Something I forgot to mention, could be helpful to other readers too.
You may already know this, but check the accumulator on the hydroboost unit. It’s the only part not available separately. You can get reseal kits for cheap all day long but nobody I found sells the accumulator by itself. It only comes on reman units.
You have to compress the unit in a vise to remove the snap ring retainer for the accumulator to come out. Once it’s out, it should be very difficult to move the accumulator piston even a small amount. Like put it in the vise difficult. If you can do it by hand, it’s toast.
