Hey im am starting to design a conversion kit so you can take your drums of and replace them with disc i just need a little insight on what i will need i work at a front end shop so i have all the tools and i have knowledgeable people that can help me build it comment on this thread with any info i am rolling in a 2012 eco 6 speed mt

Best bet is to find out part #s for an LTZ as they come with discs from the factory. If they are like most car makers you should be able to order the parts and swap them over.

Im not stating that is all you have to do only thats where I would start if attempting the same. I've done rear disc conversions on Hondas and it wasn't all that hard. The hardest part was routing the ebrake cables. Oh and you'll also want to use an LTZ Proportioning valve to get the proper power distribution.

Neat! Let us know how it turns out, and what hurdles to watch out for!

The only snag might be the slightly different rear suspension setups the Eco has over the LTZ. The Eco has a regular twist-beam, while the LTZ has the Watts-link twist-beam.

 

[FatKidsCruze]

That was my thought as well different suspension setups may be a pretty big hurdle. But then again maybe not research will tell though!

Hmm better yet just find a wrecked LTZ In the salvage yard pull the whole rear suspension including rear hubs and swap it out on your Eco.

I wish I could "like" this, hahaha

Thanks for the advice i know i will have to put the master cylinder off the ltz to for the reason that the two sectioned brake fluid resivors are for front and rear brakes.

You dont need to "make" anything, its a bolt on affair with all GM parts.

That's exactly what I was going to say.

How do you know the mastercylinder needs to be changed? Generally, GM front drivers are a "x" split, not front/rear. There are no proportioning valves anymore. Just curious. I would check to see if the m/cyl p/n is different. If so, it could have a different fluid reservoir size to compensate for different fluid volume needs for the calipers vs. drums.

Oh wait I can!

The Eco has the same suspension minus the watts link, it shouldn't have anything at all to do with the brake system.

Well there ya go! Now just go get ur parts Op and enjoy your new rear discs.

They did it - SEMA 2011 - R Miller Chevy Cruze

You could look into the Wilwoods.They are a USA company and have a huge inventory. You can pretty much pick and choose what parts you want and put everything together if they do not have a kit. May need to make some custom hats for the rotors and mounting brackets for the calipers, but any machine shop could do that.

Or you could go with GM parts which have properly sealed calipers and are designed to work with the car from the get go, disc brakes on the Cruze just bolt on, its not like a Cobalt with a different rear axle between drum and disc cars

This is making me want to swap mine out...

I already have it planned for when I get mine.....that is if they dont come out with a "big block" version before I buy one. If they dont verify at least 200hp or more version for 2013, Ill probably just buy a 1LT late in 2012.

 

[H3LLON3ARTH]

well because the master cylinder and the resivour on top are different its like that on every car that has rear disc brakes how do you think the fluid get to the back brakes.

Are you serious? these arent the days of full drum brake cars where we have single outlet master cylinders. Cobalts all use the same master cylinder regardless of brake system(10.2" disc w/drum, 11" disc w/drum, 11" frt/rr disc, 11.6" frt/rr disc, and Bremob frt/rr disc), and Im almost positive though I have checked part numbers, that Cruzes do as well.

i looked at this briefly and decided ti wasn't worth the money unless you found a wrecked Cruze, But from what I ventured you need
calipers
Rotors
Pads
Backing plates
wheel hubs
rear brake lines

Think that is all it really takes, the master cylinder is the same, as is the ABS block. There is no proportioning valve to worry about

That sounds right except for the hubs. Could you explain why you believe you need hubs? I have zero reason to believe that to be true.
