After a few more rounds at the racetrack (Gingerman Raceway in South Haven, MI), I'm looking to replace my brake pads - again .

I can find the rear pads without issue - GM Part #22847818 / ACDelco 171-1127. They have 'em on Amazon for <$100 (and Prime eligible!).

It appears that the front pads may have changed part #s from 22976409 to 23441307 (171-1133 to 171-1141 in ACDelco speak). Most online parts "selectors" associate the 23441307 part to 2015 and 2016 models only. Is there any reason to believe they won't work on my 2014? Was there actually a change?

Thanks,
CJ

I did my own digging and figured I'd post a reply, so other folks don't need to do the same. If your C7 Z51 was built on or after March 2014, your new front pads are 23441307 (171-1141). If it was built before March 2014, you're still 22976409 (171-1133). If you're not sure when your car was built, use a VIN decoder or give your dealer a ring.

CJ, take a look at a quality aftermarket brake pad such as Carbotech.

Carbotech brakes give you:

•Assured stopping power
•Increased overall performance and handling
•Excellent modulation and release characteristics
•Better control entering the corners
•Longer brake pad and rotor life—up to three times longer than the competition!
•Non-corrosive dust

Carbotech Performance Brakes™, the world leader in Ceramic friction materials™. It was over eight years ago that Carbotech started building brake pads out of Ceramic, Kevlar, and Carbon for street, autocross and racing applications. Carbotech is the only brake pad manufacturer in the world with a complete line of Ceramic compounds for street, autocross, and track use. Carbotech-Ceramic™ compounds are known for their unsurpassed release & modulation, while maintaining very consistent torque control characteristics. Carbotech brake pads are extremely rotor friendly and contain contain non-corrosive brake dust, that’s something that has been unmatched by any other brake pad in the industry.

Our competitor’s brake pads perform like an “on/off” switch. Brake pads that perform like an "on/off" switch are upsetting the balance of the car by violently throwing all that weight forward (not to mention that you don't get any modulation with an "on/off" type of brake pad). You don't realize how much it upsets your car until you have tried Carbotech Performance Brake pads. Carbotech has almost a seven year head start on the competition when it comes to our great philosophy on release & modulation, rotor friendliness, non-corrosive dust, and an unmatched consistent bite.

Brake Compounds


Carbotech™ 1521™

The Carbotech™ 1521™ is our high performance street compound. The 1521™ compound is known for its release and modulation, along with unmatched rotor friendliness. 1521™ is also a very low dusting and low noise compound with an excellent initial bite. This compound's excellent linear torque production provides incredible braking force without ABS intervention. Carbotech™ 1521™ operating range starts out at ambient and goes up to 800°F (426°C+). 1521™ is suitable for ALL street cars, perfect for your tow vehicle or fleet vehicle.

The AX6™ is specifically engineered for Autocross applications. A high torque brake compound delivering reliable and consistent performance over a very wide operating temperature range of 50°F to 1000°F + (10°C to 537°C+). The advanced compound matrix provides an excellent initial bite, high coefficient of friction at lower temperatures along with very progressive brake modulation and release characteristics. Many drivers use the AX6™ for street driving as well, even though Carbotech™ doesn't recommend street driving with AX6™ due to possible elevated levels of dust and noise. AX6™ is NOT recommended as a race compound in most applications.


Carbotech™ XP8™

A high torque brake compound with a wide operating temperature range of 200°F-1250°F+ (93°C to 676°C+). Carbotech™ XP8™ is the first of our racing compounds. Good initial bite at race temperatures, high coefficient of friction, excellent modulation and release characteristics. Extremely high fade resistance and very rotor friendly. Perfect for track day use with any tire and can still be driven safely to and from the track. Carbotech™ does NOT recommended XP8™ as a daily driven street pad due to elevated levels of dust and noise. Carbotech™ XP8™ is a great compound on the front & rear of most open wheel and sports racers.


Carbotech™ XP10™

When Carbotech™ unleashed the XP10™ to the general public it immediately gathered multiple regional, divisional, and national championships. The XP10™ has a very strong initial bite with a coefficient of friction and rotor friendliness unmatched in the industry. Fade resistance is in excess of 1475°F (801°C). XP10™ still maintains the highly praised release, excellent modulation and rotor friendliness that have made all Carbotech™ compounds so successful. Carbotech™ XP10™ is not recommended as a daily-driven street pad due to possible elevated levels of dust and noise.


