rotor not lining up

[a67]

One showing where the pads would contact the rotor face and how much clearance there is between the rotor diameter and the caliper.
I know this may sound stupid but I am wondering if you have an caliper bracket for a 12" rotor and a caliper for a 13" given the diff in thickness between the 12 and 13" rotors and the high amount of clearance you have.
I am reaching I know.

He is using C5 calipers which is why the centering is so critical. They are for a 32mm thick rotor.

C4 HD are 28mm thick.,

C4 standard are 20.5mm thick. Which is what he has.

What Ishmael needs to do is to find out more about the brackets he has. IOW, what are the proper parts to go with them.

He may actually be better off starting over. Figuring out which rotor and caliper will fit inside of the wheels. Then getting a new bracket (in steel !), for that purpose.

They are out of business unfortunately. Noel was helpful but it took me a long time to get this together. Something in there is outside of our control. I have the right hubs per his instructions. Perhaps the brackets are too thick but I doubt it. My spindle is isn't the one with 5/8 bolt boss - its the 1/2" but it looks just like the other two. Perhaps that's it. I thought the fronts were 13 -they were supposed to be and I thought that's what I ordered. Are the 13's a different thickness than the 12's?

was your bracket made to go with the 5/8 bolt boss? the kit I just bought is supposed to go with a 5/8 bolt boss and mine is 1/2 inch also. I'm expecting to do some kind of mod to get it to work, just don't know yet until I get it in. Did you have to do any modification to get it to bolt up properly? Is there anyway you can get a pic up of what the bracket looks like bolted on?

You're not reaching. I just got home, and after placing the mother's day tree in the yard where my wife will see it, I measured the rotor - 12 inches. The kit calls for a 13 rotor. I told the guys at the store to send me rotors for a 95, and I said C4. I should have been very clear. I don't remember Noel offering a kit for a 12' and 13" - only 13". There barely looks to be room for a 13" rotor to spin in therebut I didn't think there was a lot of area of pad/rotor overlap.

Well, some days and three pages later we figure it out and I probably wouldn't have done so without you guys. My wife and neighbour have been asking me how I was ever going to figure this out. It was even suggested that I send it to a mechanic. I told them you guys would help. (crying a little). Thanks guys.

Noel was very helpful here. He sent me 1/2 bolts and adapters that fit right in. I'll take pics of both and post them up. I just have to cancel my spacers order and order some new rotors first. That's done. Here are the photos. If you've got your spindles off, I would have them drilled and tapped. You'll have a stronger bolt. The 1/2 bolt is hard to find. And I had to grind a few threads off the one bolt to get it to fit. Noel would have had to make that spacer up as well.

Glad you got it figured out.

Don't forget that the 13" C4 rotors are directional. Order a R and an L.

Good luck!

Very helpful, thank you Scott. It's a good idea to have it drilled and tapped, I might just have the machine shop do it when I drop the hubs off to get turned.
