Bedded in nicely with new discs and decided to put them through their paces on very demanding twisties ... (very)
Bends, hills, brake, accelerate,do it again etc and on the 15th ish bend ...
Bad brake fade and on stopping, all 4 smoking ....

Whilst they work they are increadably good, but i m a bit dissapointed they faded so rapidly, yet glad i now know there limitations..

I assume this is normal (?)and would dread using the car on a track if it were ...

No that is not normal. Are you sure it is not the fluid which has boiled?

I've not used Yellowstuff pads (I use Pagid Yellows), but it does sound a bit soon to be experiencing brake fade? (I suppose it depends on how hard you were driving though laugh and to get all 4 smoking sounds like you weren't hanging around laugh )

On one of my first track days, I'd to get 10-15mins or so out of standard pads and discs before having fade.

Have you changed/ upgraded your fluid recently?

Fluid is my next job on the list, but in view of the smoke and very demanding road i assume its more likely to be the heat in the pads ...

i believe it's dot 5.1 brake fluid that resists boiling as easily as standard

Unless you were really riding the pads, i think it is a safe bet that it is the fluid.

I have never experienced any fade with these pads, 2 or 3 hard track days later

Brake fluid absorbs water. The lower the rating, the less water it absorbs, and longer it lasts, but it has less resistance to heat.
The higher the Dot rating has a good resistance to heat, but absorbs more water, so will need changing more often.

For example*

Dot 3, will last 4 years between changes, but will boil at 100 degrees

Dot 5, will last 1.5 years between changes, but will boil at 300 degrees.

*they are made up figures!

I use a Dot 4 racing fluid - Motul RBF 660, good life and good resistance to heat.

But pretty much any Dot 5.1 fluid will do you.

DON'T get DOT 5, it is not suitable for coops (DOT 5.1 is)

Quite a few on here (particularly the more track focussed) seem to use a DOT 4. I've just changed to the same fluid as Matt (RBF660), and in seven 20min or so sessions around Silverstone GP (which includes a 130+mph to 40/50mph stop on the hangar straight), I didn't get any fade.

And I wasn't exactly hanging around either!

sounds like the road i drive is a bit similar but with bends every 75/150 meters and up and down all over maybe it s tougher than the track on the brakes ?( but you can see for miles :D)

Anywhere near me? (I'm in Stone, and I notice that you are in Staffs).

It sounds like a road that I might like to take a drive along laugh

I concur, a crazy sat nav took me round the back roads between leek and hathersage once and the hills and bends just don't stop.

Sadly was in a kia sportage at the time, so didn't enjoy it as much as I should smile

bosco, if this was your first hard drive since u installed the new yellowstuff pads, early fade and smoke/burning smell is normal. the pads are out-gassing.

assuming u didn't glaze them, let them cool down and they should perform well your subsequent runs.

Had a re run....

it s definatly the pads overheating and fading which becomes evident when you start the steep descent and initially smell them !.... stop and the smoke confirms it..

nice road though..

Just had the yellow stuff put on all round and rear disks changed to grooved and drilled, front already were. Undecided on the improvement at the moment. God did they squeal for the first 100 miles, my god it was awfull.

Have settled down a bit so ill report back how they perform. Had the fluid changed as well.

I am running, yellow stuff pads and 3G discs up front with new brake lines but standard flexi hoses and new dot 5.1 fluid, rear brakes are mintex discs and pads.

No issues with fading at all, and our roads are much like yours,
hence why I wanted good brakes.

Have you fully bedded the pads in Ebc yellows have a top layer designed for bedding in.

Don't under-estimate the importance of a good brake fluid.

Brake fluid, by nature, absorbs water over time. The higher the DOT rating, the quicker it absorbs water, so keep on top of the changes!

I have had fade a few times, where there has been smoke pouring off the caliper, but that was because the fluid was boiling, not the pads.

just to update,

fluid and hell stuff brake lines done and that road is so demanding the yellowstuff pads do overheat smoke and fade to nothing...

To be honest i think a track would be less demanding,but could it be the grooved and slotted discs not disipating the heat very well ???

Wow, it must be a really demanding road, unfortunately i'm not familiar with it.

I'm surprised because i've never managed to cook mine.

Did you use racing brake fluid?
