2005 Pontiac Gto

We put a couple of nuts on the wheel studs and tightened a bit to ensure the rotor/hat assembly was flat on the hub. We then temporarily installed the six-piston brake caliper. Note that there is a left- and a right-side caliper: when correctly installed, the caliper's largest piston will face forward (so that it is the last one to grab the rotor as it spins; orientation arrows are stamped on the caliper as well). Wilwood says this differential-bore piston configuration provides more even pad pressure, extending pad life and improving stopping performance.
