Help Identify My Brakes - ZR-1 Net Registry Forums

emmvette · 08-12-2013

As the title states, I am looking for a little help identifying the brakes on my car. The calipers are easy since they say "Brembo" on them. How about the two piece rotors? I can not find a single identifying mark on them. The rotor hat and the mounting pieces are the same light blue color and are aluminum. Does anybody recognize these?

I would estimate them to be from around 1995-1998.

Below are pics of the rotor and calipers, front and back of the rotor, and last the mounts.

Any ideas?

Those are Brembo rotors. Looks like a custom adapter for the rear caliper mount.

Looks just like my Brembo Indy rear brakes!

Did a little snooping and found this fellow who is a source for Guido who built
Brembo system upgrades for ZR-1s in the late 1990s:

I doubt TF was around then but he might be some help. Your real concern is where to
get replacement pads and rotors - some of this stuff was 993 Porsche.

The other possible is Callaway who also did conversions in those years too.

Hope this helps,
Glenn

Hey Eric - who did you buy that car from? Does it have a roll cage and a differential oil cooler?

So what is wrong with them?
Mine have always squeaked; even when new.

No problems at this point... The wheel was loose so I inspected for a bad wheel bearing and found upon disassembly that one or two of the fasteners holding the hat to the rotor were loosening. Could have been trouble, but I caught it early.

I may revisit this and put some thread-lock on all four corners. Any thoughts on this? I know they get hot, so I would need to investigate the temp rating of the thread-lock.

These may be impossible to find, or at least very expensive to replace the rotors, so its worth preventative maintenance on my part.

No experience with Brembo but I have ruined numerous sets of the Wilwood 2-piece rotors and they still have the rings. You can get them from HRP World just take some measurements and you should be good. If in question call them they are very knowledgeable.

BTW it is not expensive I think somewhere around 300 for a pair.

Almost forgot don't use the thread locker just safety wire them.

Thanks for the link, I appreciate the knowledge share! I'm not sure what you mean by "safely wire them". The fasteners are a female hex head cap screw, so they just get tightened with allen wrench or a male allen socket.

Those look like extra long wheel studs. Is the hat very thick?
I wonder if the brake and emergency brake caliper adapter (backing plate)
pushes out the wheel offset?
And emm, what wheels do you use?
