2006 Quigley front disc pad contact area on rotor

[longboardguy]

Greetings,
My E350 is a 2006.

I believe my 4wd front axel is a 2004 Ford f350 SD.

Just had my Brake rotors turned and new front and rear pads installed.
I purchased the Hawk LTS pads last year and just had them installed.
I failed to have the old pads saved and the Hawk boxes returned to me so until I can find the receipt I will not have the actual part numbers.
I believe, and according to impeccable records kept by the PO, the pads that were taken off were installed by the PO at the local Ford dealer.

Today I looked at the front rotors through the wheel holes and noticed that the front rotors are showing some surface rust on the area that had been resurface, where the pads do not rub against. The area that rubs on the rotor is only 1 1/16" High. There is still a large area of rotor that had been resurfaced that is unused.
My ancient mind seems to remember more surface area on the rotor being polished with the original pads.
Today I went back to the mechanic and asked about this and was told that this was correct. Nothing was wrong.
I have included 2 pictures taken today through the wheel holes of the front and rear rotors showing the polished and surface rust areas. The pic with the least amount of polish shine is the front rotor.

The rear pad contact area height is 1 7/16"

Can somebody with a similar Quigley front end check their area of "pad polish" on their rotor? Posting a photo would also help.

I will dig to find my receipt for the Hawk pads.

Any help is greatly appreciated.

03 quigley with a 03 f350 axle. No longer quigley rotors, but even when they were, my hawk pads used the entire surface area. IMHO, that is not a “nothing is wrong” scenario. There is most definitely something wrong, at least in the front. The rears look to be using the entire available braking surface.

I'd bring it back to them, That's not normal.
What does the other side of the rotor look like?
If its the same (or worse), check the slide pins and if they're fine (not seized, and have grease) then check Pads to see if they are installed correctly - Otherwise I'd guess it's probably a bad piston.

How many miles do you have since the rotor machining? If less than a 100 or so, don’t worry.
On the first pic, it looks like the rotor wasn’t turned correctly, Ie it’s not at a perfect 90deg angle. Give it time and the pads will eventually bed in making complete contact. The second pic doesn’t look like it’s much to worry about.
When you machine rotors this is kinda normal since the machines used in automotive shops are never setup that accurately, if a real machine shop did it I doubt you’d have this.

You should also look at the back or the rotors as well.

Thanks for the replies.

I found an invoice showing Hawk part number HB538Y.650

I provided the pads to the brake shop, so there is still a chance that I purchased the wrong pads for this f350 4x4 axle.

My first thought was that the pads had not settled in yet. But both sides of the rotors, and both front wheels show the same pattern. There only 10 miles on the new brakes.

The rear pad install looks good. I am sure they are correct.

I made an appointment for tomorrow at 8 am to pull one wheel off the front and check the pad size.

I will report back when I learn something new.

These are the pads I used on 2006 quigley front axle HB302Y.700 LTS

Curious how the wrong pads could fit in the calipers. Hopefully the calipers are the correct ones.

When we bought our van, it had just come out of a brake shop to check on a squeal that would not go away. I had to take it apart and redo their work - turns out they had really botched the assembly. So, these kinds of screwups are not unheard of.

Thank you Shagger. That part number confirmation is what I needed to know.
I just found references to that part number being correct elsewhere on the web.

I bought the wrong part. Apparently the ones I purchased do fit 2004 Ford Excursion, and they are described as "Light duty" pads on the Hawk website.

Thanks for your help.

I really like the Akebono part finder because it has a part number interchange section.

It looks like the Fronts for an 04 F350 SD are HB302P.700. That's the medium-heavy duty pad. HB302Y.700 is the same shape, but in a Light Truck compound.

I think that should be HB539Y.650 which is a rear pad for 03-07 E250.

When I look at that pat number, it’s for an E350. The part # I used HB302Y.700 is for F350.

BTW, Quigley gave me this as the OEM number I should use. 1C3Z-2001-BA
