A pretty straight forward job but just double check the condition of the master cylinder bore before you put the new seals in.

The reason I say that is I've had a few tandem cylinders in with very badly rusted bored which would have ruined a new seal kit in next to no time.

Fortunately, Classicar Automotive in Cheshire put a stainless liner in it and pressure tested the cylinder for me.
