If the pedal is changing engagement points they probably don't have it bled right or the master cylinder is failing and causing it, We always recommend a new master when the slave or clutch is changed. Keeps this from happening after the work is completed. A lot of times when you open this hydraulic system the original clutch master no longer want's to work correctly.
