Grinding noise for 20-30s at cold startup...

My 2001 prius is experiencing the same grinding noise that you posted. i sent the car to toyota dealer after i had the abs and the brake lights on all the time even after reseting thet faults and the dealer said we need to retplace the abs pump and the cost to very expensive in sweden it cost 25000 kronors almost 2.5k dollars.
the thing is i heard so prius factory problem about this fault. any idea what can i do to lower the price of fixing my abs pump...

 

Buy a used brake actuator assembly and install it yourself.
