My 991,2 GTS DIY buddy recently installed GiroDisc front rotors. Our first attempt was backasswards, the second time, we got it right well almost. I don't realize we had installed the rotors incorrectly until I got home...a 20 mile drive. I returned to the scene of the crime n a week, and we outlined the necessary steps to correct the mistake, incorporating a screw up that could have been catastrophic. Here was the process:
Take of the left front wheel and remove the caliper and hang t out of the way, a necessary step, prior to installing brake discs,
Now, remove the right front wheel and hang the caliper, NOTING, there must be a caliper expander set within the left front wheel. Why? Obvious now....you must secure the left front wheel to brake it loose. If you have the right front caliper hanging and there is no caliper expander holding the brake discs in place, you'll pop the disc(s) out, and possible dislodge a brake piston(s) as well. As the the guy responsible for pumping the brake to secure the right front caliper, I confess to doing 2 pumps then realize that something was terribly wrong. We then installed the caliper expander to secure the pads.
Now, break the right front caliper loose and remove the GiroDisc that was installed backward, install the correct one. Repeat on the left side
