I have a Hot rod project where i am using C4 Brake Calipers Rotors ect.
problem is that I have the Rebuilt Calipers on the Rear and the caliper Mountinng Brackets.
I have a Hot rod project where i am using C4 Brake Calipers Rotors ect.

Problem is that when Assembled the Bracket crashes into the Rotor.
What Do I have wrong here?
Only on the Rear.
Thanks
Hi
The bracket should bolt onto the 88-96 hub adapter, clearing the rotor.
Do you have the correct 88-96 diff and hub assembly? the brackets the callipers bolt onto should look like the one on the link below it bolts onto the knuckle. You may have a different calliper mounting point, not aligning it to center of disc. Or the hub bearing is not the right one and is it mounted correctly?
Slip a rotor off of one side of your project and post a snapshot of what's there. If you've bought new rotors for the project post brand and part # of them.
This is supposed to be off of a 1988. Same car front end and no issues.
Rotors were evolution rotors. Power Stop K1518 Front and Rear Z23 Evolution Brake Kit with Drilled/Slotted Rotors and Ceramic Brake Pads
The mounting bracket on the left should be cast 10052211 and be facing you I believe.
Are you attempting to use the bracket lying on the ground somewhere? Looks like maybe mounting adapter bracket of some sort. There's nothing that stands out as 'obviously wrong' at first glance.
I believe the caliper mounting bracket has a thicker dimension and a thinner dimension. Thicker towards the knuckle, thinner towards the disc.
You have the same issue both sides?
What is the casting information off of the 'abutment brackets' - any that you can read might be helpful. Both side should be identical I'm quite sure. I don't have any loose to compare but if you search this # 10112652 on eBay you should find some to compare with. Yours look 'odd'.
Check rotors
84 to 87 = 11.5" od x 2.484 high
88 up - 12" od x 1.986 high
Rotor on hub retain with a wheel nut. Try to fit an abutment bracket without the caliper installed. If no go you have the wrong year rear end, incorrect rotor for that year rear end or incorrect abutment bracket.
If you have compatible parts:
Top pic: Appears that the caliper is not positioned correctly in the abutment bracket it is either to far outboard or the caliper piston is out. The inside pad ( friction surface) should be inline with the inside of the abutment bracket = the outside pad will locate inside of the outer shell of the bracket (circled in red) allowing the assembly to drop over the rotor.
Thanks for the Reply's.
Attached are pictures of the mounting Brackets.
This is a Flat Out engineering on a 1955 Chevy Truck.
This is a Corvette specific problem. nothing to do with FOE.
Only thing I can think is they sent me the wrong Brackets, or This is not a 1988 and is earlier?
There's nothing wrong with the aluminum caliper mounting brackets so long as you have left and right.
Your suspension units knuckle, spindles, rods etc came assembled for each side or you put components together?
If the 1st snapshot in post #8 is the RH side I believe the caliper mounting bracket is mounted correctly. I just took a "quick" glance at an assembly I have here stuffed into a corner and I can't see the casting information. The left side seems to be facing the outside. They're in a corner and hard to put hands on, I'm looking at them from maybe 6'. I can look closer tomorrow.
Last pic post 8: Are you showing that the rotor is cocked on the hub when assembled?
If so loosen the bolts abutment bracket to the upright, secure the rotor to the hub, measure the space abutment bracket to upright, have spacers machined & get longer bolts.
Done deal using what you have.
BTW Mcmaster Carr has numerous spacers & bolts maybe something off the shelf will fit.
I mentioned back in #5 that your abutment brackets looked 'odd' - it's difficult to tell from your snapshots but here's a used left rear and maybe you can visually compare yours to this.
If your knuckle casting, the aluminum bracket castings match (I'm assuming they do). I would have thought you bought suspensions already assembled. Your issue is either assembly or wrong abutments. The D413 pad is correct, the rotor seems correct (has correct min thickness reference).
I have no idea where you're at but if there were a Cardone reseller close maybe you buy a 14-1181 abutment to compare to yours. The problem is Cardone is known for 'misfits' and just wrong parts.
The source you used if the eBay 'seller' matches real-life retail seller is known for parts issues I believe.
Hi
I recommend bracing the rear coilover mount, have seen some break the hub bracket with coilovers. I have put a brace bracket from the lower coilover bolt to the dogbone trailing arm mounting bolts to support the extra stresses.
Have a look at post 24 on link below... and Post 34 for fix like i have done to my c4
