Emergency Braking Practice
Seriously though. Do it! I just got my bike insured again today so I thought I'd go out for a quick ride around the nearby country lanes. Having not practiced emergency braking much recently, I thought I'd get some in on the quiet roads. I did. I sucked! 5 minutes later one of THESE pulled out in front of me: I applied my poor emergency braking technique as best as I poorly could and stopped an inch away from that French bumper! Too close for comfort. I'm definitely going to get some steel braided brake lines installed soon and practice my braking more. |

AWWWW what a cute wolf. Look at those eyes, so pretty. Oh there's a message here.
I really need to work out a schedule so I go out once a week or so and just run through all the little drills to improve handling on the bike. Like emergency braking or sharp swerves.

It's funny how things like that work out. The last time I practiced emergency braking an hour later I needed it when traffic decided it'd be a good idea to go from 70MPH to 10MPH for no apparent reason on the freeway. |

Paraphrasing that, I would say that any evasive maneuver you ride away from is a well executed maneuver. Well done, Akima; riding alert always puts things on your favor, .......with or without steel brake lines. 1) Butt as aft as possible, knees clamping the tank hard, torso and arms relaxed, head up, eyes looking far away, balance sense in red alert. 2) Apply rear brake hard to initiate a quick weight transfer while gently squeezing the front lever, ..........feel the g-force yet?..........pull that front lever hard (but ready for a quick release and re-application if the front tire skids and you lose steering) while releasing pressure on rear lever (partially or fully (my personal preference)). 3) Slowdown as you keep your posture, vision and balance (the rear may want to fishtail some) and while you downshift (optional but much recommended), .....feel that front suspension hitting the tops? Practice at least 20 minutes each week !!!

Someone in here had the wind hit them while they were lane splitting on a corner. While at a lean it blew them partially under the truck on the outside of the turn. Thought it was you!

I already employ that entire technique! I've read up on the best way to do it. Where I've fallen short is actually practising it enough that it becomes muscle memory instead of just being a conscious theory (which wont serve me well in the moment). It's nice to see it concisely written like that though! The main thing I got right during my incident today (which I have trained into myself through practice) was that I progressively applied the front brake rather than just snapped it on. I'm sure I must have had an "oh sh*t!" expression plastered across my face You said in point 1 "eyes looking far away"... and you bolded it. That's something I haven't thought about doing. What's the reasoning? I'm guessing to avoid target fixation... so I don't hyper focus on the thing I am trying to avoid? |

Yea, to avoid fixating but I wouldn't only tell you to look far away. Can I challenge you to think of what you should be looking at or.... maybe what you should be doing with your eyes?

Presumably I should be looking for an escape route. I guess as well, I should not look at the object I am on path to hit, but if braking is the only option then I should be looking before the object. I don't want to stop in the object I want to stop before it.

oh yeah. i guess i have done that a few times.
as far as braking technique, i have never had any luck being in the center of the bike when braking. every time, without fail, it winds up in me pushing down on the bars to keep from going forward which when braking hard means you are pushing out your front tire and putting in all kinds of crap input that you don't want into the bars which start slides or turn small slides into crashes. these days what i do, is basically never ride centered on the bike, i always ride on one side of the bike or the other. its good for turning sure, but its better for braking. instead of having to use my upper body for support, the "in"-side of my torso rests on the tank while my outside leg braces the peg so that the inside of my thigh is pressed against the very back of the gas tank, which when combined with the outside leg pushing back keeps you from sliding forward and gives you lots of freedom with the controls up top. using the other peg push forward helps a lot too. i think someone told me this is called pivot steering. not sure why anyone would call it that. but anyway about the actual braking part... theres 3 zones of braking in my mind. the "up" zone, which is about the same as rear brake... not much braking can be done, go too fast here and it just locks... really not much going on here. the "mid" zone, which happens after the front of the bike compresses. this second zone gets you most of your braking but you can still go for more this is where most people stop... doing things too quickly in this zone can send the rear tire in the air pretty easily. and then the "down" zone, which is really sketchy to get to and really wont happen without good, hot tires on clean dry asphalt. trying to brake this hard with **** suspension or **** tires or poor conditions results in a nice front end slide that sends you into the dirt... but anyway.... if you jump steps you slide. so take it one zone at a time... bite it to get it into zone 1, ease on smoothly to get a nice mid-stroke, then once its made it down far enough you can SLOWLY step into full brakes. depending on pads, this might not really be very much (stock non-sintered pads) but with good pads this will be pretty extreme braking... think close to 2 Gs. granted, when you have lots of practice, getting that far only takes about 1 or two seconds. smooth is the key. you go smooth, you can brake like you have a parachute. do it wrong, and it feels sketchy as **** and you wind up sliding all around

@alex.s: that all sounded very zen. Lots for me to think about. Thanks. I'm guessing in zone 2, you release the rear brake as you apply the really heavy front braking?

just in case you were wondering, 2Gs lateral with no aero means you are flying off the side of the road
also, i use no rear brake if i will be going past the first zone.

There is a natural tendency to look close in front of the wheel during parking lot practices. However, that is not good for creating the habit of looking for a escape path and much less for keeping the balance when the bike becomes unstable under really hard braking. Keeping your eyes on the horizon and level gives your internal ears a solid point of reference for pitch, for yaw and for lateral roll of the machine under you. I have collected for you and other practitioners some very useful articles and some previous threads about emergency braking: Braking Tips Some old but good studies on braking Brake progressively Keep your controls covered while riding on the street Stopping distance calculator During an emergency situation, will you steer in the right direction? Bike Crash Evasion and Mitigation Keeping a log book where the stopping distances are recorded will show the real progress. Once the contact patch is consistently pushed to the limit (some chattering may happens), the practice for quick release following a lock-up and brief skid of the front tire can follow. And that is just basic braking on a straight line and dry pavement. After some degree of proficiency is achieved, more real world braking alternatives should be practiced: while turning, on wet surface, on sand, quick acceleration before coming to a full stop, braking followed by swerving, etc. The skill is not needed for track-days and racing, but for street riding, ........nobody should be doing that before at least mastering emergency braking. You saved the day simply because you had put some effort on improving your braking skill above MSF's basic training..........that is what my experience tells me.

@Whiskey: you recommend those do you?
@Motofool: thanks! Will read/re-read all of that. @odn3: if you ride on the street anywhere with a population consisting of more than just yourself then you will experience someone pulling out in front of you. Your emergency braking practice is essential to your survival. Also: remember stopping distances. No point knowing how to brake perfectly if you're riding so fast that it's physically impossible to stop in time. In a sense - the better you are at braking, the faster you can safely ride! |

Hi Akima,
I have been thinking about installing some braided lines also. Shout if you want to get together for an "install party", I believe I have most of the necessary tools from doing this on my car. Glad to hear you avoided the Citroën :-) Cheers, Pete |

Yeah I fitted the front line about 3 1/2 years ago, very noticeable difference in the feel at the lever, much more precise/less sqiudgy. HEL have a pretty good reputation, the lads on TT superbikes trust them to make the brakes work, & I can't think of a much more demanding application (just don't do what I did, ordered them on monday, threw the bike down the road tuesday, & they arrived thursday... ideal timing) |
