who here is using the cadilac siville rear e-brake calipers? what year cady do they come off? also what e-brake cables do i need? can i use my stock cables?

cstm68 · 02-10-2009, 05:01 PM

ooops i didnt mean to post this in the projects and builds section. i ment to post it on the regular message board. could a mod please move this?

Its not seville only, its the big cars with 5x5 pattern & have rear discs

I think mine are from a 76 or something, I dont really remember

I havent gotten them on yet, but I dont think the stock E-brake cable will work, you need to adapt from the stock one on the truck to the ones on the disc calipers

Maybe someone else has more input

Here is a thread with the years & models that had 5x5

what 6 on 5.5 rotors will work with these calipers?

*Shane* · 02-12-2009, 10:30 AM

Cadillac Seville '77-'79 model years use 5 x 5" rotors ... I am using this model caliper as well. You will need to do some machine work on the axle flanges as this is not a bolt-on mod.

You will also need to make / fab brackets to mount the caliper as the caddy mounts will not work.

oops i ment what 6 lug 6on 5.5 rotors will work?

Sir Fisher · 02-13-2009, 06:44 PM

so astro vans awd are 6 lugs if so that is sweet

cstm68 · 02-19-2009, 12:24 AM

so i tried and astro rotor but it wouldnt fit over the hub,

what si the best way to convert to rear disc with and e brake?

powerbench · 02-19-2009, 12:46 AM

hey sir fisher, how do the calipers fit in a 15 inch wheel ..any clearance problems...i just bought a set of backing plates , on the off chance it will work on my 12 bolt.

**Chevy4Life** · 02-19-2009, 07:27 AM

I was going to ask if the astro rotors fit over the hubs. He probably turned them down if you tried them and they didn't fit. I used 88 4x4 front rotors and had to turn the hubs down. Most guys have them done at a machine shop. I had a bare frame, so I used a BIG drill on the yoke nut and a grinder on the hub.
I wonder if the astro and 4x4 rotors are the same. It looks like they have the bigger lug holes like the 4x4, because GM went to a bigger stud and the stud is pressed into them.

I'm on 15" rollers right now and they fit fine. They aren't stockers just cheap chrome wheels.

they should work fine... but don't quote me... i tried it with a 16" wheel and it fits fine with room to spare.

i'm so sorry guys; i gave wrong information... i double checked with my informant and for 6 lugs it's a 92 1/2 ton p/u 4X4... the astro vans are 5 lugs.

are theos off the front? and do they fit over the hub?

Sir Fisher · 02-20-2009, 12:50 AM

they are off the front of a 92 K1500. for my rear 12 bolt and yes, it fits over the hub.

powerbench · 02-20-2009, 01:10 AM

Do the Eldorado calipers have built in e-brake provisions..Do you have a pic from the top looking down at the disc and caliper...sorry to be a pain , just haven't been able to find caliper cores as of yet ,and i'm just tryin to make sure i'll have the space to fit these in my rims

Sir Fisher · 02-20-2009, 11:00 AM

hope this shows what you're looking for.

powerbench · 02-20-2009, 11:05 AM

i think it didn"t take your attachment

powerbench · 02-20-2009, 09:03 PM

oh there they are. Thanks for the pics...i just went out and measured the distance from the face of the axle to the edge of the mounting surface for the backing plate, just as i thought , it's to close to the back of the rim...then i measured the bolt holes for it to mount, they aren't even the same spacing..now i have to decide to chop up this backing plate and make it work , or keep searching.....thanks again