Carbotech™ XP12™

Another highly successful XP™ series compound with an excellent initial bite, torque and fade resistance over and above the XP10™ compound. XP12™ has temperature range of 250°F to 1850°F+ (121°C to 1010°C+). The XP12™ has that excellent Carbotech™ release and modulation that has made all other Carbotech™ compounds so successful. The XP12™ is more rotor aggressive than XP10™, but compared to the competition the XP12™ is still very rotor friendly. XP12™ is NOT recommended for use as a daily driven street pad due to possible elevated levels of dust and noise.


Carbotech™ XP20™

The latest iteration of the highly successful XP™ series of compounds. XP20™ is a step up from the highly successful XP16™ compound. With an extremely aggressive initial bite, linear torque curve and excellent fade resistance the XP20™ is another major step in progression of the highly successful XP™ series line of compounds from Carbotech™. XP20™ has a temperature range of 275°F to 2000°F+ (135°C to 1093°C+). Carbotech™ XP20™ maintains our tradition of having the outstanding release and modulation that has made all other Carbotech™ compounds so successful. Carbotech™ XP20™ is NOT recommended for use as a daily driven street pad due to possible elevated levels of dust and noise.


Carbotech™ XP24™

XP24™ is the pinnacle compound of the extremely successful XP™ Series of compounds engineered by Carbotech™. This compound is based on the same fundamentals that exist in all other Carbotech™ formulations. XP24™ has even more initial bite, more overall bite, and more torque along with the most linear torque curve we have ever offered. The thermal characteristics are of the highest Carbotech™ offers along with one of the highest coefficient of friction ratings offered by anyone in the braking industry. This compound is the longest wearing compound Carbotech™ offers as it was originally engineered for endurance applications at the highest pro racing levels. This revolutionary new compound has been extremely successful with open wheel, closed wheel, sprint and endurance applications. XP24™ has a temperature range of 400°F to 2000°F+ (204°C to 1093°C+). Carbotech™ XP24™ is NOT recommended for use as a daily driven street pad due to possible elevated levels of dust and noise along with the necessary heat required to work properly.


Carbotech™ RP2™

The RP2™ compound was engineered for endurance racing based on our highly successful XP™ Series formulations. RP2™ has strong initial bite, a little less modulation than our XP12™, but still maintains the rotor friendliness of our XP™ series compounds. RP2™ has great fade resistance with a temperature range of 250°F to 1450°F+ (121°C to 787°C). RP2™ is as rotor friendly as our XP™ series compounds. Carbotech™ RP2™ is NOT recommended for use as a daily driven street pad due to possible elevated levels of dust and noise.

I ordered front and rears just a few hours ago from Trunkmonkey, before I read your post. I was a bit confused as well with the different part #'s but looks like I ordered the right ones

and they cost almost half as much as what my dealer charged me the first time I had them replaced

CDH76

Is the price listed for one set or both pads for the front driver and passenger?

Achmed

I think each price is per axle, ie you buy one front and one rear.

GM stopped making the front brake pad for Corvette Stingray Z51 manufactured before March 14. Part number: 22976409 I don't know which is the replacement part for this part since I'm looking for stock replacement Z51 brake pad. Please advise.

PHILLY JOE

Have a early stingray conv.t z51 . Had to take it back to dealer early . Pulsating brakes. They gm had a up grade on pads and rotors. All changed and fixed the problem. Do not know the p/ns.

BrunoTheMellow

If you're going to keep tracking, id get a track pad set. I do carbotechs xp10/xp8 which are fairly easy on the rotors. I'm on my 3rd set of pads overall and my rotors have barely decreased in thickness. I bought 1521s for the street to match. The difference in performance is insane even with a mild track set and it is definitely a safety requirement if you start really going fast.

911Hunter

Bump. To see if someone knows the number for stock Z51 brake pads for early prodction ‘14 Z51

Foosh

See answer to your question in the parts for sale section. There is no different stock number for early production 14 Z51s. GM just changed the part number. All Z51 pads will fit all 14-19 Z51 calipers.
