you can do the repair, and then just take it to the shop and have them do an automated bleed.
If you bleed the brakes manually "the old school way", they will work fine and feel normal. BUT if you slam on the brakes and the ABS kicks in, air will suddenly enter the system (as the solenoids and valves open/close) and the pedal will drop to the floor and you could lose your brakes.
So if you replace the BPMV, bleed the system normally...then just carefully drive it to a place that has a Tech 2.
You can kinda "ghetto bleed" the BPMV without a Tech 2, but its obviously not desirable/correct.
To do that...bleed the system manually so the brakes feel fine. Then go find a long straight dirt road (or snowy road, or something thats slippery), get up to speed, then slam on the brakes so you get a good long several-second-long ABS activation. The brakes will then feel really spongy, like theres air in them (because there is).
Go back and then bleed them manually until they feel good again. Then go out to the road and get ABS to kick in again. Then do it all over again.
That will probably get you 90% of the way there to what a Tech 2 will do during a real automated-bleed procedure as far as getting all the air out of the BPMV. You will know when you've gotten all the air out of the BPMV by how the pedal feels during an ABS event. If all the air is out and its properly bled, when the ABS kicks in, the brake pedal should not drop to the floor, it will stay firm and push back at you.
