clutch engages only after complete depression of clutch pedal on 2003 Toyota Tacoma

I just inherited my father's 2003 Tacoma; the clutch seems dysfunctional. There is adequate fluid in the hydraulic cylinder. How do you adjust clutch engagement?

hydraulic clutch is engaged by a slave cylinder the depresses the pressure plate. It does not adjust like a linkage type clutch. look in the inspection cover in the bell housing look for signs of fluid leak if not you probably got air in the system and you need to bleed it simular to bleeding brakes. If that dont work the clutch master cylinder may be bad it can be leaking internally the fluid is pushing past the seal and not making pressure to puch the slave cylinder.
