Rear brake rotors for '91 SE

[dknighto]

I'm trying to source a replacement rotor for the rear brakes of the SE. I've tried searching the cars that share the same caliper (mostly Renault), but the lotus rotor appears to be larger than these at 275mm. Has anyone successfully replaced this part with something besides the original lotus part?

Well, according to my research, documented on http://home.flash.net/~hess/crystal_princess.htm :

Lemme know what you find.

Dr.Hess,

I saw your research. I checked the rotor diameters for all the Renault cars that use the bendix calipers and they are all quite a bit smaller than 275mm.

I think Lotus may have went with a larger diameter disk for more braking torque. 275 mm is about 10.8 inches. A lot of American cars have 10.8 in discs.

I need to take the rear rotor off and get the hub and height measurements and call a brake place and see if I can get a match. Does anyone have these numbers?

[Dr.Hess]

Darn. According to the parts manual, 89-92 is all the same. I have seen a pdf catalog somewhere from one of the brake manufacturers listing diameters, etc. You might poke around the net looking for Bendix or other remanufacturer's catalogs.

I found the catalog PDF on my drive. Send me an email with your email address and I'll send you a copy back. It has all the dimensions in it. Appears to be originally from some manufacturer in Oz.

You should have it. Let me know if it doesn't get there. Some interesting 275mm solid disks in there: Rolls Royce, Tr3.

If you don't find any let me know.. I've got a nice set of used ones with less than 1000 miles on them I'd like to get out of the shop.

I can't figure out which car the stock ones came out of. Best I could do was get the EBC part number for the rear turbo groove rotors.

I pretty sure the early Jag XJ6 also had 275mm solid rears.
