Hi Sandun, here is a link to the Moss site which has a schematic and lists all the parts you require.
Yes the cylinder should have a rubber boot and should be able to slide up and down.

Have you downloaded the workshop manual?

Sandun
The cylinder itself does not have a rubber boot like the front brake cylinders. Dust and dirt is prevented from entering the cylinder by the piston with dust cover (BMC Pt No: AJA5008) which has a dust seal which fits inside the cylinder.
The rubber boot (part of item 59 in the above link) (BMC Pt No: 7H7943) fits over the cylinder pipe union and to the rear/outside of the brake back plate.

The correct rear brake cylinder for your car is posted in the link against the chassis number for your car which I believe is Pt No: GWC1111 (MOSS) (BMC Pt No: 17H3685)

Don't forget to reassemble the cylinder with some brake grease, helps preserve the brake cylinders 8)

Hi Sandun, you can fit the later wheel cylinders as the difference is the bore size of the cylinder, the other dimensions are exactly the same.You must though replace them as a pair otherwise the rear brakes will be out of balance.
Personally I would replace them with the correct size for your year of car. (57-62)

Hi Sandun, it's normal. When the brakes are adjusted correctly It only needs to move a small amount.
