I replaced the slave cylinder to try to fix it. After that didn't work we replaced the master cylinder. Went through and entire quart of hydraulic fluid bleeding the system. All else I can think of is the line but am not sure. Nothing looks wrong with it. If air is getting in there I have no idea where or how.
