For the sake of comedic timing, never use the drum set again. But make sure it's in the background of any joke shot.

[@TheFarCobra]

I believe that the new Vette has brake by wire.

[@igorp]

So will this only work with DRUM brakes? Budum-Tsss

[@PedalBox]

I going to buy merch in trade with Lucas beer.

[@michaelaguilar9751]

The whole bit about going and getting a drumset is exactly the kind of unnecessary and hilarious over-engineering I have come to expect and enjoy from this channel.

[@spavliskojr]

its very much like a family guy cut scene gag!

[@Smidge204]

Now he needs to build a robot to play rimshots for him, for maximum efficiency. Since detecting when a joke is uttered might be hard, it should probably just activate whenever it detects a sound level drop and more than ~1/2 a second of silence.

[@ArranShort]

I'm new to the channel and I've literally just subbed because of this! 🤣

[@patrickodonnell9891]

I thought he was going to get some beer!

[@station240]

I suspect it's was his drum kit all along, and he just drove around to block twice.

[@HomeBuiltByJeff]

Nothing better than a video that gets straight to the point... ...of course there is always time for a couple of Dads jokes along the way ;)

[@kevinburke6743]

Dad to Mom, did you know that the red stripe butterfly 🦋 hatches on 1st of May & only lives for 2 days? Mom, that's just a myth! Dad, no it's a butterfly!

[@resistanceisfutile]

As a dad, I wholeheartedly approve of the dad jokes.

[@ItsaDigitalHamster]

Watching this channel never fails to make me laugh :)))

[@maxcactus7]

Oh GOSH, the slow drag of the drum set back into frame for the final joke just put me in TEARS!! 😂 I salute your dedication to comedic ambush-ery, sir!!

[@guidoheeling1179]

Saw it coming for about a minute but it was still awsome

Yep. There's a reason we get two eyes instead of just one.

[@tinman7551]

Reached a level where you’re just playing with the video audience it’s really really awesome 🥰❤️

[@GrubbyPaddler]

2strokestuffing has gone down a similar path and it's fantastic...

[@uliwehner]

video audience is a bit of a contradiction in terms.... at least for us old latin students

[@krazed0451]

@@GrubbyPaddler Not really, he's doing this shit full time now and seems to be going backwards most the time and avoiding doing what he's been promising. I love 2t Stuffing, but he's been frustrating me for the last few months. At least Matt hasn't made promises he doesn't keep.

[@tinman7551]

I Englished like a freaking champ there didn’t I. Must have been using the keyboard with my nose. “You’ve reached a level”. Jesus Christ, I’ve made a mental note cut back on the cough syrup.

[@GrubbyPaddler]

krazed0451 more of a reference to the humorous cuts in the videos... I for one don’t care about the projects as much as enjoying their video style and entertaining personalities, with an engineering backdrop.

[@traingeek2000]

If you have a CR-V gen1 iBooster and don't want to use the remote reservoir, the direct mount reservoir from a 2014-2020 Mini Cooper fits with minor plastic trimming near the front inlet port. I found it was less expensive to buy a complete used master cylinder than to buy the tank alone new from the dealer.

[@lougubrious9624]

The drum kit gag was so next level. You are the best, Matt.

[@gsmdo8836]

Best episode yet Matt - as soon as I saw you loading the drums into the car, I thought “No - he’s not going to…” Dragging the kit into shot later made me laugh out loud 😂🤣😂 Keep at it - once again, I was vaguely aware of how a vacuum servo worked, but your short explanation (with excellent VAs I might add) made everything clear. Merch ordered 👍😃

[@mr_voron]

The level of trolling your commenters in this video is unmeasurable with normal instruments. I’ve spit my coffee laughing at least twice. Bravo.

[@bend1483]

It’s the absolute deadpan delivery that is…

[@Hawk7886]

Pretty gross spitting all over the place. You'd think you would learn after the first incident.

[@mr_voron]

@@Hawk7886 you’d think, but no…

[@ШамильВалиуллин]

Yeah, me too. Hehe ;)

Immeasurable with normal instruments, but it CAN be measured with drums. …I’ll see myself out.

[@irontrev1640]

Listening to his reasoning is like reading a McMaster Carr catalog that explains on the header of each section how the parts work !! Now when I read a service manual my mind’s voice converts it to super fast Matt voice, Love it ! Keep making videos Matt

[@PeterDenHartogEng]

Keep cramming in the info, even if it's history from the historical history times. I love the context you give around your design decisions - I've done my own engine swaps but I learn new stuff about stuff that I thought "just worked" every time I watch one of your videos.

