You get a 2nd chance...
Even when a pad disintegrates, you get a 2nd chance.
When brake fluid overheats, it boils, and your brakes catastrophically fail.
No 2nd chances...
I repeat what I've said before - don't venture onto a racetrack with stock fluid - the brakes WILL FAIL after 5-6 laps when the fluid boils.
A good fluid which is affordable is Motul 660, available in most motorbike shops at about 40% of the price of Endless RF650.
Trust me when I say this - I've done 16 track days in my 86 and I learnt the hard way.
I also thought I'd just put my toe in the water and see what happens.
Fortunately my brakes failed and I went off where there was nothing to hit.

Thanks Fish.
He doesn't do track-days else I would do fluid and pads straight away like you said.
In my personal experience, I would never chance it by doing more then 4 hot laps with any street car with stock brakes if I could help it - did it once without noticing and brakes go spongy quickly after lap 4.
My usual procedure for my BRZ and previously Impreza 2.5RS (both stock brakes and fluid) was to do 2 warmup laps at medium pace, 3 hotlaps, 2 cool down laps (not touching brakes), 3 hot again, followed by 2 cooldown and then pits.
Doing anymore then 3-4 (at most) is asking for trouble, this is obviously very track and driving style dependent too. Contrary to belief, braking later and harder heats the brakes up less then easing onto them for extended periods of time.
I know guys who can bang out amazing laptops on stock brakes without any issues and other who manage to cook big brake kits with average lap times.
In summary, I agree: if you are going to be hitting the track often, pads and fluids FTW and its not expensive. |
