I'm just a noob playing F1 '21 on a controller, and this helped me so much trying to drive without assists. A simple tweak of 50%->58% brake bias, and all of a sudden I can trail brake competently! What a revelation, thank you!

[@dannyleeracing]

Awesome! So good to hear it's made a difference, you're exactly the type of player I wanted to reach. An 8% shift in bias is huuuuuuge, so it must've felt like a bloomin' ice rink before!

[@manbok2035]

Thanks, this video helped a lot! I always played with heavy front bias, up to 70-30 front as it helps with turning in.....but then always wondered why everyone else was able to slow down much faster. And for a while I didn't even consider how brake distance is related to brake bias. I have learned to drive with a balanced brake bias and without rear lock. Basically, you need to brake a lot harder initially and then have a shorter/less heavy trail braking as the longer you trail brake, the more the brakes heat up and possibly lock up. For each track, you need to find the limit how much to brake and how much trail braking you can do without rear lock.

[@excrubulent]

I'm way more into offroad racing than track racing, I'm currently headachey and tired and at the start of this video this sounded like something I really didn't want to do, but damn it you made a really good case. I think I have to try this.

[@AHStrongsville]

This is eye opening and one of your best videos. Thanks for putting this together.

[@THIS---GUY]

Thank you for the excellent explanation. I ignorantly only adjusted brake bias to compensate for the engine placement and left it there and adjusted to how the car felt.

[@angryginger791]

Just wanted to say that I love the livery with the dimensions on the white car you used to show the brake balance. I work in modeling and drafting for an aerospace company, so it gave me a chuckle. Great video. I've never adjusted balance from corner to corner, only to get it good enough to be stable in all corners. I've hit a plateau lately so maybe this will help me find some time.

[@kristaps2010]

i found this info really useful. it's not a secret very fast racers always use a setup. i want to be faster but did not want to blindly follow somebody's setup without knowing what it is and how it works (what it does to your car). With setups it's too much to take in, too many options to adjust. Brake bias was always nb1 mystery for me, as I heard a lot people use it, it's used more than other adjustments. Now I understand what it is, how to use it and how crucial it is to improve lap times/it also makes easier to manage the car. Thank you

[@mrtom2450]

Thank you Danny, I’d only ever tweaked BB at initial setup and hadn’t thought to adjust on track. Really useful video!

[@jopvandam6820]

There´s one thing I don´t quite understand. As you come up to the ascari chicane at 5:38 , you mention you want tick the bbal down a little bit because you want some extra turn in, but earlier in the video you said you'll want a little higher bbal for trail braiking into a turn. That sounds contradictory, isn't trail braking what you want when turning in? As in how does decreasing bbal improve turn-in when it makes the car more unstable under braking?

[@extremeencounter7458]

Because if the bias is too far forward, you'll essentially be getting understeer and won't be turning in with the proper slip angle. All he's saying is lowering it can increase turn in when needed, obviously since there's varying levels of bias required for each turn, you'll have to turn it down at some point.

[@jopvandam6820]

@@extremeencounter7458 I’m sorry but I still don’t really understand… Is front bbal good for braking while turning? Or rear bbal? From what I understood from the video, if you’ll do hard braking in a straight line you’ll want the bias to be more rearward, so how does that then also improve turn-in? Maybe I’m stupid but I just don’t understand 😅

[@extremeencounter7458]

@@jopvandam6820 Think about, it you just raised the bias so that you can trail brake a longer corner, you’ll have to lower it so you can A) brake harder on the next turn and B) keep you from under steering on a sharper turn. Remember how the rear steps out when you lower the bias? The opposite happens when you raise it, meaning the front of the car will hug the ground, but too much will make it under steer. Lowering it makes it easier to allow the rear end to rotate out, but too much rear bias and it slides out. But if you just leave it high, the car will understeer, meaning you can’t turn in on a tighter corner

[@Mckorzi]

[@mattm1634]

Do you know if it's possible to change the magnitude of a change per click in iRacing? I have a rotary encoder but it changes the bias in 0.1% increments which means I'm turning it two full rotations to go from 52% to 54%...

