STOP! Car Braking System & Tech Essentials Explained 

It’s supposed to be done on every car every 2 years, it’s also good to avoid opening the brake fluid tank, it’s not just that it absorbs water easily it’s that it will remove water from the air by absorbing it.

@@MrTchou 2 years is for the common DOT3 fluid. If you're using DOT4 you should change the fluid even more often - every year is recommended.

@@trackntrail2869 i’m talking about carmaker’s recommendation for a normal everyday car, not a track car, in which it should be changed more frequently.

@@MrTchou I run DOT4 in my daily driver, which is also my Autocross and HPDE track day car.

@@MrTchou I was referring to the need to change brake fluid more regularly than every 2 yeras for track/competition use . yes of course the moisture is coming from the air , but it's getting in through all the possible routes in the system, the small period of time when the brake fluid cap is taken off to top up reservoir is not an issue.

As a British man I can confirm that we are ghostly white throughout the winter season 😂 🇬🇧

Misha had been to dominican republic this winter so yes he was in the sun somehow ;-)

It’s not really about being an excellent driver or not, ABS can regulate all wheels at the same time, you’d need 4 brake pedals and feet to be able to do the same. It doesn’t makes you stop faster but it will keep the directional control of the car (up to physics limits of course). It has been shown multiple times that ABS can significantly extend stopping distance on snow and ice for example,

I beg to differ. I've had the pleasure of driving on a skid pan before getting my licence, and experiencing the difference between ABS and no ABS (the instructor could turn the ABS in his car on and off at the flick of a switch). For someone average like me, who didn't have that excellent feel for when the wheels were about to lock up, ABS was a huge life saver and game changer. In practical, real life ABS is the best thing that happened to the average driver since four wheel brakes were introduced. A truly skilled driver will still be able to outperform the ABS system, but such drivers are few and far between.

@@hadtopicausername no driver can outbrake a properly working abs system. On a track you only use it in predictable ways (no obstacles; braking zones; you know the road surface etc). On the street you might take a turn on a winter day and have sunny/shady spots (sunlight between the trees). If you need to brake hard, the abs system will allow each individual tire to maximize the available grip while still letting you take the turn as much as possible. There is no way anyone could do this in a non-abs car. I drive a car with no abs too but i like to think i am aware of it's limits. If it is not completely dry outside i am a lot more cautious because of potentially hazardous situations (animals, idiots etc)

I've seen tests where non ABS outbraked ABS, but it's only under very specific conditions. Most of the time, ABS wins hands down. Having driven an old swing axle Beetle a lot, I generally consider braking while in a corner to be a big no-no. I still carry that habit with me - slow down before the corner, not in it. I'll only brake mid corner if absolutely forced to.

What is a „M135i Competition“ ?

That’s a very good question, for which purpose are you looking ? Pure street, pure track of mixed use?

@@vollcare4076 Thanks for your answer! Some Road, 100 laps at the Nürburgring Nordschleife and some Trackdays

@@slaier57 well, one pad can’t be really really good in both road and (GP-)track at the same time: - MX72 perfekt for road, good for NOS, but will fail on GP - ME22 ok for road (maybe some weakness when really cold / initial bite), very good for NOS and good for GP - BMW MPerformance: Very good for NOS, good for GP, 100% road legal but they produce noise

You still have to upgrade the brakes if you want to track your Porsche, i recall of a class friend whose father had a 911 CS and went to Magny-cours F1 track, his brakes lasted 1.5 laps, next time he went with upgraded pads and fluid.

@@MrTchou 911 CS, which Modell is this? 1987 G-Modell ?

@@vollcare4076 the one from 1989 yes the Carrera ClubSport which was a limited serie if i recall correctly. It was supposed to be « track ready », suspension was tuned, it was lighter than the normal one, they stripped it from a lot of equipment etc…

Did you get a resolution or diagnosis for this?

@@dielaughing73 they blamed it on ‘pad material stuck to the discs. Then I finally made them do a run out check and they said they were ‘in spec’, despite the runout being over 3x higher than what f**king Hyundai would consider enough runout to warranty claim on. Gave up, I couldn’t afford the silly high prices they were after for discs. Don’t have the GR anymore but I’ll definitely get another in future.

@@Jonathan_Doe_ that's crappy. If a company makes a "performance/track" product they need to stand behind it. It's literally a matter of life and death sometimes

Nope, on snow for example you stop faster by locking the wheels, it will aggregate snow just before the tyre, and this little bump that was built up acts as a stopping device on the wheel, ABS won’t allow for this to happen. ABS role isn’t to stop faster anyway, it’s to keep directional control of the car, allowing you to avoid something instead of sliding into it.

​@@MrTchou I should have mentioned that I meant only high mue friction surface. On high mue, latest generation ABS is the way to stop the fastest. ABS not only lets you stop faster but also keep steerability. You are right about low mue. On low mue, with the snow accumulation method during sliding, you do gain a bit in deceleration but you completely lose steerability.

​@@scenicswissdrives1264why would we be comparing abs in a situation that has plenty of traction? Are you trying to tell me I'll get the best braking on a dry racetrack by locking up my brakes and letting ABS take over? Because I seriously doubt that

This comment would be helpful if you explained what’s not correct in the explanation.

@@MrTchou brakes are a rabbit hole, so it's not easy to just simply correct what they said because even the explanations and validation are off. You are essentially asking for 30 minute discussion on brake lines by themselves to be condensed into 3 minute read. To be quick and reducing wasting my time further. Factory lines don't bulge until they get old. Only on a test bench are braided lines stiffer. Braided lines need to be replaced every 2 years because they don't pass any requirements for a road going car and their coating fails and let's dirt into the braiding. The rubber coating is superior because it's more resilient on corrosive environments. This is why braided lines have a silicon covering over the braiding to stop dirt getting in and putting holes in the Teflon. In a lot cases, OEM rubber lines are more expensive to produce than braided lines by companies that self certify. Unless it's an actual racecar, not a streetcar or track car, it's better to replace rubber lines on the 5 year schedule which is when they might start to deteriorate from high track temps. All this information is backed by companies like StopTech and OEMs in public marketing or direct conversations with brake engineers. I'm a brake nutcase, and it needs to be called out that what is shown in this video should not be taken as fact. Further research is needed before "upgrading" the car. Brake lines are 100% controversy topic, but it's only because of misinformation like in this video keeps getting repeated.

@@MattGreenlandaren’t braided lines just regular rubber brakes with the braided stainless steel over them so they can’t “expand”?

@@piovo5222 No. The reason why they need to be replaced on a shorter schedule is because debris gets in-between the braid and puts a hole in the Teflon, super common. "Good" braided lines have an additional Teflon layer to protect against this, but those breakdown quickly in the elements and need to be inspected frequently.

The new M cars have amazing brakes, I track my F80 M3 on stock calipers with upgraded pads and rotors and its perfect!

Nurburgring is not THAT demanding on brakes to be honest. so for this use case, the stock blue caliper works fine (assuming you have high temp fluid and track pad). But on a more demanding track such as Laguna Seca, the stock brake just doesn't last.

@@jim1013yyf yes I agree, Laguna Seca is one track that will kill stock brakes.

Interwebs says a lot of sh@t also… about a lot of things.

@@MrTchou haha some of those are. but some others just have different use cases, hence different requirements

Those are the basics.
