I have less than 30k miles and I need new rear rotors! It's clearly evident that GM has no intention of fixing this issue for us, so I think we must turn to aftermarket support and I think ZZP has given us great products and I think this will be a great addition to the product line they have!

Please ZZP, will you R&D some new rear brakes for us LNF folk?

I am willing to bet 80% LNF owners will buy! I for one will without hesitation!

 

10/10 would buy, these brakes are getting worse and worse! At about 30k miles as well.

 

I never had a problem with my rear brakes. 38k miles

 

I've never had a problem with mine. It really comes down to what you are doing that are provoking such failures. Have you changed out rotors, pads etc?

 

Honestly, I'm not that familiar with the rear brake issue. I don't drive my car a lot so the rear brakes have been fine. I think we should look into this, though.

I like how the guy that voted "nope" doesn't own a Cobalt.

 

Yeah I changed my pads (well paid Big O Tire) and got them machined twice. They wear out faster than the fronts. I haven't machined my fronts yet at all.

I have thought about putting Hawk HPS on the backs, but someone told me Hawk pads are too soft and they wear out quicker, but spare the rotors.

You and your perfect SS/TC lol.

No evap purge problems, no rear brake issues and 38k miles to boot. I hate you!

 

If this was for the right price I'd buy a kit to get rid of the rear drums on my LS.

 

Matt, tell me the difference between Kappa Rear brakes and Cobalt SS/TC's? Also, I have plenty of friends in which I ride or drive their cars. None of them have ever complained. I've never felt an issue with my SS/TC or theirs. I also Road Race and use pads and rotors extensively(I mic them after 3 track days). What is the Bias from front to rear? I know that in the kappa's its setup with a horrid Front Bias(80% front..20% rear). This is why I use Carbotech's RP2(aggressive compound) in the rear and XP10's(Less aggressive) in the front.

 

the brake issue ive found is mainly cuased by unlubricated pins.

 

so the solution = oil squirters built into the rear calipers to apply lubricant to the pins! genious!

 

Id buy them if they came up with a solution. I had to pry my calipers off the rotors and I have 19k miles on my car owned sincs it had 8k on it and im pretty easy on brakes

 

i didnt have to change out my breaks til around 60k...and the rears were fine, i just swapped to the R1 drilled and slotted with Hawks HPS and they havent been wearing down fast at all O.o and i drive the hell out of my cobalt. i just would love a big brake kit on the back but brembo doesnt make one for us

 

Im no car guru. Nor do I really want to argue. But I really don't think the problem is the lubrication of the pins. Others have suggested this in the past as well. So I remove my calipers EVERY oil change and re-lube the sliders. With no change in how they wear or how well they hold my car with the e-brake. The issue seems to be with the calipers them self or some how in the e-brake setup. I am very easy on my car and its brakes. And I have had to replace them twice in the last year. All though I have no idea what. ZZP.... if your reading this. Figure it out please. New calipers or what ever it takes. I'm in 100 %

 

I agree, however I too am not the most savvy car guy here and not even close to it, but luring doesn't seem to be the fix.

Let's not pretend op is the first person to have this issue, and that maybe he's doing something wrong with his car.

 

i track my car regularly..... only time i had this issue was when i originally got it. pins were dry. it seems to be like a lot of other issues with this car. its hit or miss depending on the car.

theirs a solution ive been toying with but its far from cheap. running a solstice front caliper with a brembo parking brake that has a sole purpose of just being the parking brake. its big dollars for that setup though,.

 

All I want are rear brembo calipers!

 

EXACTLY!!!!!!!^^^^

 

I'm not saying I didn't know there is a problem. I just said that I'm not that familiar with it. In other words, I have not been involved in or worked on a solution to the issue.

 

It's really inconsistent. My factory rears squealed from day one and the inside pads were shot in 7k. Replaced them with factory rears. Never bothered lubing the sliders after the first oil change. Got 63k. When I took them off after 63k they were evenly worn inside and out, still had another 10 or 15k left on then easy. Got 1k on the new ones. No squealing.

 

change to something other than stock rear pads and grease the pins and problem solved, solved mine

 

Yeah sorry I worded it like I was going off on you. Was on my phone and its tough to be very eloquent lol.

Mostly just trying to say, its a real issue that a lot of people are having; a solid cheap/ upgrade/solution would be a real money maker I think.

 

I had to have my rear calipers replaced at 60000 kms. I had issues with my ebrake not holding and complained about it a couple of times. The dealership or chev paid to replace the parts and it's been good since, but I'm waiting to see if the issue happens again

 

If anything were to be done it must not change the f/r brake balance. Especially with hardcore bars being such a popular mod around here. We would have hardcore barred big rear brake cars spinning out every time it rained.

 

Hey Matt! I voted NOPE and I gotta Redline. And youy like me , have no issues. I have a Redline with LNF rear brakes. Never had a problem, 40,000 miles. I do lube the pins and the pad ends with that ceramic purple goop, and I do drive my car hard and put it away washed and dry.

Sitting kills brakes. Winter kills brakes.

Salt kills brakes. Not braking hard kills brakes. Not using the ebrake kills brakes.

You folks think you got issues, drive any half ton Ford Chevy or Dodge truck and tell me how your brakes are. lol
But I am sub'd for results if ZZP want to produce something.