[@dannyleeracing]

I don't think there is - sometimes the bias increments are specific to each car, I saw somewhere that someone has to click an obscene number of times to change the bias to one end of the reasonable operating window to the other. Stick a suggestion in the iRacing complaints/feature suggestions forum, I would.

[@silviutudorescu8114]

yeah same here by the time you chage it to 1 full degree your like 3 corners later

[@dannyleeracing]

Cheers man, I appreciate the feedback. The formula should never change.

[@nvstewart]

Brake bias is important enough for not just Renault to do auto bias control, but also McLaren putting a 2nd brake pedal in their 1998 F1 cars linked to the rear brakes for the drivers to manually control bias on the fly.

[@4WDBearAus]

The second brake pedal was linked to either the inside or outside wheel (depending on the track) to assist with turn in, not bias.

[@jeremyleemartens801]

It only controlled one rear brake per race for additional rotation

[@damiengvideos4337]

Great video! I'll finally make use of some more of those button on my wheel!

[@hellomihai]

Quick suggestion. Instead of writing % for corners, have a baseline number and save the delta +1% t1, -1.5% t2. This might be less confusing to users who don’t realize or skip the info about different cars have different baseline balance.

[@hellomihai]

When changing cars you just need to update the baseline number and likely the deltas should be spot on.

[@MikeSwannick]

The brake bias changes in Assetto Corsa are in 0.2% increments (I think). I have it bound to a rotary encoder on my Ferrari wheel and for some changes of around 2% your thumb is just a blur. They need to make the incremental change editable on a car by car basis.

[@dannyleeracing]

Just another challenge of sim racing. Maybe there's a standalone bias adjuster available, like the real thing? I'd actually be interested in that.....

[@Calbac-Senbreak]

Whenever it makes you lose even a little piece of focus, it's no longer worth it. The sensibility with the brake pedal on the braking zone makes all the difference, as a bit of mistake in that regard could let you in trouble (with tires temp) or see the braking efficiency going out

[@dannyleeracing]

Like anything new, when you initially introduce it, it's tricky, but soon it's second nature and is a benefit to know. I definitely needed it in some endurance races recently as the car got twitchier and twitchier as the race drew on and clicking it forward just a little brought all the confidence and stability back.

[@Calbac-Senbreak]

@@dannyleeracing Yeah, endurance is one of the best targets to apply this method, indeed, and I agree that there are more benefits than disadvantages for using it on this referred racing mode, while it is more important maintaining the pace stable than being extremely fast in a few laps. Nonetheless, as I've mentioned before, the 100% focus spike in the brake pedal modulation is quicker for sprint races and hot laps, unless you're gonna change the brake balance only one or twice during the lap.

[@testdirver]

this work great for me and should be explain with trail braking together after this i gain a full second and the best didnt spin in brooklands

[@dannyleeracing]

Awesome mate, glad to hear it. I did a run of Ferrari Fixed GT3 in iRacing recently and at default bias I was having real trouble. After shifting it more to my liking it was much better, though the fixed setups still drive like sheds to me.

[@chopperbristow]

So Ive never played with it having only done fixed series and not realising I could use bb. Currently doing Ferrari fixed so not a lot of time for fiddling especially with the smaller tracks. Did some testing at La Guna Seca yesterday and dialled down the bias which was better stopping power and felt settled all the way around. I didn't fiddle once I was driving and found half a second instantly.

Thanks Danny, never actually thought of it like that. This is why iLMS this week at Sebring is going so bad. Keep locking up into the chicane, and losing the back elsewhere. Any comments on changing with fuel load?

[@dannyleeracing]

Sebring is a fantastic example of brake bias being key to setting great race pace - if I don't tweak the bias forward a bit I find the last turn REALLY dicey, and if I don't tweak it back a bit for the deep braking zone into the hairpin I often lock up. It only takes one screw-up to start a whole chain reaction of mistakes so reducing them is always worthwhile. Fuel load burn off affects different cars in different ways - fuel burnoff and tyre wear affect the car and sometimes I find the car is twitchier the lighter it gets, I more often than not offset the bias forward one or two steps when that starts to be the case.

