Brake Actuator Replacement Time: C1256 & C1391

Looks like my brake actuator needs to be replaced. I looked at a bunch of guides on here on PriusChat, and it appears that this is a doable DIY project, although it will require quite a lot of time, patience, and bleeding the brakes once the procedure is finished.

My question is this: what are my options? My car is salvage title so the warranty isn't applicable. I contacted my local dealership and am waiting to see what their labor quote would be if I installed a used part that I provide. It looks like the tools required are simple sockets/open end wrenches, and for some reason on one of the guides provided, clamps to what I assume is keep brake fluid from draining once this thing is removed.

The plan is to replace the part, and have the car towed to a garage to have the brake fluid professionally flushed/bled. I could consider flushing the brakes myself, but I don't trust that kind of work to a first-time DIY.

Anything I should be wary of regarding the used parts I want to buy? My main concern is possible contamination from whenever the part was removed/stored.

Next question: isn't the actuator interchangeable between other Toyota vehicles? If possible, is it possible to purchase an actuator for a Toyota non-Prius at a possible better price and less mileage/wear?

Lastly, I'd love to hear what other's experience has been replacing this part. I know there has been recent talk of a class action lawsuit, and I was wondering how to participate as well as document this repair for possible reimbursement down the road, because apparently this part should be outlasting the life of the car in the majority of cases, which appears to not be the case given the recent uptick in issues.

 

The guide that I looked at shows that you can just place the inverter to the side and still have enough clearance to replace the part. I'm planning to do that in order to avoid changing the coolant.

Now I'm just waiting for the hybrid battery to start dying; thankfully as battery technology gets better and more hybrids/EV's are put on the road, by the time that happens it should also be a relatively affordable repair.

 

I was able to do it myself. If I had the option I'd have a friend with me to help carefully lug the inverter in a nice secure resting position with some padding to avoid scratching. I just made sure that the hoses experienced as little stress as possible and didn't rupture.
