Movit Caliper rebuild

[flashyg]

My dust boots / dust seals on the movit 6 billet calipers are not perfect so I have decided to look into replacing the odd boot.

Questiin.1
On these calipers are the boots the type that simple prize off?

OR

Do you have to withdraw the whole piston to get the boot off?


Questiin.2
Any one know the size of each piston as they are all different

something like
32 34 38
34 36 38
30 34 38

Not sure.
Thanks for any expertise.
