Upgrade your HHR with Cobalt SS brakes

[@regt7748]

Yes!! I have a 2007 LT PANEL i want to do this swap on. I never feel like having to rebuild drum brakes. Cool!

[@stevedeleon8775]

We were very fortunate that the dealership equipped our 2011 HHR with the Cobalt Z24 option when it was brand new..we bought our HHR in 2013 from a one owner who drove it lightly only with 24,000 original miles..it now has 110,000 miles👍

I’ve been totally down with this swap I just couldn’t figure out the emergency brake issue but you have solved it for me thanks a million now I’m more excited to do this swap

[@BigNateSilva1984]

Houston is hard as hell to find this rear assembly ...hope to do this cause im sick of the drum adjuster bolt

[@TheChozen317]

Thanks for this excellent walk through. I am now trying to find my donor cobalt to do the same rear end swap.

You just saved me so much money today jack ❤️‼️

Hi there, I watched your video a few times and I am impressed with how well your conversion came out. You seem pretty mechanically inclined so I thought I would take a shot to see if you could help me out with a question I have. This is about my 09 HHR SS. Can you tell me how to adjust the parking brake? I am about to put new rotors and pads on my car and am pretty sure the parking brake will need adjustment after the installation. My car already has rear disc brakes. I can picture the pb lever will go all the way up with all that new slack on the cable. Any help will be greatly appreciated. Thank you so much.

Supercharged and bigger brakes, why no coil overs for suspension or is that next

[@frankschultz2382]

Will this work for all year HHR? I have a 2011 and I can get the rear axle from a 2006 Cobalt SS do you think this will work? I know the supercharger worked off this car on my HHR with some modifications so wondering it this would work also. It would be nice to have disk rears

[@josephcarlson1774]

Yes. It work on a 2011, and I also supercharged mine with all of the Cobalt SS and ZZP stuff.

[@magma_plays8269]

Anyone know why the abs comes up and the ebrakes ?

[@briandelong6056]

Thanks for the video. Will this conversion require 16” wheels?

[@honeybee1420]

Thank you so much for all of your information, did you have to swap out any kind of computers or anything to get correct brake pressure at the rear?

[@josephcarlson1774]

I didn't have to change anything. They use the same master cylinder without a proportioning valve.

[@user-lw8jk6nv7l]

I just made a plate template so people don't have to do the whole rear end conversion. But I still did it on mine for authenticity :P

[@LuisTorres-ot2ib]

This can be installed on Malibu 08-12??

[@josephcarlson1774]

I don't think so because they're different platforms, but I haven't looked into it.

[@roadrunner1391]

what did you do about the abs lite my stay on after i did the same thing

[@josephcarlson1774]

My donor axle had a bad sensor in the LR wheel bearing. Changed it and I was good to go.

[@robertpeake6762]

Did you have to change master cylinder and proportion valve?

[@josephcarlson1774]

No, the part number is the same on the SS master cylinder and the HHR

[@robertpeake6762]

Cool thanks. Probably going to pull a part they have a g5 with rear disc brakes looks all the same as colbolt and hhr!

[@NotMyNameEither]

Nice video. Thanks!

[@luckylynch6104]

Is there any other cobalts that came with rear disc brakes besides the SS? If so can you use rear disc off of a 4dr? Great video btw, great information.

[@josephcarlson1774]

Yes, any disc break rear axle from the cobalt or G5 will work. After '07 the naturally aspirated SS was rebadged as just the "sport" model.

[@luckylynch6104]

Joseph Carlson thanks for the info.

[@allanenders5525]

Did you find that you had to swap out the master cylinder/ proportioning valve, to get the brakes to function correctly, also I didn’t notice in the video, did you install the HD sway bar on the rear?

[@josephcarlson1774]

I looked up the SS master cylinder and proportioning valve and they are the same part number as the HHR, so I just left my stock ones in place. The 07 SS I parted out didn't have any extra sway bar in the rear.

[@allanenders5525]

@@josephcarlson1774 thanks for the information

[@cliffweatherbee6914]

Does the SS have a different valving in the shocks/struts? Or are your KYBs better? Does the Master Cylinder operate the rear discs the same as the drums??

[@josephcarlson1774]

This HHR was optioned with the same FE3 "sport ride" suspension that is on the SS. I think the KYB's are better than the factory ones as well.

[@josephcarlson1774]

And its the same Delco part number between the master cylinders and there isn't a proportioning valve. Everyone I've seen do the swap doesn't have an issue using the factory master cylinder.

[@cliffweatherbee6914]

Awesome! Great information! Don't forget to do an update in a few months. I'm going to try and make a few videos on my Jimmy in the next few weeks.

[@msdos730]

@@cliffweatherbee6914 So im doing the same swap on my 2007 ion. I think if your car comes with abs your good but i think my ion 2.2 has a valve instead of abs because my rear brakes drag after the swap.

[@Thermos017]

Is the rear caliper small enough to still get the spare on? I know the factory spare in my 06 HHR won't fit over the front calipers, it has to be placed on the rear drums. Also, are you running stock size wheels on that with the larger caliper bracket? There's not a lot of clearance between my factory wheels and the caliper in the front so i'm not sure I can do this mod with my current wheels.

[@josephcarlson1774]

I actually haven't tried the spare although the spare from the SS cobalt looks to be identical. I have test fitted factory 16" steel wheels and they clear without an issue.

[@hlmmoore]

Anybody else notice that the springs just removed their self. I was afraid it would jump out and hit you in the head.

[@josephcarlson1774]

Factory springs would of had a little tension on them, but these cobalt lowering springs just fall out.
