How do u know rotors need replacing

If it's been more than 2-3 yrs., the fluid could be so saturated with water that it's boiling and not fully transmitting your pedal action to the caliper pistons.

Also, can't rule out the Master Cylinder either.

Minimum pad wear s/b 2mm (0.08"). You get two sets of brake pads before requiring a rotor change. OEM pads cost me $120 for both axles + $22 for new brake fluid.

How do you know that the rotors need replacing. Do you measure runout and/or is there a minimum thickness to the rotor?

You get two sets of pads use out of the rotors.

You should measure minimums.

Using a mic, measure thickness.

Front: 22.6mm (0.89")

Rear: 18.6mm (0.73")

Disc machining limit:

Front: 22.0mm (0.87")

Rear: 18.0mm (0.71")

I purchased that set from Paragon, and they are just right for the driving I do (street + occasional autocross).

I actually don't know whats up with the brakes. I haven't got a notification from the dash yet, the brakes just seem a little numb and don't seem to stop as well as I would have thought. I'm not sure if thats normal(still new to sports cars), but yeah, I'm a smidge worried.

Thanks. Its nice to hear from someone who has bought a set from Paragon. I'll feel better now when I order and install their set.

I also got my replacement OEM (Textar/Pagid) pads from Paragon. Best price, easy service.
