I actually got nauseous doing my ZR1. That's a lot of 0-60-0 as fast as you can. And a cop drove by me right after I was done. I could see him looking at my glowing brakes like wtf.

if you want to steal my idea go ahead as i am sure you will have yours out on the roads again before i get a chance to with how cold of temp swings we are having. i just figured it would be cool to see how hot they get and if any glowing of the rings during the seasoning of the pads.

some people mentioned sparks etc.. during their runs to do this so i was wanting to see how extreme it really is

i believe someone on the zr1 forum said they had some bronzing of the silver rims but it went away after a bit?

I hope mine goes away, and I do agree that if it does not that it should be covered under warranty, if I knew I would have waited and done this with my track wheels. grrrrrrr

Could someone smarter than me please explain why exactly we do this? Not because the manual said so or to prevent issues down the line...but what exactly is happening during this process to make it better in the future?

Thanks!

Best,
Gene

it is to make the brake pad compound bake all the pad material compound into a better performing longer lasting material then if it is not done, also braking performance is said to be better then if not done

Gene,

JVP explains things well in his "sticky thread" that he originally referred to...

may want to bring a gas mask and some dramamine along

This is a follow-up to the article on ZR1 ceramic brakes in the November 2008 issue of TechLink.

NOTICE: These procedures are specific to the ZR1 with ceramic brake rotors.This procedure should not be run on other Corvette models as damage may result.

NOTICE: The new vehicle break-in period should be completed before performing the brake burnish procedure or damage may occur to the engine and/or powertrain.When performed as instructed, these procedures will not damage the brakes. During the burnishing procedure, the brake pads will smoke and produce an odor. The braking force and pedal travel may increase.After the procedure is complete, the brake pads may appear white at the rotor contact.

• White appearance results from light street burnishing.
• White appearance results from the heavier track burnishing.

Street High Performance Brake Burnishing Procedure

Run this procedure in a safe manner and in compliance with all traffic laws and on dry pavement only:

• From a stop, accelerate as rapidly as possible without wheel spin to a speed of 60 mph.
• Use enough pedal force to completely stop the vehicle in 4 to 5 seconds. If the ABS activates, you are braking too hard.
• Repeat steps 1 and 2, 50 times. This should take about 10 minutes.
• After completing the 50 stops, cool the brakes by driving for five miles at 60 mph.

As with all high performance brake systems, some amount of brake squeal is normal.


Racing - Track Brake Burnish Procedure

To prepare the ZR1 brake system for track events and racing, complete the Street High Performance Brake Burnish as described above. Then, complete the following additional procedure to make the ZR1 brake system ready for track events and racing.

NOTICE: 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.

This procedure should be run only on a track and only on dry pavement:

• Drive a normal, not too aggressive 1st lap.
• Laps 2 and 3 should be gradually driven faster and more aggressively, while allowing for reduced brake output and increased stopping distance due to brake fade.
• Drive Lap 4 as near to full speed as possible, while allowing for reduced brake output and increased stopping distance due to brake fade.
• Laps 5 and 6 should be cool-down laps.
• Lap 7 should be normal driving or an easy out lap.

Not sure why manufacturer of the pads couldn't have done this on a machine before the pads are installed on the car? It would sure save a lot of explanations to the police why you're going from 0-6-0 50 times.

jvp

It would raise the cost of the pads substantially. I'm glad they don't.

Have someone ride in your car to keep count, I had a friend ride in my car and keep count when I did it made it much easier since I lost count trying to focus on hitting the 70 then stopping to 10 (makes it much easier since you can leave it in 2nd) then looking for cops/etc. Felt sick after ~40 from the brake smell and the acceleration/braking. After ~40 my brake pedal went to the floor and completely lost my brakes for about 5+mins then slowly regained them after that from driving back home. Had my dealer bleed the brakes After since it boiled the fluid lol.

hence the mask and dramamine comment

jvp

Why? So that instead of one person throwing up in the car, you have two?

My solution is a bit more technical. I have a cup-holder iPhone stand that I pop my phone into. Since the phone is BT'd into my car, any sound it makes comes across the stereo. I found a counter app called "Tally Counter". It has a big button that increments a counter; it'll also announce the new number every time I press the button.

That way no one needs to keep count.

The manual for my 2015 Z06 Z07 has the procedure on page 9-9.
It say 50 stops.

I mention this because some have said there is a mistake in their manual with it saying 5 times not 50.

Has anyone just done the track burnish and not the street? Think just the track one will be ok? Thanks

jvp

It won't, no. The track burnishing will only work after the street burnishing is done. They're doing two different things to the pad material, and the street needs to be done first.
