Left Foot Braking Explained
HTML-код
- Опубликовано: 11 авг 2013
- Quick explanation of Left Foot Braking filmed on site at the Team O'Neil Rally School. Left foot braking is useful for any race car driving and for daily driving on the street. Left foot braking is critical for rally car driving more than other racing because the drivers are constantly managing road speed, understeer, and oversteer. Feel free to post any questions or comments, we'll get to them shortly.

Left ear hearing:D
Grilledcookie my headphones broke and only play the right channel!
lmao
7.1 sound ftw
jokes on you i am deff in my left ear so i switched my ear buds and it is right ear hearing for me
I only use one earbud, didn't even notice till I saw the comment.
Me: left foot brakes
Friend: is that a tooth in the steering wheel??
I have no fucking idea what you're talking about
Matsuda u idiot
speaking of the left side, my left ear enjoyed this video
I moved out a bit to the countryside several months ago and watched this video around about that time too. Part of my daily commute involves several km of twisty dirt road as well as some twisty tarmac sections. I started practicing left foot braking on my way to and from work each day and I am glad to say it has now just become natural to use my left foot to brake and slow down or balance the car through corners on both surfaces! I have started implementing it when I go to the race track too and am finding new levels of car control that were previously a mystery! This video really helped me though, particularly the tip about keeping your heel on the floor when starting! Prior to that I would always apply far too much brake force when I tried it.
Swap headphones around for right foot breaking.
Next up : Right foot shifting!
Right hand shifting (by that I mean pressing the clutch with your right hand)
Then cross leg shifting
Putting your foot on the shifter to change gears while your left foot operates the clutch
Left hand shifts the gears and right hand does the turn signal
handstand shifting and left foot steering
Pro tip, left foot braking does not work on a motocycle xD
except if its a pre 1975 british motorcycle
people stableize the bike with trail braking the rear around corners, but you're right, its right foot :'D
right foot trail brake technique for the two wheelers out there ;)
Yeah you gotta drag BOTH feet.
it does. you just have to commit and really put the foot down
Really fantastic and helpful instructional video! I'm also extremely impressed that this instructor did the whole thing without fumbling his words, doing the wrong thing with his feet vs his talking points OR having to make a single cut. Really awesome stuff. Can't wait to practice this in my Honda Element while we finish building my SI lol
I might have missed it, but what's important to remember is that modern cars often cut the accelerator signal when the brake is pressed and thereby rendering the practice exercise futile.
Thank you for the video.
LFB provided a huge improvement in my car control confidence.
I could not race without LFB.
That mic has an amazing amount of notice cancelation for outside noise. Is that what they normally use in car racing?
Depends on your team's budget ;D
You can use gate in the signal flow with a cheap microphone
tried this without realizing it was a thing last night, and after i whiplashed myself, ill be trying it again...
5 years later: you manage to get it down?
Lol yeah kinda curious to
@@SpaceMissile she died the second time i think
This Video helped me a lot... thank you for these great tips 👍👍
I've tried this a few times on the road course during HPDE events. I like the idea, just need to practice more. thanks for the video.
Always make sure you wear a helmet if your gonna left foot brake!!!
LOL - and do make sure there's nothing behind you first, as your left foot is used to de-clutching and you'll end up stamping on the brake like it's the clutch..... I tried it once, and if it wasn't for my seat belt, I would've gone through the damn windscreen.....
truthpig haha happened to me as well haha
Sometimes my left foot is catching the break a little bit as well as the clutch and this is funny (but not int that particular moment, absolutely not). Also I sometimes press the throttle a bit when breaking and have a motor spinning a little bit faster than idle which sounds strange for a second or two until I understand the reason. And no, I don't have Alzheimer (yet).
@@truthpig at I started driving I always braked with my left foot because I thought it was the right way to do and then my driving instructor was like: what the hell are you doing?
@@truthpig 🎵_aaaaand that's another reason why we always wear our seatbeltsssss!_
😋
Nice explained! Thank you! I`m glad you used a car with a lower acceleration pedal.
Very helpful! Thanks!
Very helpful video, thank you very much! I'd definitely take some courses at Team O'Neil if I didn't live on the other side of the U.S. ...
