93 Saab 900 clutch.. no pressure

Replaced both MC & slave. Replaced fluid and and hose. Everything worked fine foe a few days and then back to square one. Clutch lost pressure and cannot get car in gear. Any suggestions, please? Thanks

It’s possible the new clutch master cylinder is defective. It does happen.

No doubt air has gotten back into the system. Does that car have the same annular slave cylinder that they used on the decade-earlier models? If so then it’s drawing air into the slave through its poorly-design seal. Bleed the air out again to find out.

Thanks folks. The replacement parts were purchased from a Saab dealer (does that mean they are a newer design? That I do not know)
However, I’ll start by bleeding out the air and get back with my results. Thanks.