[@jacobrzeszewski6527]

I remember my first car annihilated the catalytic converter and it got completely plugged up. So the exhaust gas with no where to go, went through the EGR and created positive pressure in the intake. I’m not sure which was more terrifying, my brakes going stiff, or the pedal going to the floor. Because Ford gave me both of those experiences.

[@EllipsisAircraft]

They also pipe engine sounds thru a plastic tube into the cabin. So you can hear Fords mechanical failures more clearly.

[@gregorymalchuk272]

What model and year of Ford was that?

[@davesmith9325]

Totally cracks me up, this is the funniest yet. Being serious, go off topic as far and as often as you like, it's all great : the all important difference between Matt and the time wasting padding channels is your relentless PACE, we are never waiting for you to get to it, we are breathless trying to keep up ... Best channel on KZbin : Yay!

[@lost4468yt]

I love the longer in depth videos. Much better than a 2 minute video where you just explain it without actually taking one apart etc. And the algorithm prefers longer videos as well. So it's a win win. All hail the algorithm!

[@ChrisZBr0wn]

literally the best channel on youtube. The dragging out of the Lucas joke was %1,000 worth the wait.

[@PaulLeavitt]

This is the best 15 minutes of info/trolling I've ever spent. 😂

[@therealgaragegirls]

Thank you for the tip on the 2018+ Honda Accord brake booster. I got a Gen 2 Bosch iBooster complete off ebay for $157 shipped. This will make my 1955 GMC pickup MUCH safer! So thank you! ❤️

[@lighswarm175]

The smirk at 14:15 had me rolling, another excellent video as always.

[@anisankaran2365]

"I really should've taken a break, before I broke into my brake booster; now I have a booster that's broken and it won't boost the brakes." absolute tongue twister

[@Ebbyman413]

"I don't even know why you're still watching!" - Because if I don't, I miss the overly-elaborate rim-shots that take these videos to the next level. All Hail the Algorithm!!

[@troo_story]

Why thank you.

[@DirtSweatGears]

I just realized, a 2018+ Accord brake booster WITH master cylinder and reservoir is less than half the cost of just a master cylinder for a 76 Triumph tr7. And as an added bonus, I'll have an opportunity to add a completely needless switch to my stupid cyberpunk car.

[@CowfordGarage]

I lol’d when the brief history on springs started. 😂👌🏼

[@CowfordGarage]

Also lol’d when I saw the drum set being picked up and realized where he was going with it. 😂

[@bobbysenterprises3220]

The tech was there. My 1992 caddy has a totally electric brake booster. 4wheel abs. Hydraulic brakes with electric assist. And yes it is a Bosch system. Thanks for video. Good work

[@Matt0x00]

Such a great mix of comedy and information. No matter how big your channel gets it I will still consider it underrated.

[@jamescolgrove9411]

The sliding of the drum set in slowly at the end is the best. Great info and entertaining.

[@gannas42]

You had me at that pause and the intro to history of brakes. :D

[@videogalore]

Hear me out, but you genuinely make the world feel like a better place, knowing that there are awesome people like you out there. Takes away some of the doom and gloom that seems to be prolific at the moment!

[@Equine_moon]

Or as we call him: Lucas, Lord of Darkness! And my own: the Harnesser of Smoke (‘cause if the smoke runs out it’s impossible to put in again🥁) Best one yet Matt!

[@RustOnWheels]

I know someone with an Aston Martin V8 Vantage from the eighties and I always thought the Lucas jokes were just being funny, but when I saw her car for the first time and it would just randomly sound the alarm, sparks would come from under the dash when pressing the brakes and sparks and smoke came flying out of a corner in the trunk when that opened, I finally understood all the jokes. Beautiful car and engine though.

[@hkad6252]

Check out the braking System on the Audi eTron. No contact between brake pedal and brakes, only in emergency fallback mode you get a physical connection. All that in one box. The result is perfect, seemless blending of regen to friction brakes.

[@CAHelmer]

Trolling of the highest order. Love the car build, stay for the comedy.

[@BruceEEvans1]

I am not a car guy, but I am an engineer. I appreciated your explanation of brake boosters. I like your video.