I thought left foot braking was all about weight transfer in fwd cars in order to turn at speed, and keep the power directly over the front end..
essentially what he's showing you. for a corner he left foot brakes to shift the weight of the car over to the front so the back end is light and rotate around easier.
awesome video
Had a better time learning the pedal feel on an automatic trans first. The switch to the manual went way smoother. Try it in an open lot , you may come to a screeching halt the first few. It also helps to be proficient at heel toe before you try as well as double clutch shift but I only really double in older cars, but every once in a while on my STi.
*_Excelente vídeo_*!
I tried left foot braking today in my moms car, also a ford fiesta and i got abs straight away lol
Great ! Thanks !
I agree with Billy Elliot Mann as I too would like to see a full speed run and how that looks when at speed. I also would like to hear the engine/see the tach so I could get a feel for how much engine braking vs load with the brakes affects the car. Maybe a similar video with interior and foot cams run at speed with engine sound and with one run done with no commentary and the same run again with commentary. Great to see and hear the instruction and thanks for putting it out there.
Now try right foot clutching
X-maneuver
Zaahaha
Youre gonna like their newest video
very nice video of left foot breaking, i drive a FWD car (acura rsx) and my friend alwasy told me to learn left foot breaking for tracking/racing, very good introduction to it and very appreciate the help of learning it, ima start doing it first thing tomorrow morning to work :)
Thank you.
Thank you for this video! I apply LFBing at all times, and shift without clutch when appropriate. I lost a wrx and have an automatic now. Left foot breaking in an automatic is the only escape from my emasculation! In a real car (standard) the transition from LFB to RFB is almost a process of logic if you need to clutch. It did definitely make me very neurotic about civilian drivers breaking through turns when they should do all of their breaking before they go into a turn! I also get irritated by people taking Corners at 2 miles per hour like their car is going to flip if they went any faster, but that is a completely different story. In the end, if everybody drove like they knew how to Rally then everybody would drive way better and there would be no such thing as a traffic jam
That was a very touching story
Very nice! There will be other videos like this? Looking forward to!
Just practiced that with my old corolla today and I noticed progress by the end of the day when I'm driving back from work.
I am a fast learner in terms of driving XD
I haven't felt this excitement for a long time.....
I shall practice it with my old corolla for tomorrow and then move on to training it on my Camry.
How does left foot braking affect the torque converter in automatics? Does it cause damage over time or is it perfectly safe assuming you aren't pushing the TC to the point of stall?
i agree LFB is a good technique, but it needs real practice to be used on street, and i think it's more appropriate to be used in street cars with AT trans just like in karts, F1, and rally (rally in particular as brake bias is on the rear), the thing though with LFB really is it creates confusion - your brake lights keep lighting - with other drivers (as they may not really know if you're braking or what) on street and may cause accident. I drive normally on street but i use LFB in karts and race sims, i really think LFB is best left in racing on tracks
Would be nice to see a run with the foot cam "flat out" through sections of the school. It's good to hear the audio and slower speed for instructional purpose, but it would be nice to have a view showing the feet and hear the engine at full clip. Gives a good view of how things are done at rally speed.
Can you do a vid about fast gear-shifting?
I learned to drive with left foot braking, even passed my test with it , I can honestly say that it's safer , and you can be a lot quicker on a track day .
was this a race license test or public road test? Just curious
@@chrispewpew theres no way this guy was left foot braking on a PUBLIC road test.
The sounds transmits to my brain even from 20 feet away
Awesome
I remembered I heard about left foot braking while driving on the highway with slow traffic, so I just tried it for the first time there. I almost locked the wheels at 90 km/h and not far away from other cars. I didn't try it again since then xD.
i have no idea why i am watching this but i like it, i have never had a car to start with
It will still be "mono" but you should be able to duplicate the left side audio track onto the right side as well, with Premiere or Vegas.
Great video! I'll be putting it all to practice as one of the lead cars at Ojibwe Forests Rally next week!
who cares
first tip: yeah hahaha exactly what i did when i first tried left foot braking, felt the car slowing down too fast and instinctively pushed the brake it in all the way trying to put the clutch in. Would of looked like the dumbest shit just slamming on my brakes and stalling out of nowhere.
me 2 just yesterday
Been there, done that. good thing i was just in front of a red light so it looked like i stomped the brakes and my bmw turned off the engine (you know the newer cars do that, mine doesn't, tho)
Seems so easy looking at this pro.... =)
Ian Meyer crossfeed and you're golden ;)
For me it's uncomfortable physically. I'm working on it but up in my inner thigh groin area hurts from doing it and on the outside of my left knee.
