brake dics advse needed

[Ess_Three]

Well I would love to find a road I could do 80 on! Except motorway of course, even then 80 at peak times can be an achievement!
Most roads I travel on you are lucky to do 50.

Just because YOU can't, doesn't make it impossible....does it?

Still sceptical about the gas.
Gas can only be formed when a material changes state, solid to liquid to gas is the general thing.
So you are saying a solid material goes straight from solid to gas?

So the rest of the braking world are all wrong, and you are right?
Is that it? 

I have never seen a brake disc red hot so just dont believe this!

I've had mine cherry red...
But you don't need them red hot. In fact, if they were red hot they'd deform as they'd be malleable.

Anyway, all you need is the discs to be hotter than the temperature rating of the pads, and you fade.

If you don't believe me, go find a quiet road - a difficult job in your case it seems - and do some heavy braking then measure the disc temperature with an IR gun.
100s of degrees C is easily seen...the wheel gets hot enough to boil water on contact.
Why do you thing repeated heavy braking also kills track rod ends and ball joints?
(Heat)

Cheap pads glaze over at low temperatures...then you press even harder trying to brake, and get the gas layer...it's a lose lose situation.
Fit decent pads and decent discs and the problem goes away for most road driving.

Iv had my old 280's Glowing hot too. and smoke pouring off as tho they were about to set fire

this was main reason i moved to a 312 set up

Do you watch le-mans or rally? I have defo seen their discz glowing orange!  The more & harder you use your brakes the hotter they get due to friction & gas build up on the surface or discs & pads

I had grooved discs on my old 8v with green stuff pads and was noticeably better than the standard setup ive got on the 16v. But i thought  GREEN stuff pads were best for fast road use as the YELLOW and RED stuff pads didn't start working properly until they are at much higher temperatures and were therefore more for track use???

In fact, just been on the EBC website and they recommend green for cars under 200bhp for fast road use, red for performance cars over 200bhp and yellow for hot hatches to american muscle cars and occasional track day use?

Wouldn't green stuff pads been the best option? or otherwise your brakes won't work very well unless you are thrashing it everywhere???

No you didn't.
You were mistaken.
Len say so

I used Greenstuff pads when the car was more standard, and found them pretty good.
They work from cold, aren't noisy and don't give off much dust.

As the power rises, suspension gets improved and brakes get used harder, I found them lacking...but then a Ferodo DS2500/Miltex M1155 upgrade is an obvious step.

I had EBC Greenstuff on my last mk2 16V and really wasn't overly impressed tbh.

[Khare]

I've got Mintex M1144 on the front and find them good, but have made them fade once or twice on the roads.

My point is you are defying the Laws of Physics.

I repeat solid-liquid-gas

To change state you have to apply heat or pressure, which indeed we have in this case.
But what is being said is that a reaction takes place that the pad material goes from solid to gas all in just one reaction.
That is what I do not believe is possible.

If there is gas then it would be far simpler and way cheaper to put groves in the pads. Why is this not done?
Cross-drilling is done to aid cooling of the disc.
Grooves are to assist the dispersal of dust/debris.

Oh and I see a lot of childish, derisory comments but no facts!

I asked what these gases are!

I also guess again, as no facts are forthcoming, that these said gases are coming from the pad material?
Can somebody say what is in the pad material that gives of gases?

As I assume it doesnt come from the disc as that would require vast heat and pressure to vaporise!

It used to be a lot of asbestos that was great at doing its job but a bit carcenagenic unfortunately!
