Brake Install Problem
This pic is after bedding in HPS brake pads on new rotors. I purchased the brake calipers from a forum member. The 3/4 inch ring on the rotor around the hat does not look right, I do not think the pad is coming in contact with the rotor. Any opinions?

I would think you could check for pad contact in a number of easy ways. Perhaps a chalk line on the rotor as a tattle tale, a paper inserted etc., if the width of the pad cannot now be measured.
I have so little to add, I can almost hear all the eye rolling out there, and that makes no sound at all, that's how weak is my obvious suggestion . Is it still called a blabber mouth if you type it out?

You know the pads are contacting in the outer area. Put a straight edge on the pads to make sure they have a consistent thickness.
Remove the wheels are turn the steering wheel so you can get a clear look at everything.
What does the other side look like?

Debris on the pad is my guess. Is it scoring or a mark? I doubt your calipers are bent. Does make noise while driving? While spinning the wheel by hand? Did you rice the rotor with brake cleaner? Did you touch the pad surface with greasy fingers?

I replaced all of the brakes and rotors. This problem seems to be isolated to the front left brake.
I do not feel any vibration or hear any unusual noise.

The the inner rotor surface looks okay.

The gray area at the bottom of the pad is not contacting the rotor. When using a staight edge there is a very slight gap at this area. The lighter portion of the pad is what is making contact with the rotor.
I also found the lower caliper slide pin bolt not completely seated against the caliper bracket. The caliper pin bolts were new factory, it looked like the bolt received a double coat of thread lock making it hard to turn as it was torqued 23 ft lbs. I cleaned and removed the factory applied thread lock and reassembled using Blue Loctite.

It's raining now. I'll take it for a test drive tomorrow.

I think the pads will wear in. I wouldn't be concerned if it's not scoring the metal surface of the rotor.

Someone correct me if I'm wrong... That's a red loctite item, based on temp and stress I think. Loctite has a decision tree on their website to determine which one. Make sure those bolts are in and torqued. No bueno if one backs out on you.

Concerning the bow in the Hawk HPS brake pad: I 'll see if I can contact someone at Hawk Performance.