I've been using a empty parking lot to practice.
My shin hurting too. Idk I think my placement is wrong.
so i skimmed the comments and didn't see anyone mention why you might even want to left foot brake. in a FWD car it lightens the back end, makes for a sharper turn in or can help swing the back around. same for AWD just not the the same effect since theres still power going to your rear. in a RWD car only thing i can imagine is it would allow you to keep you revs up while exiting a corner. and for all 3 if you have a turbo it helps keep it spooled up on the exit. basically all used on tracks/off road course.
All cars will weight transfer forward when braking (as you said, lightens the back end), regardless if they are RWD or FWD.This gives more traction to the front tires, which are doing the turning. Lightening the rear will cause more oversteer, or like you said, sharper turn in.
If you brake with the right foot, you are wasting time getting back on the throttle after the apex of a corner. The amount of time it takes to remove the right foot from the throttle and move it over and onto the brake pedal (and then back to the throttle pedal) will cost you precious time. You can accelerate quicker out of the corner if you left foot brake going in. With left-foot-braking, there is no lost time; the transition from throttle to braking is immediate. (Source: Ultimate speed secrets by Ross Bentley)
After working up the necessary sensitivity in the left foot (kart racing will help with this), left-foot-braking will also help you drive smoother. It allows you to alter speed without upsetting the balance of the car as much. This means that you will not go beyond the limit of traction of the tires, going into a slide or spin.
I really recommend the book I referenced, if you are interested in racing any sort of car in any sort of race!
Lennart Nilsen which book is that?
i skimmed ur comment, and ur an idiot
Denny Dubs in rwd you can use it to control some slip into the car. if you watch the OG Japanese drifters they use a foot brake feint to drift and hardly ever use the e-brake. you can drift really close to people by using the throttle and left foot braking to keep the front and rear of the car in check. touge and rally would see rwd benefits in left foot braking because some slip may be necessary.
regardless of drive setup, wven rwd benefits , when you can acheive proper slip angles around a corner given you modulate it correctly, on tarmac or in dirt
Paxton, do you have both speakers hooked up? I did notice that the audio is left speaker only on this video
So you can shift the car without using the clutch when its moving in a stock transmission or do i need some type of shift linkage to make it work?
If i have muscle memory when emergency stopping can i still use left brake?
I have always left foot braked, and once it came in handy. I was driving on a two lane highway one night and a cat ran out in front of me. I didn't think much about it until I saw a dog coming out of some bushes next to the road. The first thing I did was brake as hard as I could with my left foot, but when I realized I wasn't slowing down fast enough, I put both feet on the brake and pushed through the ABS. I stopped with about 6m/20ft before the dog (which by the way was a huge white german shepherd) but thankfully I stopped before anything happened. I was the only one on the road and ever since I was getting lessons when I was 15, I have always left foot braked. I have tried right foot braking and all that happens is I don't know where the contact point is with the brakes, so I am overaggressive with them. Ironically, I am forced to drive automatic since I have no car of my own.
is that good to use left foot braking in FWD, incase of braking and throttling meking more load on power transmission and brakes???
🤔
I'd like to see a heal and toe shift video
That's a very important thing what he's talking about: get used to L foot braking first to feel the braking force...
I remember when I've been trying the stuff in my previous car which was less sensitive on brake pedal and once I tried it on my another car I had the hard braking memory 'in my L leg'... I tried that for the first time on the car in fairly slow moving traffic intending to slow down just a bit, but It really surprise me that I brake really hard and the traffic begind me was really surprise - they could crash into me...
It would be my fault in my opinion, but insurance companies always think opposite ^^'
The best advice - try it first off road.
About left foot breaking. Lets say I have to emergency break, of course it will be faster but don't you need to also apply the clutch?
I drive a 2019 Subaru STI and I find that when I left foot brake the engine power cuts out. Is there a workaround or some way I can disable this function on the car while still keeping it road legal?
Am i right that right braking makes the rear wheels slide on curves and 45 degree turns while pointing the front to the road where it goes.
Jingo Lopez you can brake with either foot to initiate a slide and get the car pointed at corner exit. the difference would be if your going for a huge inertia style drift vs a quick turn in.
