Hey, Denty; how'd you get on with the YELLOWSTUFF?
How do they compare with the REDSTUFF: bite, dust, cold braking, pad warm-up, fade, etc?
In anticipation...
Hi,
Well sorry for the massively late reply...!
So after around 5/6 laps around Brands Hatch Indi with the yellowstuff fitted I started getting BAD brake judder... I carried on and after another 3/4 laps the juddering just stopped as quickly as it started!!
I do try to have warm down laps and come in to the pits etc but I get soooo in the zone on track usually I just carry on...
After about another 45/50 mins on track I noticed the brake pedal started started to drop, prob boiling the brake fluid.... another lap or two later and the brakes were basically usless so I pulled in to the pits
Getting out of the car and looking at the brakes I was shocked to see the yellow stuff pads smoking, all the yellow paint had bubbled off and I could hear a hissing sound which I presumed was the brake fluid boiling...
I thought my day was over but within the next 15 mins the firmness came back to the pedal so I went back out on track again - all good! pedal wasn't quite as hard as before but still worked ok.
So I completed my track session a couple of hours later (a naff looking fiesta ST was trying to keep up with me at one point but he ended up going in to the barriers.... saw it all in the rear view mirror....nasty!)
On the drive home I had a grinding rubbing sound coming from the brakes but they still worked fine.
The next morning I went to the garage and pulled the pads to put the red stuff back in - the yellow stuff pads were 75% worn and were falling apart at the edges and looked blistered...
I rang up EBC and they said this is normal under hard track use so fair enough.
I put the red stuff back in and all has been well up until about 3 weeks ago and I now have the brake judder back when the brakes are warm.. I've tried the usual 5/6 hard stops from 80 but this still hasn't sorted it so I guess I may need to get my discs skimmed or replaced.
All in all though I was happy with the yellow stuff and would recommend to anyone with an RS3 / TTRS.
I've since upgraded my brake fluid with castrol SRF and all seems good.
I might wait and see what the discs are like on the new RS3/TTRS - hopefully should be a bit better and less prone to pad build up. If there the ones with the frilly edges they look pretty cool too!
