This is has been on my do list for while, I did not know what do expect here is my mini-summary. I used an ebay mini VCI and a 2021 version of techstream ( one with a loader that by-passes the requirement for a license) Prius AirBleed over view, total time 1h30 Start of techstream / select the ABS/VSC/TRAC , the under utility AirBleed.. the entire process has multiple reminder for re-adding fluid to the Max line The High Pressure tube ... step is all automated. The braking system makes a bunch of noices. An other automated step. Finally the person in the driver's seat start interacting with the brake pedal, this goes on for a few cycles. Next step start with reminder to check fluid ? why nothing has been opened yet. Now the real work starts, pedal operator pumps the pedal a few time, we did 3-4 - Line one, Each wheel goes throught at least 1 cycle of pump brakes 3 times, hold pedal depressed Open bleeder let open till liquid stops flowing, and it clear of bubbles. repeat as many cycles as required. This goes on for RR, RL, FR, FL. ( we did 3 cycles on each caliper) Then with foot still on pedal I open the bleeder screws. 10 mm wrench on the rear 8 mm wrench on the front the cycle gets repeated for each wheel : After line 1 is done you start all over for the Line 2 !, but between those steps the car does a Actuator bleeding : - Line 2 bleeding start, Identical to line 1 all over again !, here is the RL slide, When the Line 2 section is finished running around opening bleeder screws is finished the rest is all internal : Noisy stuff and alarms start going off in the car. Pump cycling and valve adjustment, 6 cycles pump is noisy all sorts of alarm and light go off on the dash. It spends allot of time, doing 6 cycles of this step. Asking for Fluid check Valve learning part Lights on dash light up again : Done ! Total fluid used about 500 ml, and you to be two , or use a rod to keep the pedal depressed when it calls for the bleeder to be opened.
