I broke them in a bit. A couple high speed stops. I'm wondering if I got some grease on the rotor and it squeeks every time the pads hit that spot. I'll leave them for a few more days then I'll inspect em.
That's not the right way to break in pads. The right way is to gently apply the brakes at low speeds to have them seat evenly.
You might want to disassemble them and take a look. Check the rotors too, because new pads won't cure warped or defective rotors.