[@TheMrtMts]

For the algorithm gods - Matt taking ibooster apart is just like watching a kid take apart his first derelict appliance found in the attic. Stuff flying, bloody knuckles 😆

Man I love your video's. Please never change the format they are absolutely hilarious and very informative. Keep up the good work.

[@ESPLRG]

This was bloody hilarious and of course informative as always. I watch these purely out of interest and I can’t get enough. Keep doing what you’re doing, loving the content.

[@vandyFixer]

The motor sub assembly is where all the magic smoke is kept. You'll know iits true if you've ever managed to let the smoke out, it rarely runs again

[@joshgreen2164]

The slow burn with the the drum kit. Was hilarious both times!😂😂😂😂

[@Martin42944]

I appreciate the extents you'll go to for a joke... and making a 5 minute video last 15 mins. ...I'm actually serious. For your next video, please make a 5 minute video last 30 minutes.

[@Goodgu3963]

For get that lol. Start out with a 0 minute video and make it 30 minutes. I would pay money to watch Mitt just get distracted and pretend to do car related shit for half an hour XD

[@Twisted_T_Racing]

I work in a automotive reseatch facility and we have found that the Prius Prime and the 2019 and newer Chevy bolts use brake by wire. The boosters are set up pretty much the same. The cool thing is when the car is going to auto brake mode and you don't press the pedal the electric motor still pushes forward on the real master cylinder slow the car down. The same is also true for one pedal driving mode. As you let off the accelerator and it starts to come to the point regenerative braking is not strong enough to slow the car it will use the motor in the booster to applied mechanical brakes to bring the car to a complete stop. In the event the braking system failed they have a mechanical backup that you show in the video during tear down to still stop the car. For the company I work for we do Dyno testing and is completely automated using electrical input to the throttle pedal and now the brake pedal so we can effectively stopped the car and speed up the car from a computer by tapping into the brake by wire and drive-by-wire systems.

[@12x2richter]

It'd be super trick if there was a way to harness that with a front camera so you could do basic collision avoidance as an extra safety feature.

[@AtomicGarage]

I love all your videos but this one takes the cake!!!!!!!! That’s a great video right there. And the drum slide at the very end was GOLD. Also very informative even tho I am doing no ev build. I learned A lot

[@danebarrett677]

I'd say in the last decade of watching KZbin to learn things, and I've learned a lot of things, I havent really given many subs and ice maybe commented a few times. I know it's kind of shitty, but it is what it is lol but I'm liking, saving, commenting and sharing because this video just saved me about $2k on my project car and I'm over the moon right now. Thank you so much!

[@ElSelcho77]

Dude, everytime I see an new upload (you're on FIRE btw) I get a huge smile, because I know I'm in for another treat. Thanks :)

[@ehochmuephi8219]

As Bosch Engineer working on iBoosters everyday I approve this message and everything stated in this video. Especially the "don't take the sonsor out of the booster part". And I really flinched when you opened up the boosters ... are you also not reading my TCD and all the guidelines ... come on man. :) Brilliant video as always.

[@gregkelley7182]

Sorry Matt, took a while to compose my self. This has been your greatest troll trashing sarcasm example. the fish story knocked me off the chair laughing, I really loved it. Don't ever get serious and lose this ability. Thanks for sharing. Oh yeah, the brake series was good too. lol

[@trevorreece6999]

You know, I watched this video before I don't know why YT recommended it to me. But I did watch it again, because as entertaining as you normally are. The whole bit with the drum set is so far over the top.

The fish in sea of this channel is certainly one of the best things about it, as are all the "money saving tips" for all the DIY parts. Keep up the good work--the projects are awesome, and the humor is priceless!

[@valadezjose47]

So glad I found this channel. Best of all no sponsors and secondly this guy is funny as hell. Please never ever get sponsors

[@CommanderPiglet]

hey matt! I would really reccomend you look up a guide on setting up a drumset. You managed to set it up in a leftie configuration while still having the hi-hat on the right side. I don't know how you did that but it is deeply disturbing.

[@mrbraxton]

Thanks SFM. A month or so ago I watched all your Jag vids looking for more details on how you did your brake booster conversion. I thought, maybe I somehow missed the brake booster vid,.. so I watched them again. I obviously never found what I was looking for but I learned a bunch! thanks for posting this vid.. ...also, thanks for mentioning the accord booster. ...this is one of the BEST videos I’ve seen of yours, love the trollin’ and drum rollin’. Seriously,.. big thanks.

