1984 VW camper T25 has no clutch?

a 1984 Volkswagen T25 camper van, 1.9 petrol, While driving, the hydraulic pipe on the clutch burst, I replaced the pipe and the clutch slave cylinder, and bled all the air out. But now the clutch doesn't release. The release arm and slave cylinder move ok, about 3/4 inch, there are no mechanical noises.