Amazing tutorial! I want to know is modern normal street car can shit without clutch?
You shouldn't
when he says clutchless shifting in normal cars, I assume he's talking about synchronized gearboxes? I know a crap ton of forums with people talking about it being ok, or its wear on synchros, etc.
And of course rally school people tell us its nbd :D
How to shift without a clutch in the most appropriate way?
when should you left foot brake? should i use it everytime in a turn? or when you feel like you are understeering and too fast into a corner?
Does left foot braking damage the car at all?
also on my wrx the clutch and brake pedals are really close and makes it hard to do that. Do you guys have that experience?
Yea I think that’s on most cars, being that there has to be 3 pedals instead of 2
LOL I always left foot brake when I'm doing a rally sim, so when I tried doing it in real life, I realized pretty quickly thatin racing I break very hard, so I really had never had the experience of just slowly at using the brake pedal with my left foot. When you're on asphalt in a Toyota Camry, slamming on the brakes doesn't really work very well.
what shoes are you wearing??
Is there a reason the audio is only playing through the left???
Kyle Milford because he is leftfoot braking obviously
I left foot break in my work truck because I swear the pedal box is weird and tires out my right foot driving all day (pedal box too far left of seat)
I learned to left foot break before I learned manual, never had an issue pressing too hard bc of that.
James Hewitt I learned to drive manual and to left foot brake at the same time, it's so easy, i don't get why people are getting confused with it
ブラックピットDark Pit i drove both manual and automatics learning to drive and found it was an easier learning gap to learn left foot brake modulation without having to think of switchin g left foot to clutch deing shifting as well as the wider brake pedal, now that I don’t have my manual tranny anymore, gotta wait till I get another one to get a better feel again for it
There's no reason to left foot brake
I'm gonna try and put this into practice. I just have one question though. Does clutchless shifting do any damage to the clutch or trasmission or any other parts to do with the drivetrain?
When you get it PERFECT no it does no damage, but even the best drivers don't get it just right every time. If you can, practice in a $500 car or something until you get really good at it first. Somebody else's car, a rental car if you can find a manual, you get the idea haha.
how did you disengaged the brake by wire:))?i want to do that to my car
Is this car common of American cars? I find it interesting that your driving position is on the other side of the car to us over here, but the pedal arrangement appears to be the same, i.e the clutch is the left pedal, then brake in the middle, then gas on the right?
Great video! Is this the car with the loud exhaust? I remember that being the only one without a rearview mirror, and the one I used to get the best time in the rallycross final exam. P.S. still haven't received my hat prize in the mail! :(
My car's DBW cuts power after a few seconds of prolonged LFB. Acceleration is also blocked for a short duration. This is very dangerous...
What's your stance on right foot heel toe braking then switching the left foot to the brake as you go through the corner?
Sounds great!
Side of foot shifting? I've heard the correct term as Toe-Heel Shifting. Figure it as "point your TOE on the brake, pivot your HEEL on the throttle"
What if you can't do that
Very well presented and explained, but the actual benefits of LFB were ignored. Also, why LFB then return to the clutch to downchange, then return left foot to the brake. What's wrong with a single application of the brake, with whichever foot, then the downshift, in the traditional fashion?
How to create road rage?
You'll be fine. I've beat the crap out of a lot of cars with automatics and put well over 100K miles in a couple mixing left foot braking and back in the day even power braking them. I have never had a torque converter fail on me. Automatics are easiest to learn in because you don't have to worry about shifting. I always make it a point to strictly left foot brake anytime I drive an automatic. You may go through brake pads a little faster than normal when learning to overlap the gas and brake.
Knox is the man
lol oh no he tossed a heel-toe in... time for another video for all the "WTF's" great video guys! shared!
I really can't watch when the sound only comes out one speaker.. makes me feel sick.
this is a lot of work for one video that came out four years ago, but you can use your audio hardware sound settings to set your speakers to "mono" instead of stereo and it should make them both play. You'd have to turn them back after though, or your videogames and music will sound weird.
Thank you for a prompt reply<
Is there a technique or a formula for specific outcome, Sort of like aiming for the apex and trail braking is used with FWD for example>
To where left foot braking would be more beneficial in a situation A but not B in a different drive train?
Yes there are a handful of different techniques based on what result you're trying to get, and it's pretty different in a FWD versus an AWD or RWD
Team O'Neil Rally School thank you
Hi!
