Hi Jonathan,
Knockhill is notoriously hard on brakes as there are two heavy braking areas from near max revs in 4th gear in succession on what is a relatively short lap.
Ten to twelve laps will be enough for your peddle to start giving you that sinking feeling - white knuckles at the hairpin - then it's time to come in. Make sure you do a cooling off lap where you should avoid touching the brakes as much as possible.
Has the vibration gone now your back to normal road use?
What type of brake fluid are you running?
Was your brake pad wear warning light coming on on track?
Have you considered Gucci nubuck race shoes a la Mr Campbell Griffiths et al?
Cheers Mike

Thanks guys for your replies.
Don't know what brake fluid is in it, but I've got the Castrol Super Dot 4 to replace it with. Brake warning light didn't come on (not that I look at the dials when I am on track. People ask me how fast I go on track and I say that I don't know - I never look at the speedo, just the tachometer now and again!)
Brakes returned to being fine very quickly once stopped. I did do cooling down laps and handbrake off in pits.
I'll have a good nosey during the week to see how much pad I have left.
They are not Gucci, but they are nubuck leather [

Jonathan,
had exactly the same thing happen at the last Brands Hatch track day.
never happened before but I was running new pads EBC yellow stuff and resurfaced brake disks (second set of pads) - skimmed on recommendation of my OPC at the service. I had run the pads and disks in by driving from Glos to Brands! Obviously not enough.
They were fine for the first two sessions then got really bad when hot and I almost left the day becasue of the vibration but got better as the day wore on and now no vibration at all (but haven't doen another track day) since.
I guess it was just the pads and disks bedding. If warped then they would show up at low speeds as already pointed out. The vibration only happened when really hot?

my brakes also juddered after 3 laps each session at S/stone in Nov. could have been pad material breaking off and sticking on the discs, mine still judder slightly on the road. JZ reckon that stock discs and pads are fine for t/days, but that I must have used them too much and too heavily!
I had a problem a couple of years back with a 944 cab 'cooking' the front brakes. The piston's were sticking in the REAR calipers, so overworking the fronts.

There is of course the ultimate solution and that is to upgrade!
I went for the BIG REDS - Turbo 4 calipers and discs all round three years ago and braking problems have never been an issue since despite regular track days.
I have always gone for standard pads as I reckon they are cheaper to replace than the discs as they cause less disc wear than the more abrasive type.
I also went for braided hoses.
Downsides? Front shocks take a pounding and I have now upgraded to the full T4 suspension - springs dampers and anti-rollbars.
Maybe Santa will bring some power upgrades.
Complements of the season to all.
Cheers Mike
