Bleeding the Master Cylinder

Hey guys, i got a new clutch slave cylinder and last night i had a bit of problems.
i would have to push on my clutch pedal a few times for it to build pressure, then a few minutes later, it will loose pressure and have to push on it again for it to tension Up. Now i'm lost of ideas, becasue it does build pressure but then looses it again.
I did bleed the clutch and did everything i was told to. I think the master cylinder might need bleeding as well.

Let me know what your ideas Are.

Also, when i open the bleede nipple on the Slave cylinder and pour fluid in the reservoir, it bubbles. (gravity bleeding) dunno if that helps, but let me know what you guys think

Cheers

BLEEDING M1351001400284
CAUTION
Use only brake fluid DOT 3 or DOT 4. Never mix the speci-
fied brake fluid with other fluid as it will influence the brak-
ing performance significantly.
.
MASTER CYLINDER BLEEDING
The master cylinder used has no check valve, so if bleeding is
carried out by the following procedure, bleeding of air from the
brake pipeline will become easier. (When brake fluid is not con-
tained in the master cylinder.)
1. Fill the reserve tank with brake fluid.
2. Keep the brake pedal depressed.
3. Have another person cover the master cylinder outlet with a
finger.
4. With the outlet still closed, release the brake pedal.
5. Repeat steps 2 − 4 three or four times to fill the inside of the
master cylinder with brake fluid.

Bleeding the clutch master is the same procedure as bleeding the clutch slave. It has its own bleeder screw. Open screw and push pedal -> close screw -> release pedal. Repeat until all air is out.

Either there's air in your lines or you need to adjust the clutch pedal.
