265 So I assume I need braided hoses?

Christ, is this still going on

 

it will until he convinces himself he has won Steve, very special.

 

Please lets all agree that Aerofoil is right,and everyone else is wrong,and get back to serious matters............Have you seen the price of fish lately?.

 

Yep but when you factor in the speed of the service it's not bad there's a lot of drag when the fish has come out of the drier due to the hot batter
That's why a large fish chips and mushy peas is £6

 

Surely that depends on the type of batter? I know nothing about it but I'm sure I'm right

 

I am sorry Phil, I have to disagree with you. It all depends on the temperature of the oil. The colder the oil, the greater the drag, and its only £5.99. Please get your facts right.

 

ADMIN. Please close this thread,as i think i am losing the plot.

 

I'm getting ripped off then
And to think fishtec is a reputable chip shop who wouldn't take a fish to far

 

And while your at it Ban the Troll please, can do without people like this, just gets people's backs up and spoils it.

 

Why don't you both listen, I'll spell it out so you understand, the oil temp x y = z and Lewis Hamilton means I'm still right or I'm not playing anymore

 

The problem with track novices braking for too long and overheating the brakes is that they tend to hang on the pedal all the way into corners whilst scrubbing off very little speed and perhaps come onto the brakes very slowly at the start of the braking zone, thus they aren't really spreading out the energy over more time just keeping the pad sat there on the disk getting hot. A mate of mine did that for about one and half seasons when he started racing, we could see it in his datalogs and the effect on his pads which were tending to glaze over all the time. He was also bleeding his brakes every race whereas I personally only done mine every 3 or 4 events (if the pedal is good why bother, more chance of damaging bleed nipples).

I also studied Physics to degree and then PhD level, also been around race paddocks and garages a fair amount over the past 7 years, both of the main protagonists in this thread have made points which IMHE are correct.

 

enough, were bored of it now, let's talk about fish and chips , don't encourage the idiot.

 

What a great attitude.

 

Appreciate the on-topic input and support.


Dragging brakes round a circuit is definitely bad technique.


Regarding the heavy and late braking, which is the best technique for lap time, I have been generous with jjjones82 as we have set the entry speed for both situations the same. That is a false premise. In reality the late braker has a higher velocity at the braking point because he will be accelerating all the way to it.


That higher velocity for late braker due to the velocity squared element of the KE equation means there has a huge amount more KE to shed. That difference is hugely significant, even for small velocity variations, and why I have left it out of the discussion until now. Physics and the reality of the situation.


So in summary, late and heavy braking is the best circuit technique but correctly conducted it’s the worst situation for brake temp and shouldn’t be considered a preferred technique for limiting brakes temperatures.

 

its looking like we need couple of vehicles sent to Bedford's long straight kitted out with thermo stickers on their callipers, while we all stand around betting on the outcome (losers buy for lunch for everyone)

 

not sure i could be arsed with that, i'm happy with my technique and temps, the rest is willy waving and trying to impose his own opinions on others. I think i know who it is anyway, been banned from countless other forums for the same attitude to others.

 

Well that would be interesting but not the best result. You would need to do for about 10 laps and where the late and hard braking vehicle was driven to benefit from that technique. Thats where all the additional heat comes from, more speed pre braking point, faster lap time.

Just a side by side comparison would prove nothing relevant to the OP's original problem. It would need to be trackday or race orientated comparison.

 

You are boring though, lol, the amount your typing you need a job

 

you should be impressed like the rest of us Steve :rolleyes:

 

Shhh don't feed the troll!
I've given up, he changes the parameters of his argument every two seconds!

 

haha, I'll not post again, hopefully he will bugger off to another forum.

 

You mean parameters relevant to the real issue rather than examples like leaving the handbrake on in the pits.

It was good to bounce some theory around with you though.

 

Having discussed braking techniques,the rising price of fish,what i really want to know,is why you are not going to Spa this year Steve.

 

I'm skint

 

Spent all his money whilst out in the Caribbean

 

I feel a bit unwell after reading this thread. Thanks Aerofoil.

Serious question now - Aerofoil, are you on - holiday/days off/unemployed ?

 

Anybody know the price of cheese?

 

Glad to help.

2 out of those 3.

 

I bet the OP wished he never asked..what a useless thread,filled with everything that's bad in internet forums.

 

True

True Andrew but how did you end up finding it ? I never saw it.
IME, the very first advice a track instructor or a seasoned TD Billy will give you to better manage heat is to minimise the time the pads is in contact with the disks. Even if that means braking harder. Maybe they're all wrong.
Ah, also, all brake lines are braided, even if not metal. They are usually made of one of or the other of Dupont's specialist material with a funny name. They have similar stiffness to steel ones but are rubber coated. If they were made of rubber, they would be like big balloons or rubber johnies.

 

Weirdly, I have posted on another forum about what can be done about Megane brakes

I have 660 fluid, braided lines, 2 piece discs, XP10 pads, bigger discs... yet get the spongy pedal feel

I think it's just how modern brakes with servos are, hence why pedal boxes are "a thing"

 

I think you must have air in the system, i tried to do mine myself and just couldn't get a decent pedal, i took it to a local garage and they plugged it into a laptop and used a pressure bleeder and now my pedal is solid, apparently i had air in the ABS module and with the laptop it opens the ABS valves so you can get the air out.

Believe me i have done loads of brake fluid changes on cars and never before had a problem before.

 

But if air was in the system, it shouldn't start off ok, get worse on the track and when it cools, get better....

Should it?

The only ones that have bled the brakes were garages but I doubt any used a laptop. Is it a case of asking them how they do it to make sure they do?

I'll happily rule it out

 

There is a system that garage's use, can't remember what it's called, i have seen this option in Renault clip i have, but haven't tried it yet.
