LS-1 rear disc conversion

Hello all, and yea very familiar with EB Miller, stuff, I was just looking to do my own swap, find a set of LS-1 rears and calipers. I have a drum rear now
(91 Z-28 350 car) and want to convert. Has anyone done this, and what bracket did you get from EB, and what rotor are u running. I have 17 in wheels also. Pics would be great.

Mike

Re: LS-1 rear disc conversion

I've done it. It's actually really easy and you can retain the e-brake function of the LS1 setup. It's been done several times and is a great rear disk option. Here is a link to the article where I got my instructions from: http://www.thirdgen.org/ls1reardisc

Ed sells a thirdgen (custom) LS1 parking brake cable.

I didn't buy anything from Eb (sorry, Eb). I got my braided steel lines form Kore3 and I bent my own lines. the e-brake cable is actually quite easy to figure out. What I did was connect the LS1 e-brake cables to the stock 3rd gen brackets under the car. Then I cut the stock line long enough to reach almost to the bracket, connected the stock line to the stock lever bracket and coupled the LS1 and 3rd gen lines together using small U shaped couplers. It worked great and you get to use the stock stuff. Just a couple of cuts and two U couplers.

Yes, you have to use the stock sized rotor. i just had them turned at a local auto parts store.

Re: LS-1 rear disc conversion

Not of the e-brake cables, though I should take some anyway for reference, but it's been raining for days here in Cali. On a dry day I'll take the pics. i have to go under the car soon anyway, I'll take some then. Just couple the the stock and LS1 cables together, works like a charm.

Re: LS-1 rear disc conversion

Ed sells a complete kit for this which I am very close to buying.. I just can't get a hold of him.. Sending him emails doesn't work. I have yet to try calling though. I am sure this kit is phenomenal like the front LS1 kit I have on my car already.

Re: LS-1 rear disc conversion

Yes I did notice he sells a kit but I can do a little painting and piece one together for a little cheaper, I have several other mods going on as well just trying to be resourceful with the $$$"s. lol

Re: LS-1 rear disc conversion

I was lucky with my kit; I only spent $160 on a used setup from ebay. They pop up for a good price from time to time.

Re: LS-1 rear disc conversion

I just checked, and there is a complete LS1 rear brake set on Ebay right now for $190. Rotors need a turning and calipers a good inspection, but everything is there.

Re: LS-1 rear disc conversion

Hey guys,

If I wanted to peice together the set, I wouldn't mind using a used kit like this one:

http://cgi.ebay.com/ebaymotors/LS1-R...Q5fAccessories

Is this the same parts as Ed's kit or is there more involved than just buying these parts and slapping them on? (I have drum brakes currently). If there are extra parts which ones exactly would I need (planning on keeping parking brake functionality as well).

Thanks!

That's the route I went also, but I had a disc rear also, so pretty much bolt on the axle. I used the brke cables (including tunnel bracket and brake handle from a donor LS1 car). Changing from drums, check this link.
