Replacing 80 series brake calipers

[a80crewza]

Hi guys,

I'm gonna try to replace both my rear brake calipers on my 80 this weekend if the weather permits..Is this a difficult job? I've got a haynes manual to follow.. If I replace just one caliper at a time, then do I only need to bleed that one, or does the whole system need bleeding?

Replace both then bleed them together.
Rhs first then the left
