Im 10 months late. But im an a.s.e tech for subaru and honda. I can garuntee you it takes your chevy dealer less than 1.5 hours *tech pay rate* to do a brake job, your car sits there because the line of cars we have to get thru before we get to yours is 3 days long. Anybody reading this. Yes. Your car sits at the dealership for days untouched, 150 customers a day. 6 mechanics. They could explain that to customers but they are convinced nobody would understand. So they just let ppl pile in and get mad at the mechanic. When really the dealership itself is full of shit. And shit rolls downhill. Mechanics are at the bottom of that hill. Rant over.
You have to remember that these brake changes are transferring in full kits, what I assume to be pre-bled assemblies onto a car that was designed with quick brake changes in mind. Both sides in 15 minutes solo without fully assembled kits and a car to take it is impressive in itself. It takes me 30 minutes or so to change both sides with confidence that I didn’t fuck up.
Bruno Pinheiro oh yeah I didn't see that they put the same front tires on. Interesting, why wouldn't you put on an entire fresh set of tires if your spending time pitting?
@@NatedoGP They can't fuel, change tyres and the brakes at the same time, due to the limited number of crew members. So, a tyre change would happen *after* the brake change, and add about 6-8 seconds or so. Notice that they change the brakes right under the fueling time. It's better to stagger your tyre changes as to always have your pitstop be just as long as the fuel time (which you always have to do anyway, and can't be any faster due to regulation in the refueling fuel flow).
A ton of engineering when into the design of the quick release brake assembly. Even though the drivers get all the glory, let's not forget the brain power it takes to design and test this stuff.
Check out a muddy motocross. Been around for years and years, just coming into the car game. In Moto b/c of all the mud they have pull away lenses on goggles. So when you see a guy hit a decent jump, sometimes he pulls off the tear aways mid jump haha.
Racecar windshields are Lexan for safety. Lexan is much softer than glass, so it pits easily causing them to haze up mid race. They added sacrificial layers so that they can tear them off as they get damaged.
Watch the second from the right guy at the start of the video. He attaches an air line to the car which activates pneumatic jacks mounted under the car
Caliper is pre-filled and bled and they use quick disconnect couplings on the brake lines like these: www.jegs.com/i/Allstar-Performance/049/ALL50209/10002/-1 Note the hose sticking out the new caliper around 0:24
Bro this is a factory built race car its not like your typical car nor mine ...mostly everything on that car is quick release even the entire brake assembly
Pre-bleed on the swapped in calipers/line and no-spill quick connectors. There might be other things I'm not aware of but those are the two primary items.
yup they got $400 word pre-bleed calipers on each caliper the whole system is designed for track so like you see even the wheels just have one bolt not 5-6 all upgrades to save time each of those prebleed caliper attachments cost $400ish
@@turmat01 I don't understand what you mean. If you've ever done PC watercooling, it's the same concept - no spill QD connectors. Except, of course, that all these lines are steel reinforced or hardline to keep the brake fluid pressurized at all times.
They bleed pre-bleed all the calipers and lines. All the brake hoses are on quick disconnects that close off when they aren’t connected. So when they change the calipers there is no bleeding necessary
You see the guy pull a line off the right side of the car towards the end? Air line that operates air jacks that are installed in the underside of the body. Super cool
@@zachlidl Only reason I can think of is the switch away from pushrod to overhead and flatplane. Personally I think the old engine sounded meaner, but the layout of the new car is probably superior.

What a nice celebration
Awesome as hell
“Yo buddy, are your brakes still alive?”
And yet my Chevy dealer takes two days to do it. 🤔
Lol
Your car doesn't have a quick release brake assembly lol
With the right tools, you can do it at home within 30min per corner
Because they have to charge you by the hour

and i was all proud about being able to do both sides in 15 min
Still impressive imo
The fact that you can do it yourself says a lot to begin with, most people can't even change their own brake pads.
I mean with just a jack and hand tools, that's not bad, they have pneumatic impact tools and a team.

You absolutely f**king should!
It'd be hilarious if they started celebrating, then when they went to bring everything inside the garage they notice they have 3 brake rotors lol
What 🤣🤣🤣
ahahahaha
This is so badass man 🙌 good shit fellas
I don't know what would be more cool, actually driving in Le Mans or working in the pit crew.
Brake lines to calipers on quick connects. 👍
Wow thats pretty dang cool.
Any reason why they didn't change the rear tires during the stop?
New rears and older front tyres would be understeery as hell, probably.

deamn what a monster pitstop...

What about the plastic sheet they pulled off of the windshield? Are there multiple layers that they just pull off each time they pit?
Yeah, rather than have to clean the windshield, they use the plastic and tear it away when they pit.
I was thinking the same

Pneumatic Jacks are installed within the car. Look it up, sounds satisfying.

Good job
how do they not have to bleed the brakes
Caliper hydraulics stay sealed during the pad and rotor swap
@@cellphonelightsaber But they still swapped out calipers.

who makes the brakes and hubs for the c8r ?
wow! good speed~
The dealer is still insist it's a 15 hrs job
Excuse my ignorance but why do they not need to bleed the brakes in this instance?
Pre-bleed on the swapped in calipers/line and no-spill quick connectors. There might be other things I'm not aware of but those are the two primary items.

the whole system is designed for track so like you see even the wheels just have one bolt not 5-6 all upgrades to save time

what are the hoses they plug at the front?
Quick disconnect lines for the brakes.
@@spdcrzyThey force the calipers open so brakes are easier to change?

impressive
this use to be illegal before 1960s le mans
It technically wasn’t becase of the wording of the rule in the rule book.
Meanwhile the mechanic at jimmy lube takin a whole week
The brake oil wont get air after replacement?
The brake lines have quick disconnects that let no air in. The new set is Pre-bled too so no air is added in the system
How they bleed the brakes system?
They bleed pre-bleed all the calipers and lines. All the brake hoses are on quick disconnects that close off when they aren’t connected. So when they change the calipers there is no bleeding necessary
How do they lift the car without jacks? :-O
You see the guy pull a line off the right side of the car towards the end? Air line that operates air jacks that are installed in the underside of the body. Super cool
merica!!!
Nice
This Sound
hell yeah baby XD
Does anyone have details about the calliper assembly on the car? They don't use any tool the swap calipers and dics!
They swap the entire assembly
They redesign the brakes so they can just take out and swap the whole assembly like tires
My Chevy dealer can't do it
👍🏻👍🏻👍🏻
Pog
😱😱😱👍👍👍

Pit crew wins races!
How the heck car lifted itself?
airjacks that are built in the car
Air Jacks, if you look at the guy second from the right he puts an air line into a port that pumps up the jacks under the car
