5 lug rear disc brake rotors, just the rotors - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Mandic · 11-21-2012, 08:29 PM

Does anyone know of a good source for 5 lug rear disc brake rotors? I already converted my front end and am looking to convert the rear. However instead of buying a disc brake kit I have individual components I already had on the shelf. Namely a set of weld on disc brackets, a pair of calipers, and lines. However I am having a hard time locating a source for a pair of slip on 5x5" 5 lug rotors. All of the front GMs I find have the hub assembly integrated and don't appear to be able to separate them. The parts I have are from an old 4x4 project where we could separate the hub and rotor to use it.

I really don't care to spend a few hundred bucks to buy someones kit when I have almost all of the parts already. I mean these companies have to be selling replacement rotors for their kits, brakes don't last forever. I just cannot seem to locate rotors only. Any help is appreciated. Searching just brought me to a lot of kit discussion or "buy a kit" statements.

And with a search for compatible 5x5" wheel patterns I think I found an answer. B-body Impala SS seems to have rear slip on discs with 5x5" pattern. Going to go get a set Friday and see how they will work out.

Late 70's early to mid 80's Cadillacs had slip on 5x5 rotors also

Astro looks like the ticket. Impala rear is only .79" thick. Astro is the right 1.25". Also the Astro has a deeper hat it looks like. Should put the rotor in farther for the weld on mounts. Thank you very much!

I thought Astro's were 5x4.75" lug pattern.

Can anyone confirm the lug pattern of the AWD Astro's?

Thx!!

Are guys using the Astro AWD front or rear rotors? I ask because the fronts are slip on units too.

Late 70s Linclon MarkV rear disc brake rotors are 5X5
11.5" x .81

I just put in 2001 and got what I was looking for. Front rotor btw, I think the rear is drum.

Yep I ended up using like a 2000 AWD Astro Rotor. Lined up great and fit well on my aftermarket 5 lug axles. Has to be AWD since they have the newer style unit bearing construction. 2wd is a hub/rotor combination for old style bearings. Parts guy tried to give me 2WD ones at first despite my asking for AWD.

Ford Assassin · 04-21-2013, 04:40 PM

I too am running custom 5 lug axles, but for a 9.5" 14 bolt. They usually came 8 lug, some '90's had 6 lug, but the only factory 5 lug 9.5" 14 bolts were under '90-'93 SS454 Trucks.

Because of this, its been fun making a rear disc conversion, especially since mine came from a '80's 'Burb with 8 lug axles. The only think I am reusing is the housing (after being narrowed about an inch on each side to fit the axles I have.

"Tomsclassic" ebay seller who sells kits or just the mounting brackets and states he uses, 88-91 Chev K1500 rotor.

Worth buying at local autoparts store, can always take back if they don't work.
