Apologies for the pics on their side, they're not in my library but........
When sprinting I found the 'normal' cap leaks so I replace it with the race cap which has solved the problem

I had to turn the pictures around, I was paranoid about the fluid leaking out
....but somehow you've reversed them too!
I suppose if you're doing a job ......
That's it!!! Cheers!
I had the same problem with the brake warning light flickering under acceleration on my 420R. Topping the fluid right up to the 'maximum' line stopped it & I haven't had a problem since.
The brake fluid reservoir was leaking slightly when I first bought the car. I initially used Peter's kitchen roll & cable tie approach, but ruminating further on the problem, I realised that the plastic cap was bottoming out before the rubber sealing ring was sufficiently compressed.
I added a second rubber sealing ring underneath the cap & it's been leak-free for the last couple of years, even on track.
Ah, mine is definitely lower than that. Yours is almost full whereas mine is just above 'min'. I will fill up next week, ran out of time today.
It's just the fluid/float moving under acceleration, even when it's on max.
My 310R has done it from new, so I've just fitted the race cap. Problem solved. No more flickering and no more seeping out on track

#20 had it on both Sevens as GulfSeven says