Very good explanation, but i still don't get why you would need to brake with your left foot?
What are the advantages?
in my opinion I only use left foot brake in turns. you can stabilize your car back in turns or dirft. i think in normal streets you dont have to use it. I only do left foot brakeing in rally training on a speed stage. Its only important if you are a rally racer or a drifter(but drifters mustly use handbrake)
I can already do everything you showed in the video. I'm just not exactly sure how you use the brake against the throttle to make the car slide. Not sure how and when to apply the brake and why that makes the car slide... is that a lift-off over-steer type thing where you get the slide after because sometimes it feels like braking against the throttle just causes me to understeer, like when I'm in the snow.
It seems to me, and maybe I'm wrong, but this is really not an issue on RWD cars, it's really more to balance a FWD car and to cause the rear to slide, if you flick the car into the corner, use lift-off oversteer or have a RWD car, this doesn't seem to be an advantage, unless you want to move more weight to the front.
Can you please explain the no clutch shifting please? Especially the downshifting. I see you use the throttle. Is it like: turn the gear off then short throttle then turn the down gear on when rotation speeds are in sync?
So the up shifting is just releasing the throttle and switch the gear off at the same time while the gears have no load (a really short moment) then wait for the motor spin to slow (1/3 of a second) then turn the up gear on.
Do I understand the idea correctly?
Is it ok for the gearbox and its synchronizers?
We did a video earlier, this probably explains better than I can here in text: ruclips.net/video/CwqVTikzOp4/видео.html
I have a question and need your opinion. Left foot braking increases responsiveness mid turn, so in theory it has a similar effect as an LSD would have? The torque and braking limit slim in a way... What is your opinion on this?
Left foot braking definitely allows you to control your wheel speeds much more precisely.
If you're only using the gas on a slippery road, it's easy for an open differential to spin one tire (usually the inside of the corner).
If you ride a little LFB in the same situation, it doesn't let that tire spin so it's exactly like you say where it acts as a limited slip diff.
while road racing i get alot of understeer ima try this out to side my ass out a lil bit more might also shave 6 seconds of my lap since theres alot of corners at the track i go to
How'd it work out
Why don't I have any audio?
If you're in an emergency stop in traffic, wouldn't you stall the car from being in gear, or are you expected to be lightning-quick in putting the car in neutral before hand?
you can pull the shifter out of gear
I only do left braking because of be left footed I only use when shifting now.
Advantages and Disadvantages of this please?
Looking like a tool
Does it cause faster wear and tear on any of the break pads/rotors, drivetrain or throttle body?
You'll potentially go through brakes a little sooner if you're driving aggressively, but nothing new there
Trying to learn how to do this to drive faster
gdi just b/c it's about left foot breaking doesn't mean you have to only use the left audio
No Audio?
It's the case in all modern cars I've driven and tested this with. It could be that it's part of the legislation where I live (Europe). Also, being a qualified mechanic and studying automotive engineering I know what I'm talking about. I have tested this in diesel, petrol, (semi-)automatic, manual, you name it.
So it could be different where you live, I don't know.
Keep in mind that this isn't the case with vehicles which have a physical cable connecting the pedal to the engine.
I know that Nissan's have brake override technology in case people stomp on both of the pedals in a panic situation. I wish there was an option to turn that off. Thankfully, I have not experienced it in a Subaru.
please during braking with the left foot, how to properly maintain your body (without using the toe clip)
Thank you and good luck
I practiced left foot braking in traffic for a week and I wouldn't even realize I was braking with my left foot it was like I've been doing it for years. You just have to take your time to unlock the other side of your brain. But like he said practice before taking it to the dirt and gravel.
I need to learn how to unlock the right side of my brain lol I'm Left footed so all my muscle memory is on my left Side...I can't Drive only using my right foot.. So driving automatic I use Right for Gas and Left For break 😩 that's the only way I can
How do you shift without a clutch
Make sure there is no load on the drivetrain, match the rev and shift.
The problem is, when im in a right turn and i left foot brake, then i don't have my left foot for support and i kind of fall over to the left side..
That problem goes away with good bolstered seats and belts, but yeah it's an issue in a lot of street cars.
I tried it once, I nearly smacked trough the windscreen. Likely no one was behind me :D
