Lights out on dashboard!?

[Ralliart1]

I drove the car a bit hard to warm it up well for emission test,when it cames out on dashboard the red handbrake light continously and the amber car (near TCL)flashing.Pull over,stop the engine for a couple of seconds,restart was the same.Stop again,leave it a few minutes,all ok,till I drove home never came out again.
What'S this,had anybody same experience?
Cheers,

Handbrake light comes on under hard acceleration when your brake fluid is low.

Could start with that?

Brake fluid level checked,is on Max.

how far down is the strainer in the brake fuild , had one once that was push right down and made the light come on under load up

[Ralliart1]

Thanks again John,the strainer was deep and oblique inside.

What about pad and disc wear?

[Ralliart1]

The discs are like new,the pads not to bad as well.Looks like the stainer causing this poblem.The amber car icon why flashing don't know,maybe for same reason.
