vectra c 1.8 clutch problem

[td_dan]

hi, before i start there wasnt a miscellaneous section so thought id put it here, please feel free to move if need

right my mom has a vectra c 1.8 petrol, it was very difficullt to get into 1st and reverse, find if you turn the engine off just wouldnt when on, did some reading and looked like the concentric slave cylinder so stripped the box and and changed the clutch and slave cylinder and put it all back together.

problem is it still having problems going into gears, iv bled the hydraulic pipe but noticed when i press the clutch pedal the box isnt drawing any hydraulic fluid. I removed the lid of the brake reservoir and blew into it and can feel it at the bleed nipple on the box so theres no blockages.

anyone have any ideas on what it could be?

thanks for your help in advance
