Yes. And why did I locked them? I will quote myself.
"But in a situation i described above you are just not prepared and you arent "awake" enough to react properly."
When you are out on track, doing lap after lap, you are all in the "mood" for perfomance driving, not locking the wheels, not putting too much power onto the wheels, and so on. In everyday traffic you go easy with the brake pedal, you brake from far distance. What I want to say is that you don't think like you were out on a track. If a dangerous situation occurs and only solution is to stop as soon as possible, believe me you would just climb on the brake pedal.
IMO wheels lock easily, It isnt too hard to lock a wheel even on speed. Dont know for high quality rubber, I'm on budget tires - probably the biggest reason why it is easy to lockup. Also widht is only 175.
maybe i am superman, but many times i needed to do emergency braking and i did brake without locking. on old tyres. without abs. with 3 passengers and a load.
oh and if you did indeed brake from 140 to 0, the tyres, after the braking, are seriously damaged and are for scraps.
i think he is either telling lies or very exaggerating.
You might not be awake enough initially, but less than one second after hitting the brakes and seeing the hazard, the adrenaline will have kicked in and you'll be fully alert. As a locked brake stop from 85mph is going to be about 8 - 10 seconds that's 7 - 9 seconds of time to cadence brake.
Knowing how to cadence or threshold brake in perfect conditions is essentially a useless skill. And therefore one can presume that you can't do it at all if you can only do it consiously.
Errrr, yes of course they are important. Exactly when did I even suggest that spatial awareness, anticipation, or 'safe driving lessons' weren't required? I said that advancing driving skills are utterly pointless if you can't use them when they are required.
Oh. I thought you were commenting on my post, as you quoted me (and not all of what I said either, suggesting you'd trimmed the quote to get the bit you wanted to reply to).
That was my fault, I should have got the context of the conversation and realized what we were talking about.
Back on topic:
I haven't reduced the the brake boost, I just like how the brakes feel when the vacuum has been depleted.
From what I have read, you'll probably want to replace the whole vacuum assembly with a hydroboost system for safety reasons (loosing vacuum when you really need it), however you can get a bigger master cylinder. Using a bigger master cylinder should require more force through the pedal but it will also make the pedal travel shorter.
It is something I have also been wanting to do since I have owned the car, but haven't gotten around to doing.
Yeah, more feedback. . I sometimes get bored at 3am(When I don't feel like reading forums, coding, drawing, playing video games, or watching porn) I go out and drive on our local back road.
I sometimes catch myself riding the brakes a little with my left foot so that I get better feel of the brakes approaching a turn.
Lol same but you have to be careful, I once got to the point where I was having too much fun, overused the brakes, and couldn't get any brake boost, like you I was on some canyon roads. Losing brake boost there is really scary and is not something pleasant to experience.
I understand that situation. You are going to do a "panic" stop. However, I would suspect that there are many things different on the car than what it was probably designed for in the first place... like those hard, skinny tires and the road surface was probably a factor as well.
Romping on the brake instantly will sometimes cause lockups because weight transfer is abrupt and probably some other factors. However, if you properly roll into the brakes with a car with proper tires and proper brake pads and disks, on a decent surface, it is going to be very hard to lock the tires up. As you slow down, which happens quite rapidly, it will get more and more likely you will lock up if you don't reduce brake pressure... modulate as it were.
All I know is that with decent tires on the two cars that I have used on the track, with proper initial braking action, I can't lock up the tires until I get to a slower speed. I am using performance brake pads that do heat up quickly so you get full braking action quickly. (unlike track pads that have to have heat in them before they really work well)
Getting to that slower speed does not take that long. It goes by pretty quickly to you because you are so engaged with what you are doing. It might take a lot longer in reality than you think, but still, you could have hit the brakes at 85mph but not started really locking the tires until you were at 50mph. It goes by quickly in a situation like that.
Actually, I was just covering my brake pedal to prepare to left foot brake for a tight corner, but vacuum assist takes a lot of feedback from the brakes, so I end up depressing the brake pedal without knowing.
Actually, it is kind of easy to lock up the brakes. I remember this incident back a few years when I was getting my license. I was driving with my mom on our local canyon road outside out house. I have no ABS on my Lexus ES300, and a garbage truck pulled out in front of me from a neighborhood, and I had to brake quickly, I just tapped to brakes quickly, and I heard skidding sounds, but I did stop relatively immediately and was able to get out of the way of the truck.
Yeah I did the same thing when I was practicing left foot braking, that's why I like to have less power assist because you can tell if the pads have made contact with the rotor. Where as if you don't realize you are slightly riding the brakes it may seem as though you have a loss in power.
I have to kind of hover my feet actually, when I brake gradually, until the vaccume goes away. Actually, nevermind, it would be nice if it was gone. I think power brakes are enough.
Just reading some of the older posts in this thread. If Lovretta's flag is correct there's no way in hell I'm ever going to go near a public road in Croatia...
Hard to understand, but I did skid for that long. Now when I read those lines, and think of that what happened before, it's bit scary to think of it... But as Ive mentioned, that 85 mph skid was few years ago. Back then I was young inexperienced and stupid driver, who thought he knows how to drive.
I've mentioned that ONLY because someone said that it is impossible to lock wheels on high speeds. I've said that because that REALLY happened to me, skid mark stayed there for long time, tires were changed few days after that.
No I was not joking. And I'm not proud of this braking. But it did happen. And I've written it here ONLY to show that it is possible to lock wheels. Sh*t happens.
And I don't like the thing that this thread in some parts went off topic - onto discussion what I did and what I could have done (not quite sure is this grammatically ok).
You cannot judge someone and eventually whole country from a few forum posts, I written here two things that happened to me in my life which both lasted maybe 15seconds, but scary 15 seconds of it. Again, it was written here only because someone said it isn't possible to lock a wheels when braking - and I know it is possible.
Everyone sorry for the offtopic and multiple repeating of "only for the...".
it frustrates me to no end when i read such NONSENSE.
'shit' did not happen. you made that shit. if you want to take praise for the good things you've done, you have to accept the opposite when you do something... well... shitty. If you do not, then praise loses significance. black/white, ying/yang, good/bad, duality and all that jibba jabba.
i've heard this so many times it has become a major nuisance.
- "i smashed into a wall because i took the turn too fast. well, shit happens."
no. that is not 'shit' happening. that is you doing an error. 'shit happening' is the wheel coming off even though you had your car serviced. 'shit happening' is not when you had control of the situation, but managed to cock it up because you were ignorant or just plain stupid.
if you feel like it, you are free to replace 'you' with 'someone' or 'anyone'
well, yeah. you can and in fact it is quite easy most of the time. not for the whole country, of course, but for a single person it is quite easy.
here let me give you an example... first, just tell me what do you study and/or work, so that i know what kind of example to give you.
In addition I've always thought bigger brakes were less prone to brake fade, too (coz it would take longer for them to heat up?). Up to a point I suppose depending on how much torture they get to endure.
Just me assuming though, so it might be wrong or irrelevant
that's the point of 'better brakes' in general, isn't it? i have noticed that if i go about braking with my lancia, really hard, after a while it doesn't feel to be up to the job.
