What is the correct size for the rear brake seals, looked online and there are two different sizes. Need to try to free up my rear pistons and anticipating worse case scenario.

I can't help with the size, but possibly with the seized piston.
I used my grease gun. Once the nozzle was removed I could screw the end of the flexible into the brake fluid port.
Use the bleed nipple to bleed air until you get grease out.
Then the grease gun gives very controlled pressure to shift the pistons.
The problem is that once one is moving you cant build pressure for the other.
I pushed the moving piston back in, held it with a piece of wood and was then able to free the second piston.
Sounds complicated but worked for me!

Any update? What size and where did you buy your rear brake seals?

Haven't got any yet but have found that if the front of the car stops the rear does also. It will be sorted tho'
