It's best to replace the master cylinder because the bore can get pits and scratches and if honed out to far the cup seals won't seal. It is also a good idea to replace the slave at the same time because the dirt is pumped to the slave and damages the seals in the slave. The slave is a little more forgiving because it is steel not aluminum as the master. The slave cyl. can be more successfully rebuilt. You will have to bleed the air out and this can be difficult at times.
