Finished replacing booster/accumulator. Brake Bleed Next

Brake parts are things you should not buy used.
There is almost no way to know if the part was really working or not.
I would think that maybe the part is not installed correctly, which is why you can't depress the brake
pedal and the switch didn't line up correctly.

You could search the internet for photo's of the brake lines to insure you have them on correctly.
Another possibility is that techstream is not working correctly.

You need to contact the place you purchased those parts from and get your money back.
And I think it's time to go to Toyota with the vin number and get the correct parts, NEW parts.

Having "iffy" brakes puts innocent people on the road at risk, not just you.

 

The whole point is the housing number is not the part number. Every year hatchback has at least two different master cylinder (brake booster assembly) part numbers, one per tire size. A v wagon is different x2 as well. Used sellers don't know this and foul up guys all the time.

The pump is more universal but there is a bad design flaw in 2010 production.

AGAIN, you can't tell by the housing number. You have to buy new and include your vin. You could call one of the online dealers. Most walk-in parts departments won't help unless you buy from them, usually at full msrp. Most oem parts have a wholesale price 50% of msrp.
