2009 Toyota Prius ABS

My car is hybrid sometimes when I start the car the break red light, break yelloo signal, abs and vsc on the dashboard remaining on and thats affects the breaking system ie the car running almost with no break if I pressed the badel, this conditins remainig for say some miles of after driving then these warning signals goes of and the break becomes ok.
but suddnly while driving the above warrning signale come back again and so on
a mechanics test my car on the computer and talled me it's the SKID control.
