Has anyone noticed the minimum weight for the left front rotor is slightly more than the right front minimum weight?
Does anyone know why this is? Is a more minimum weight required To help compensate for the driver and left front being heavier or, is each rotor a different weight when new therefore the minimum weight varies from rotor to rotor?
If I understand what wstab is saying, each one starts out at a slightly different weight, and I imagine the min weight is the original weight less whatever wear factor they allow. So let's say 500g is the max weight loss over it's life.
A rotor that starts out a 5750g will have a min weight of 5250g, whereas one that started out at 5813g will have a minimum of 5313g. So each is different because they start out different. That's how I understand it anyway, but it's only my conjecture.
The binder that hold all the "stuff" together out gases with heat over time.
Once the loss of the material (binder) that keeps the rotor from fracturing reaches a certain level the CCB rotor is considered structurally unsound and should be replaced. I have used them below the minimum weight on my track car and have not had any problems. Fronts are the ones that generate the most heat. I have not had any rears that are below the minimum weight yet.
For anyone curious the wear allowance is about 100 grams. So make sure you clean the brake dust off when you check weights! I had 7 grams of dust on mine, every little bit counts when you only have 100 to work with

Thank you! I was looking for how much wear you can get before hitting the minimum allowance
