C6Z06 brakes

[raustinss]

Brad I sent you a text message, got the rear brakes thanks so here what I can propose to you..... I've got a full set ( 4 disc's 4 calipers just rebuilt to and fresh blue powder coat pads hoses etc) for a z51 corvette let's trade my set for your zo6 fronts...this will complete my zo6 system, give you new brakes and prevent you from having to replace your wheels. feel free to think it over and either text, email or Pm me.... thanks Ryan

So just trying to get them installed looking at new wheels anyways Vince!! So another reason to get me sooner!! One test fit, as I stated I have a 1" spacer and they clear now, spin pretty freely, but once wheels are tightened up and torqued down cant spin freely in fact can't spin at all!!! I've checked and the caliper is not contacting rim at all and can see gaps all around caliper.....

Loosen and spin again. Is there something I'm missing here..... Please help, really wanted to get WhyTry on the ground and see a sneak preview of how those brakes look back there

What happens if you leave the wheel off and run the lugs up tight to rotor with the wheel off? I'm thinking you need to shim the caliper so that it's centered on the rotor.

[whytry]

That's exactly it!! I did what you suggested and it's contacting on the backside of the rotor.. I don't see any adjustment there. I need to move the caliper closer to the motor (inside) outer pads clear and have 3/8" gap. Inside there is a definite part of caliper touching rotor not just pads I mean. Hands dirty, ideas, suggestions? Got no kids for the day really wanted to get this done

Should I file down the Kore3 bracket? Not sure how else to create some clearance....

get some new wheels buddy....: )

if they clear the caliper they might not clear the outer wheel well or fender. If your gonna run 1" get yourself an adapter spacer. They are much safer.

Yeah. Unless his rims have a huge amount of backspace there's no way they're not going to rub on the outside. That's the problem with the Z06 brakes - wheel choices are extremely limited. I couldn't even get stock Z06 rims to fit on my car.

I wouldn't start modifying the bracket, you need to add shims between the caliper and the bracket to move the caliper back, I would assume that Kore3 sells the shims, you can try hardened washers but they may be to thick. Can you post a picture of the bracket/caliper mounted on the spindle?

Here is 2 pics. Working on more now

On the caliper pic where it's rubbing the rotor I put some silver marker on. It's the 2 circles at the ends of the hockey pucks..

And here it is in the car. See what I mean, there's no room for a spacer... I'm thinking I have to have something installed wrong but it all looks rt... So I'm at a loss...

I don't see anything wrong with the bracket installation or do I see a way to shim the caliper. I see that you are using the stock drum brake hub and I'm wondering if that's the problem. Kore 3's site says that their billet hubs increase the track width by .200" per side which tells me it pushes the rotor out .200" here's the page I found it on KORE3 Industries LLC: On and Off-Road Performance Automotive Components read note 3. I think I would contact Tobin and find out if that is the problem.

[whytry]

Yeah that's what I did. I left Tobin a message. Hoping to hear back today. I called this am

Keep plugging away at it! I know this stuff can get frustrating at times. Sorry I couldn't be more help, good luck.

In the install instructions it shows the bracket has a grooved section on both mounting points and mine doesn't have that... Not sure if generic instructions for all big brake kits or not but a thought none the less

I'm going to try spinning the brackets from left to right side and see if there's something there I could be doing wrong.

Thx for the thoughts!!

Brad, the brackets appear to be installed correctly. The instructions show an earlier generation of bracket that had machined reliefs on both sides and used thicker material, so your brackets are the newest/latest/greatest revision. Next, the KORE3 billet GMSS hubs have the same relative flange offset as the OE Chevy drum hubs, the added .20" track width is due to the difference in rotor hat thickness (~.30") versus the drum hat thickness (~.10"). I've emailed you the Chevy drum hub reference drawing back in June, so I'm going to assume that you really do have the Chevy drum hubs and not something else.

First question...do you have an interference on one side or both? If just one side, then what differs from side to side?

If you put a straight edge across the pad guide pins, are they even? You could shim the pins outward to gain some clearance there, but you're obviously somewhat limited in that regard...I think I saw someone selling pin shims on here or lateral-g not too long ago.