@@dannyleeracing you got a shout out from Matt malone. They were talking about slip angle in his chat and mentioned yr vid

[@timbuktu6730]

I haven't really adjusted my brake bias on the go but I thought it was the opposite. For big braking zones like at the end of the Monza straight needs lots of front bias because all the weight is on the front tyres like hard braking on a bicycle in a straight line. And to trail-brake we'd need to reduce the power from the fronts to get it to turn in more effectively. I'm surprised how close to 50 50 the bias are too. Thanks

[@dannyleeracing]

The 'default' amount of brake bias differs from car to car based on many factors, including weight distribution and the actual leverage/effectiveness of brakes at each axle. So in a front engined car the bias will be further forward than a rear engined car where most of the weight is at the back. That's the tricky thing about brake bias, it's not one size fits all, which is where the practical observations come from that you can only get by practicing and seeing the difference it makes. Try it for yourself and you'll find yourself experiencing less lockups and spins, at least in cars without ABS the difference is certainly felt. If learning to think about bias means you avoid just one front lockup into Monza T1, it'll have been worth it, and that's often the difference between keeping a place and losing it.

[@timbuktu6730]

@@dannyleeracing Cool I'll get testing. Thanks for the reply

[@dannyleeracing]

@@timbuktu6730 Hopefully it makes a difference dude, in iRacing at least it is sometimes a lifesaver, on some tracks I find happiness with one settings and on others I can squeeze more out if I do tweak it as I go. Over a race distance sometimes the car gets nervous on older tires and I move brake bias forward slightly to manage the back end.

[@TyronDeakin]

[@SufferingAddict88]

I would like to add that just to get people into considering brake-bias at all they should at least do some practice sessions where the fiddle with the pre-set brake bias.

@@dannyleeracing your welcome Danny, you KZbin simmers are an amazing resource. My biggest weakness is breaking and more importantly getting the turn in to slow tight corners like turn one at Monza. This is where I think changing the bias and inducing a little oversteer will help.?

[@dannyleeracing]

@@splitenz1770 Yes it will - in any corner where I feel like the car has understeer it calls for a shift of brake balance to the rear. Try decreasing bias little by little for corners like Monza T1 until it feels like it has the turn-in you need, then you know that Turn 1 is best taken with 'x' amount of brake bias and you have loads of time on the main straight to set the bias, then loads of time after T1 to put it back to normal for the rest of the course. If the car has understeer everywhere then you're looking at a different problem.

[@raphaeltaormina7418]

Could you please comment on the effect of weight transfer? On a hard braking zone the car pitches front and is more loaded than the rear so there's more grip potential there. It seems counter intuitive to be at 49% bias at T1 in Monza given this effect... also I understand the stability factor for trail braking but you will be limiting your tuning potential while trail braking with a front bias because the tyres are asked to do two thing at the same time so thats where the rear wheels can help with a bit of extra trail braking. Just wanna hear you thoughts on that, great video :)

[@raphaeltaormina7418]

Turning*

[@dannyleeracing]

The key thing here is that the brake bias values we're talking about here are in a really tight window, like 1%-2% variance. Also don't pay too much attention to the values on screen as they differ from car to car, sim to sim. The Ferrari 488 is mid-engined so will have more weight balance toward the rear tyres than a front-engined BMW M8, for example, and this is reflected in the 'operating window' of brake bias that you find. Weight transfer is absolutely hand-in-hand with brake bias. If you brake in a straight line you can afford to use more braking on the rear wheels because you are not unloading either side of the rear axle in the braking zone and won't risk locking a rear and spinning out. Whereas if you are braking AND turning then you want to shift the balance towards the front to avoid spinning out. When you have a well-practiced lap and you've tweaked the brake bias per corner (if necessary) to be able to hit every corner in every lap reliably and without nerves, that's what will give you better results over race distance. If you're in any way interested in all of this then the Skip Barber book is absolutely the thing for you: amzn.to/33Jzulv

[@chuckystang]

What would be more helpful in iRacing is if you could actually press the brake pedal with more authority without locking up. Anyway to adjust the amount of force in game? Anything more than breathing on the pedal in any car and it locks up.

