Two piece brake rotor replacement.
« on: June 28, 2012, 02:02:11 AM »
I need to replace the original two piece rotors on my '68 that uses the four piston calipers.

Does anyone know if anyone is making just the rotor section of the two piece originaI?.......................... I would like to find just the rotor part and keep the original hub. In another post I had put up, "tmodel66" had responeded the he found these on Amazon.com (Bendix part # PRT1213) but is using them on a "69. Amazon asks for your car info to make sure a part fits your car. It will say "yes" for a '69 but "no" for a '68. Maybe they work with the '69 single piston caliper but not the '68 four piston calipers.

I read a lot of old posts on this but most are pretty dated now. I know you can get the entire two piece (rotor and hub) in reproduction now. Just wondering about the rotor part by itself.

                   Thanks....Dave

From what I found on the interweb the Bendix part # PRT1213 is a one piece rotor. I have not seen the repop two piece rotors sold separately yet.

You're not alone in this search.  I asked a couple vendors at spring Carlisle and Right Stuff at the Camaro Nationals and they said no, the rotor alone is not available.  You'd think they would contact the supplier and get this going.  Maybe we need to call the factory in China?  And I just sent a pair of rotors back to Summit, same issue, one piece dealios.

That's for both the rotor and the hub. No one is selling just the rotor.

Ed,
 Do you know if the Rick's rotors fit the factory hubs?

No, I haven't had any experience with the repop rotors so I can't say.

Sorry

HUH???  No one is selling JUST the rotor???  You can purchase the replacement rotor without the hub.  It then will become a one piece unit.  Not sure what you are asking here?

The original rotors on these Camaros were a 2 piece design. The aftermarket had 1 piece to replace them when they wore out. They are now being offered as a 2 piece design again but some would rather keep as much of the original car as possible so the wants just the rotor minus the hub....Joe

Here's a link to rotors for '68.

Daniel, the picture in YOUR LINK is VERY misleading. First, it shows a 4 lug rotor which wasn't used on the Camaro. Second it shows only the hub, which isn't correct for that part number. The 5514 (in various part number extensions like BR5514, 5514AX, etc...) is a 1969 and later replacement "one piece" hub and rotor assembly that fits the single piston calipers. The 67-68 Camaro uses a smaller hub because of the 4 piston caliper design and the 5514 won't fit.

However, the 5100, which is also a "one piece" hub and rotor assembly USUALLY fits the 67-68 Camaro, but because of machining tolorances, not always. I'm running a set of 5100's on my 68 right now and you can see how close the hub comes to rubbing against the caliper (see below). I HAVE had to take new ones back once or twice over the years to exchange them for different ones because one might rub while another one wouldn't. China (where just about EVERYTHING is made now), doesn't have as stringent tolorances as one would hope!

Anyway, the "correct" 2 piece hub and rotor is only available as an assembly and you can't buy just the rotor. At least not right now!

Joe, isnt that what I said?  .....  Perhaps he is asking how the hub is on the 1 piece unit as Ed pointed out with clearance???

Ed I don't know how a '68 fastens to the spindle but those 4 holes are not the lug pattern but for the 4 bolts that hold the rotor to the hub from the back side of the spindle. The spindle has the lug studs in it not this part of the rotor.

Sorry for my bad terminology Daniel. I said "lugs" but didn't mean wheel lugs. What I actually meant were the rivets (or bolts) that attach the rotor to the hub which, for the Camaro, was 5 (see the top picture below for one of my original rotors less the hub).

And some trivia for you guys, original FACTORY hub and rotor assemblies had the rotor rivited to the hub like the Corvette. Later service replacements (like the one in the bottom picture) had the rotors bolted to the hubs.
