the master and slave cylinder are a built in unit,there is no cable between them. there are piston'fluid connected. you can buy a rebuild kit for $9.00. But it is much better to buy a rebuilt master cylinder than try to rebuild it. Especially on ABS master cyclinders.
You need to replace the rubber seals in the master cylinder. May even have to have the master cylinder re-sleaved.
If you need to replace the slave cylinder it is located in the bell housing and the trans has to be removed. The clutch master cylinder is located on the firewall on the drivers side
