Brake Fade
Just been out for a quick blast and noticed some very slight brake fade as I was returning home (after approx 20/25 miles) Can anyone suggest a good
set of pads for 'fast road' use that will take a bit more hard use .....the roads round here are hilly and bendy so lots of braking is
unavoidable. Oh forgot to mention its on standard Cortina calipers and I'll be fitting new discs at the same time

have you thought about EBC pads. I use ebc Reds on my Leon but its a heavy car. Ebc greens should be just the job for a locost and the kirkstone pass!

Brake Fade
Brake fluid does not cause brake fade. Fade is caused by the pads overheating. New brake fluid will improve the performance of the braking system but
will not effect the fade.
Regarding brake pads. I always fit Mintex M1144 to my cars and find them very good. I have not tried the other quality brands such as Ferodo but would
assume them to be as good.
When choosing pads I would go for a company that has success at the high levels of motorsport (Mintex, Ferodo etc)
The only time I have used EBC the pad came away from the steel backing..... I know of other people who have had the same issue. It was on my mountain
bike but it does not inspire me with confidence.

On some brake fluids they can actually absorb water. then under hard breaking this water can boil with the pressure and heat therefore suffering brake
fade as the liquid starts to boil and creating gas.

beat me to it thats why brake fluid must always be kept in an air tight container.

I'm pretty sure its down to pads as I could just smell them ever so slightly as i got home, discs have seen better days and I'm getting a
little bit of judder as well so gonna do the lot, calipers don't seem to be sticking or anything though, do you reckon I'd need anything
other than standard discs...just for road and the odd trackday....just bought the car and putting a few miles on it to try and find all these little
faults so I can sort it to my spec !!!

standard discs would be fine, is it a cortina or sierra front end?

What you say is correct but we have different understanding of the term "Brake fade".
Brake fade is where you have a hard pedal but no braking. That is the pads are too hot but the pedal is still hard. You press and press harder but you
do not stop.
All brake fluids (except silicone) absorb water which isnt a problem in its self as water is uncompressible but if it gets hot can boil which then is
compressable so your pedal will go to the floor. This can happen even though there is no pad fade.
They are seperate problems. In most cases its the pad that causes the problems. Fluid boiling normally only occurs in endurance racing with very hard
pads and poorly designed components and poor maintenance.

I use standard Ferodo road pads with no problems. If the pads are newish you may find they fade till they are fully bedded in, especially on used
disks. Track pads are not always better for the road as they need to be kept up to temperature and don't have the initial bite if they cool
down, causing brown trouser moments if you are on a long run. It's the organic resins and stuff in the pad turning to gas and aquaplaning over
the disk surface apparently. Read EBC's explanation.

I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

One word of caution regarding pad choice. On such a light car you need to avoid the harder compounds which are designed to reduce fade on a car
weighing several times more than a Seven. Stick to a soft compound and you will find that they stop better, especially if you dont have a servo. 
Cheers,
Raz

Before change anything
(1) Have you got a return spring fitted to the pedal ? If not it will cause the brakes to bind and over heat on as they warn up.
(2) Is the handbrake cable correctly adjusted ?
(3) Have the caliper seals been renewed ? the caliper seals act as returns springs for the caliper, they pull the pistons back a fraction of a mm,
when they age they are no longer elastic enough to dot this and the brakes bind.

I bought my pads from RallyDesign.
They are the homebrand performance version. I don't get any fade, even on a day around teeside they were fine. They do need a little bit of
warming up though!!
Summer's here!!!!

I wouldn't expect any brake fade on the road with the standard cortina set up, be hard pushed too get any on track, maybe worth checking things
are not binding a bit.
