When I push in my clutch I have to pump it a few times to build up pressure to work there's no leaks and its full of fluid and its been bleed and no air . And another problem I have is when I try to put it in reverse it grinds but if I put it in 1st then in reverse quik then it don't grind now I am wondering how to fix these 2 problems and if the 2nd problem is because of the 1st problem ? ? ? ? Any help would be great thanks

The problems are the same you could have a bad master cyl. or the slave is bad and i would start with the master cyl. one or both could have internal leaks. A quick way to tell but not always is to put it in gear and hold the clutch and see if it will start to release in a short time. Also check your adjustments like the pedal to the master and make sure you have almost no free play.I like about 1/16-1/8th".

I'm having the same problems as you now, and like before they suggest it's one of the cylinders, either clutch or slave master. Lately (this of course is after I try to bleed it) I've had to pump the pedal to build pressure. I am going to bleed it like suggested in the above post and see what happens.

The master and slave are new but I guess I could have just got a bad one . Would a bad master or or slave make it grind when I put it in reverse?

I just went out and did that test Ind I sat there for 6 mins with it in first and with the clutch in and it didn't move an inch and I made sure I was on level ground

As stated make sure the adjustments are correct. The grinding going into reverse indicates that the clutch is not completely disengaging. Do you get any noise when first pressing the pedal, as that would indicate a bad TO bearing and the fork has to move further to compensate for the worn bearing.
This is not a new clutch install is it? If so the disc might be a little too thick or not the right pressure plate, disc or T.O. bearing.
Last thought, check for a bent throw out fork.
