road have a very limited tolerance for the rotors,ussually as soon as the pads need to be replaced the rotors are also at/below specs and can not be turned(Toyota to name one).I think you guys are splitting hairs here.
Unless you've turned them far below mfg spec, you're not going to overextend pistons
The few thousandths they shave off to smooth them out is NOT going to significantly affect the heat dissipation unless you're driving a F1 car or something. For most people driving their car to work and the store, the brakes will function just fine having them turned.
In theory, I agree with all arguments made against turning them. I just think that for a good 95% of people on the road, turning them down is just fine. There is a large difference between theory and reality.
You can disagree but it still does not change the fact that it does decrease braking performance,not so much in a 1970 Caddy but does more so in newer vehicles that are using tighter tolerances to save cost.I still disagree that a few thousandths on a normally worn rotor will cause significant changes in braking through decreased heat dissipation.
Sure like to now where your getting your rotors from,except for my PowerSlots I have never paid more then $40 per rotor for the highest quality rotors from Napa or Carquest.Now a pickup or high performance car you got to expect to pay more for the rotors since they are larger then normal vehicles,which makes it more important to not turn the rotors.I used to just replace them, but with the cost going up like mad, it's worth it to turn them once.
You should see the rotors poeple want me to turn(about 80% of the cars for brakes services),I'm suprised there car even stopped.I'd counter that if you're seeing a lot of overextended caliper pistons, a larger culprit is running the brake pads down to the backing as I change them out while they still have a good 1/16" or more. I heartily disagree that the few thousands taken off from a proper turning is to blame.
That pedal "pulse" is the result from your rotors being turned,less metal = less ability to disapate heat resulting in premature warping and quicker brake fade.Just remember that after turning a rotor it still must be thicker then the min thickness,if not you need to get a new rotor.You also must always replace rotors as a pair,front pair or rear pair.Thats why there is a minimun thickness to be measured. I agree with Atrus, turn them once IF they are turnable. Now that I see the results of mine being turned once, I am getting new rotors in the near future. The pulse inthe pedal is driving me nuts.
And yes if you turn a rotor to the min thickness and wear out a set of pads you do run the chance of over-extending the calipher piston seals,have seen it many,many times over the last 3 months at my job.
