Clutch Master Cylinder

[Proximity Motorsport]

Hey,

I have a RB25DET in my R32 GTS-T and its got a greddy copy plenum on it and it wont clear the clutch master, so i have put an r33 one in. Its brand new from nissan. I have bolted it to firewall and its connected the fork to the clutch pedal. I have filled it up with fluid and cracked the bleeder down the bottom and nothing came out, so i tried to take the bleeder right out and no good. So i cracked top bleeder and nothing... so i took the hydraulic hard hose off and still nothing, i looked inside it and nothing blocking it!!! So i put some vacuume line in and cracked top bleeder, and air is going from bottom through to bleeder... now im completely stumped as to why no fluid will go through the bottom hyd lines!!

any help is greatly appreciated! thanks

Had the same problem recently. Try this.

Adjust the piston travel to the master cylinder under the dash. If your issue is the same as mine the piston is too deep in the master cylinder and is blocking the bleed hole. Screw it so the piston goes back toward the drivers seat. Take it out a good distance at first and see if that cures your problem. Once you have fluid flowing you can bleed and readjust accordingly.

Hope it works for you. It did for me.