[@petehalasz7547]

You are hilarious and a bloody genius.. I've been a licensed technician for over 47 year's and worked on literally all vehicles , motorcycles, boat's and air crafts and I am thoroughly impressed by your research and ingenuity.. you look at a situation, dissect it, research it and Bada Bing,, Bada boom.. those who complain are obviously no nothing and waiting for your results, but can't be bothered to understand it first. Keep up the great work.. love you went back to the beginning..😅😂

[@JustInTime0525]

God damn I love your videos. It's like TOT but with automotive work, where you show your face but don't do timetravel! (yet?)

[@Keksfox]

I worked on the pre-assembly line of the motor unit during an internship a few years ago. Managed a project to drive the cycle time form 15s to 13s Also did some supporting research for a "fast cure" process, you can see a little drop of glue between the motor and its ECU. Thats a UV activated glue, curing very fast but noch strong enough for the automotive environment. The "main" glue is actually deeper in the groove and all the way around, attaching the motor to the ECU and sealing the connection from the elements. The main glue needed this giant oven to cure in a reasonable time, but couldnt speed up anymore. So there was this idea to use the UV glue to fix it in place, withstand the forces of the production line and allow the main glue to cure over time. Never knew if they completed that project so super cool to see :)

[@julias-shed]

Massively long setup. Lol. Mighty fine algorithm 😀

[@schoolForAnts]

[@mrblond750]

I love technology. It’s so awesome what can be done. What I love more is simplicity. My 3/4 ton’s brake booster started leaking causing the engine to run lean. Disconnect the vacuum line, cap it at the intake. The truck still stops when you press the pedal. Magic.

[@randycarter2001]

ABS Power Brake Inc. sells an electric boosted brake master cylinder. It has a small pump you put low in the car. Ordinary brake lines are run between the two. It uses the brake fluid as a transmission medium. It's for retrofitting classic cars that never had power brakes. Doesn't stick out like a vacuum booster.

[@fredflintstone8048]

I am a firm believer in trying to maintain an attitude of gratitude and more specifically to have some appreciation for youtube content creators that are teaching me something which quite often means putting up with people who think they are funny, or try to be funny when there's nothing funny at all about them. However short they keep that behavior, it does add no value to the video, only time. Valuable time. Most often they're amusing themselves and maybe even giving themselves a chuckle. Perhaps a small worthwhile price to pay given the effort it requires to produce videos.

[@ahmethussein1125]

hi Matt, I've obtained a brake booster from a honda jazz 2021. this unit is in 2 parts, the motor/master cylinder and an abs/control unit. I was wondering your thoughts on using this setup, fitting the motor in the boot, then using the honda jazz brake pedal possibly coupled to some parts of the controller unit.

[@bah5310]

My RV project (that wasn't supposed to be a project) kicked my ass this past weekend. Thanks for the great video. I need a trap set now.

[@GilliamVespa]

13:35 - scrolling through ebay... i see the ford focus brake reservoirs in that list. the ford focus has a 2 part res, which the pics show the upper part only, but that attaches to the lower part via hose. in your application the lower res could sit at any angle.

[@EV-olution]

This has to be one of your best videos. The time you spent on the extra content, which is absolutely brilliant by the way, is, in my opinion, very well spent and hopefully sends a tidy little message to the goldfish out there.... oh wait, this sentence is longer than 8 seconds 😉. Excellent video, thanks for taking the time to explain everything. I am a details kind of guy and appreciate the extra info. That's how I make my videos 😎.

Oh sheeeeeeeet, the filler with the drum set after explaining how people use useless fillers is awesome! All hail the algorithm!

[@xzp]

im not done watching the video but i work in the autoparts industry and i sell brake boosters all the time but never really understood how that worked. ive never had one fail on me so ive never needed to replace it. immediately after the "inside the brake booster" segment i thought about what would happen when they failed. now understanding how the vacuum increases the braking pressure, it stands to reason that a symptom of a failed brake booster would be an extremely stiff pedal, which i've experienced while pressing the brake with the engine off. now that i actually understand how they work, i'll both be able to assist customers who experience this symptom, as well as diagnose the issue myself if and when a brake booster goes bad on me. no, i don't think i mind these extra talking segments one bit :)

[@okjd159]

The reason for that the Lucas joke was that when they flew WWII planes from England to France the planes had a tendency to crash in the chancel before the made it, because of the electronics which was made by Lucas. As compared to the US Planes.