[@dannyleeracing]

You can only really adjust brake pad friction and master cylinder size etc from the garage settings. When calibrating your brake pedal you'll also need to make sure you're pushing it HARD when it's figuring out your pedal range. What pedals do you have?

[@chuckystang]

@@dannyleeracing Thanks i found in iracing it makes no difference how hard i press the brake when calibrating. I have fanatec v3s. I can manually adjust min and max brake pressure within fanatec software but would be nice if i could set the max pressure in game to be much higher. I have no luck trying to do so thus far... For example you can easily do this in titles such as Rfactor2 & AMS2, etc

Thanks again Danny!

[@dannyleeracing]

Yes, generally speaking the same rules still apply but it's best to take the inspiration gained from this video to do some trial and error and see what works for you - if you need the car to rotate more under braking, you reduce brake bias, and vice versa - front wheel drive race cars tend to be loose at the rear because it helps them turn when the front wheels are simultaneously pulling the nose of the car, that's why you see front wheel drive racing hatchbacks sometimes doing a tripod around corners on track! They're built to do it.

so, basically slightly to the front when there is an opportunity for trail braking and slightly to the rear when it's too tight to trail brake, yes?

[@istachi]

Yes, think about it this way: If you're gonna have to trail brake, put it at the front. If there's no need to trailbrake, (like if all the braking happens before the turn), put it at the rear.

[@GabrielBoulos]

Great video! Does the brake bias also have that big of an impact for Formula cars on iracing? (Dallara f3, F4, SF Lights etc..). Thank you

[@dannyleeracing]

Brake bias has a huge effect on every car when trailbraking, the difference is in exactly how. In GT cars you can really feel the bias affecting trailbraking for a long time, whereas in Formula cars with a shorter braking phase and quicker turn-in, it's all over very quickly, but the underlying effect is the same

[@FoxRob93]

I cannot seem to ever remember how to adjust BB in IRacing and ACC but use it often in GT Sport.

[@andymaxwell23]

Great video, added to my list of ones to refer to as a bible! Quick critique if I may. The blue background'ed description of what the brake bias % means (at 7:54), could that be moved closer to the start of the video? Thanks for posting this.

[@majo2626]

Hello Dany, great video, i have a problem wih one corner on SPA, just after No Name, you have to trail brake down hill to the left, and back of my Boatley is verry happy there and i have problems taming it... would adjusting BB help? which way?

[@dannyleeracing]

Hey dude, sounds like you're describing pouhon. Love that corner, but it usually requires brake bias to be tweaked forward (increased) so that when trailbraking into the corner the rears are under less braking force and less likely to slip out from underneath you.

[@majo2626]

@@dannyleeracing thanks Danny, will try

[@rogerviana780]

Mais uma dica e vídeo maravilhoso 👏👏👏👏

[@DemonLordGamingAC0]

Well, I was the "I'll only drive" guy in GT Sport. I never cut corners (only one side on curbs at all times), I never used brake bias, I barely ever used fuel mixture, and especially, I never used cars because they were at the top 10, I didn't use assists besides ABS, and I accepted and removed penalties the moment I got them. As a result, I was a good pilot, but I wasn't "good" as in I wasn't winning. I'd be 2nd to 5th most of the time, sometimes 1st. Not that I cared however, I wasn't competitive and I never did FIA (and when I did I used a Countach when everyone used a small Toyota track car lmao) Edit: Since everyone in GT Sport used ABS because it's just too OP, I don't see the point of doing brake bias there anyway lol

[@istachi]

Lmao the Countach thing was a boss move. I'm assuming you won ;) Brake bias makes a HUGE difference in GT Sport, ABS or not.

[@DemonLordGamingAC0]

@@istachi I didn't win lmao, there was just no chance against a lot of these little cars. They were op, and hence why everyone was using them. I did beat some of them however lol

[@DemonLordGamingAC0]

@@istachi I would have used GT Sport without ABS, if not for the fact my brake pedal on the G29 literally only worked halfway... The other half that has the actual spring force was deadzoned, so I had half of a soft brake pedal for no ABS. Another one of GT Sport's brilliant balancing

[@istachi]

@@DemonLordGamingAC0 Hahaha, better luck next time, I suppose.

