saying there is no application for the rear brake on a track isnt exactly true. Did anyone watch Stoner sliding the rear in at donington. He was making good use of the rear break and worked for him
Even if you use 90% front break and just give the back 10% squeeze. Your gonna be stopping 10% quicker and on track thats going to show over a lap time.

On the track using the rear brake generally causes alot of chatter besides so much weight is on the front the rear wont add much braking power. Just look at the brake setup on a modern sports bike, you have massive twin discs with 4-6 pots per calliper compared to a tiny disc with a single piston

was stoner using the rear brake or was it electrics and riding style enabling him to slide it in.
craig jones slides it in and in good style and hes said its nothing to do with the back brake,more a case of dropping it down through the gears and letting the slipper clucth do its thing

thats definately wrong. If the back brake contributes anything at all to reducing the distance you stop in on a track you could have braked heavier on the front and reduced your stopping distance even further. If you want to brake really really late then 100% of your braking will be being done by the front. You are definately braking way to light and losing time if the back brake is contributing anything at all to reducing stopping distance
you can argue that the back brake hs applications on a track (which I still cant really see or maybe they are beyond my ability to use effectively) but helping you late brake definately is not one of them. Like I said earlier Carl Fogarty never used a back brake thats a good enough arguement for me.

Yeh they are sliding it in flattrack style and braking traction with power they certainly wont be using the rear brake to break traction thats (relatively for people of that standard) novice stuff.
when I spent a day learning to ride flat track bikes at first you had to get it going into a slide using the rear brake (quite easy) - but that was the beginners step the end aim was to start the slide by braking traction by leaning the bike under engine braking then the application of power - Which was very very difficult! anyway my point being I doubt racers are using the beginners method.

did any of your flat tracking experiences help at llandow or pembrey, just curios as to what you managed to carry over from dirt to a k7 on track ?

Moto GP bikes have a rear break, thats enough for me. They have one pursuit, to make the fastest bike. If a rear break dosn't do anything why have something of a significant weight on a motogp bike?

I didnt say they dont have uses just that they arent any use for reducing stopping/slowing distance
and I am not sure of this and could be compeletely wrong but regardless of whether they use them or not ,dont they have to have them due to regulations anyway? Prototype bikes they may be but they still have to conform to regs to some degree.

I thought they only used the back brake when the front was in the air (wheelies )

I think It helps in bike riding in general that a big rear wheel slide isnt going to scare the crap out of you, I would also imagine it makes you way less likely to highside yourself as when you do get a slide your not likely to just completely bottle it and slam the throttle shut. I have had some pretty big on track unintentional mid corner slides (had a great one in the last session at pembrey!

), and I have never come close to high siding myself - I could put that down to an MX background and flat track experiance ( although it could just as likely be dumb luck

).
Its definately worth a go deej, and its fun,difficult and rewarding if nothing else. I am sure it can only make you better at controling slides and getting used to bikes moving around under you

thats exactly what james buckingham told me his rear brake was for and that reason only

if he doesnt need one for normal duties on track then why the hell should i

i'd best get the back sliding before trying that then. never had a slide on the zx10 but did have a stunning one on the ron haslam school fireblades but it was running bt014s and not slicks

Just got a new set of pads on the front. EBC HH pads. Wow! Brakes are suddenly good, and have bite!
