ive got everything all put together and the reservoir is full, and when i pump the clutch pedal i get no pressure, at all, and it does not use any fluid. its a brand new master cylinder from napa autoparts.
Are you using it? Fill the reservoir with fluid and press the pedal up and down until the bottle is nearly full. Keep the reservoir high on fluid at all times. Then repeat. If the pedal does not stiffen up after pumping the pedal up and down several times, then check for a fluid leak.
