2011 Chevy Impala: metric or SAE?

[Elkins45]

I’m probably going to have to pack up my tools to replace pads and rotors on a relative’s 2011 Impala. He’s a couple of hours away so no running home for tools. Do any of you happen to know if they used SAE or metric bolts? No sense taking a whole bunch of wrenches and sockets I won’t need.

Looks like metric 14/15mm

Per the video below, you will need 19mm for lug nuts, 13mm & 15mm for the caliper/bracket and a T30 Torx bit for the rotor set screws.

Thanks.

Make sure you have a couple lengths of breaker bar to undo the caliper and bracket nuts and maybe a BFH.

I think these are typically metric. But you won't know the sizes until you check as they can vary for a variety of reasons.