[@istachi]

@@DemonLordGamingAC0 There's really no point in not using ABS unless you can't use it at this point. I've always driven without ABS on GTSport.

[@gtrstreet]

Should't it be the opposite? LESS front BB in trail braking corners to release some of the front grip, and more front BB during straight line braking?

[@dannyleeracing]

There's so many variables it's hard to cut cleanly - too much front brake bias increases stopping distances, too much rear brake bias causes instability. There's a lot of ways to reach the right result, but the best one is to see what works in practice. If you understeer, decrease the % until balance feels perfect. If you oversteer, increase % until balance feels perfect. If you lock the front or rear during hard straight line braking, take bias away from the end that's locking until the balance feels perfect. The important thing is to be willing to try!

[@Chitown388]

ok, which kind of corners needs an increase of the brake bias? which kind of corners needs a decrease of the brake bias? and which kind of corners needs a neutral brake bias?

[@dannyleeracing]

Have a look at my updated brake bias guide! I do believe I go into that, worth a watch anyway! kzbin.info/www/bejne/rH6oaX-Cl72FrtU

[@JJ_Khailha]

I get it using GTE cars without ABS but how does driving a GT3 with ABS affect what’s taught in this video? Are stopping distances still reduced by moving it rewards if ABS is on and stops lock-up of the fronts anyway?

[@jessebilla]

Great video, TY!

[@akshayisr]

I thought hard braking means more front brake bias and trail brake means more bias towards rear. But it is opposite?

[@vsm1456]

I take it as, hard braking usually happens on a straight, from a high speed to a quite low speed. you'd want to have more braking efficiency but since it's a straight you can trade some stability for it. so you decrease brake bias and make rear brakes engage more than usual. you gain lap time in trail braking into a longer corner you don't brake as hard (= don't need as much braking efficiency), but stability is important. so you increase brake bias, let your rear wheels rotate more freely and thus get more stability at the cost of brakes not stopping you fast as they could. you gain consistency. and maybe lap time too if that increased stability lets you trail-brake more precise

[@dannyleeracing]

This is it - it's all about stability and consistency. If you move bias too far forwards in a deep straight line braking zone you are more likely to have a lock-up which loses you more time than any minor gain you could have had. Whereas if you have bias too far back into a corner you increase the risk of a spin and losing all that time and more in one fell swoop. Over race distance, everything you can do to rub out potential mistakes is what makes the difference.

[@seboy5483]

What if you can only change brake bias *before* a race? What should I do?

[@istachi]

Think about the track and car combination, tire wear and your skill and figure out the best choice. A FWD car might be better off having brake bias a bit to the rear to allow the front tires to wear less, as they don't have to brake as much, when they already need to accelerate, too.

[@cladpenguin6507]

Been looking for a vid like this

[@GeorgeGoVroom]

What do you reckon the time gain is on a hot lap? I set my Ferrari at Fuji to 54% all the time because I’m only just starting to learn it I found it to be more stable so I can constantly improve, but everyone I look at uses 52% but for me that’s so hard to control on Sector 3 I can do consistent times but I have a g920 so I rely heavily on getting my braking spot on as I cannot catch the slides as easily

[@howy5799]

You can shave a good half second off a lap with proper bias and pressure setup

[@rektchord]

super helpful! thank you

[@mavairick]

Just know that this has a small impact on your tires, especially if you put extreme values.

[@c4rd764]

Bit of a late question but would you recommend moving the brake bias further forward than usual for a particular corner when trying to out brake someone into said corner? Other than little question I have that your vid was very informative.

[@istachi]

Putting it in the rear would theoretically be the better option as it allows the car to slow down slightly quicker, but it might induce oversteer during trail braking. Risk versus reward.

[@gwenndolynnmecklenburg6457]

thanks for the info,...so the % is always calculated on the front wheels. If the BB setting shows 40% it's 40% on the front wheels and if it shows 60% it's 60% on the front wheels? Correct??, then this is the 1st time somebody explain this to me,....and I'm not blond btw. Gwenndolynn

[@dannyleeracing]

It's widely accepted amongst the sims that the % means front wheels, so yeah that's correct

[@ItsJustCarl1983]
