Anything out of the ordinary when changing pads/rotors on the 4-piston (GT non-PP) brakes? I've done brakes on several other cars and didn't see any how-to for this one yet. I feel it should be pretty straightforward but figured I'd confirm first before getting into it.

Fronts are very straight forward.
Rears pistons screw in rather than push in.

Sounds the same as the S197. I did the loan a tool thing from Advance or AutoZone when I changed mine on the 08. The tool made it very simple.

What the Chef said plus if you never added any fluid leave the reservoir cap in place
Is that to keep air from getting into the master cylinder?

I don’t have any reasoning other than there is no need to remove it like we did in the old muscle car days. If you haven’t added any or lost any then the fluid will just fill the reservoir back up

Pushing the piston back without opening the bleeder screw is just asking for trouble. I know people do it all the time but you do risk the ABS unit and the master cylinder seals.

The way I understand it is, there’s air at the top of the reservoir bottle, the air needs to go somewhere when pushing the pistons back in and the fluid rises in the bottle. Hence taking the cap off.
