G37S-K52

Hey Everyone,

Upgraded my G37S rotors to cross drilled/slotted premium rotors from brakeperformance.com and also purchased Hawk HPS 5.0 pads to go with them. Initially after install we felt some drag on the rear rotors and we adjusted the parking adjustment screw all the way loose which did not help. Took everything apart and took greater care to clean and lube/grease pads, shims, pins and so forth. Used CRC caliper grease (comes with a brush) to lube the small pins that hold the pads on one side (where the brake pads slide into). The drag went away but still getting a loud squeal from a single caliper (rear driver side). Performed the bedding process and drove around for about 70 miles and problem continues.

There are two bolts behind the caliper that hold it in place, during install my dad accidentally over torqued the bolt and we had a hell of a time getting it back out, had to use PB blaster and a bar for extra leverage to get it out. While we never hit the caliper directly for any reason and just the wrench/bar we were using for leverage to get the bolt to loosen is there a chance the vibrations damaged the caliper on the inside? Can't think of any other solutions.

I may swap the rear rotors and pads back to OEM to see if the caliper continues making noise. Any other suggestions are appreciated.

Did you re install the brake pad clips/shims
