Anyone got these?
I had these fitted several months ago together with EBC grooved discs
Today I took my 3 Belgian suppliers out for a blast on a country road.
I did 3 runs round this wee country road
Out of the factory - quick blast up to junction and brake.
Then longer blast round back road with hard braking to stop from about 110mph then back down again and hard on brakes at similar speed.
Pick up passenger 2 and do same thing, then passenger 3
On third run the brake fade was pretty bad and quite a lot of smoke from both front discs/pads
OK - this never happens(as in being used like that), but at the price of the pads I didn't expect so much fade and now they just don't have the same bite anymore?
Whats that all about?
Cheers,
Shaun

I've got them in my classic with grooved discs up front and they are the dogs danglies for the sort of driving you have described.
It sounds like you have glazed the pads, did you bed the pads in properly as in through several gradually harder stopping runs with adequate cool down between.

Gentle braking for a couple of hundred miles then some harder braking.
OK i appreciate what I did today what abnormal, but I didn't expect the fading

With used discs it's very easy, six hard stops from 60-30 then let them cool without stopping, then same again 80-30, then 100-30 all done on your private test track of course. All this has to be done without activating the abs, i did this by removing the abs fuse, the brakes were so much better without the fuse but thats another topic.
do a search on here and you will find similar instructions.
You will need to deglaze the pads and then run through the proceedure.

I thought that grooved discs prevented this?
What make are your group N discs?

Assuming you bedded the pads in properly, they're unlikely to be the cause.
How old is your brake fluid?
if you're using a hygroscopic type fluid (dot4), then perhaps it needs to be changed. It will absorb moisture and can start to boil. This will create bubbles. It feels very similar to brake fade.

I had the DS2500's and could never get on with them.
Changed to the Performace Frictions and find them leagues ahead.

I think thats maybe whats up with it.
Pressing pedal before had an instant bite whereas now you need to press it a bit harder to get that bite.
