I have a Z06 on order with a TPW of 4/15. Question regarding brake burnishing for those more experienced than me. Should brake burnishing be done immediately or wait until after 500 miles? I'm confused because the break in guidelines suggests no hard braking during the first 500 miles, so my guess is that the brake burnishing should wait. I do plan on tracking the car after 1,500 miles at a few HPDE events every year at Road America. Any insight would be greatly appreciated.

What kind of brakes? CCBs?

lentscher24

Not CCBs, just the standard Z06 brakes.

Wait till after the 500 miles. In fact I thought it was longer for the brakes but I may be mistaken. Either way, don't do it immediately after getting the car. Get some miles on the odo. And if you're intending to take it to the track, just do it there.

Certainly wait 200-300 miles without harsh braking, but then go ahead and perform the recommended bedding procedure for the iron brakes. Might want to switch to a more robust DOT4 brake fluid also.

Thanks so much for the input! So it would still be recommended to switch to SRF or RBF660 brake fluid as opposed to the stock brake fluid? I did that when I tracked my C8 Stingray but wasn't sure if the Z06 came with different brake fluid. Also for context, I'm not out on track chasing record lap times. I run in intermediate group and just enjoy being able to open up the car on a great track.

Changing to a performance brake fluid in the Z06 is part of the required GM track preparation procedure. Since you shouldn't be tracking the car before 1500 miles, there is no need to rush the full burnishing process in the OM. Run the car normal for break-in for the first couple hundred miles and then you can do some "modest" brake burnishing work without doing the full OM procedure.

What is the burnishing guidance for CCB brakes on a new Z06?

You'll notice step 3 involves accelerating as quickly as possible, which means it has to be done after the 500 mile full car break in.

For CCBs from the 2023 OM Pg 176-177:
Brake Burnishing Procedure for Z06 with
Available J57 Carbon Ceramic Brakes
This brake burnish procedure should only be
run on Z06 vehicles with J57 factory
equipped brake systems.
Perform this procedure only on dry
pavement, in a safe manner, and in
compliance with all local and state
ordinances regarding motor vehicle
operation.
1. Using the friction bubble in the Cluster
Performance menu, apply the brakes 25
times starting at 100 km/h (60 mph) to
50 km/h (30 mph) while decelerating at
0.4 g. This is a medium brake
application. Drive for at least 1.6 km
(1.0 mi) between applications. This first
step may be skipped if there are more
than 320 km (200 mi) on the brake pads.
2. Apply the brakes 20 times starting at
100 km/h (60 mph) to 25 km/h (15 mph)
while decelerating at 0.8 g. This is a
hard brake application. Drive for at least
1.6 km (1.0 mi) between applications.
3. Apply the brakes 12 times starting at
100 km/h (60 mph) to 8 km/h (5 mph)
while decelerating at 0.8 g. This is a
hard brake application. Accelerate as
rapidly as possible without activating
traction control between applications.
4. Cool down: Drive at 100 km/h (60 mph)
for approximately 15 km (10 mi) without
using the brakes.
As with all high performance brake systems,
some amount of brake squeal is normal.
Alternative Closed Course Brake Burnishing
Procedure for J55 (Stingray with Z51), J56
(Z06 Standard), and J57 (Z06 Carbon Ceramic)
Brakes
This brake burnish procedure should be run
on vehicles with the Z51 with J55, Z06 with
J56, or Z06 with J57 factory equipped brake
systems.
This procedure should only be run on a
track and only on dry pavement. Brake
pedal fade will occur during this track
burnish procedure and can cause brake pedal
travel and force to increase. This could
extend stopping distance until the brakes
are fully burnished.
1. Start track lapping at lower speeds and
lower braking efforts for three minutes
of driving. Allow for increased braking
distances due to reduced brake output.
2. After Step 1, increase speed and braking
effort for the next six minutes of
lapping, gradually ending up at 90%
effort. Continue to allow for increased
braking distance due to reduced brake
output.
3. Cool the brakes by lapping with minimal
light braking for six minutes.

Do it after 500 miles. It’s essentially a non-issue for street driving. Most guys never do any of this as they don’t read the manual let alone track their cars.

Wish I knew!!! I didn’t discover until 2020 you could literally just take any decent car on the track for a few hundred bucks. Sadly I had 3 Porsche GT cars before 2020, spent more times in canyons, which is beyond stupid. Once I discovered this, I stopped any and all canyon drives and the ones I do now, I just cruise and just enjoy the drive. But ya, most guys I hung out with, also didn’t know, and like in the Porsche world, 99% of them will never see the track. Truly sad. I was luck enough to drive a 992 GT3 for 9 months, did 5 track days, and without discovering track days, I would have never got to experience the max capabilities of this beautiful GT3. Will pickup my Z06 this week and start the whole 1500 mile breakin. Can’t wait after 500 miles

this was good topic and appreciate the link above!!!!
