clutch pedal

[viinnh]

help me please.
I changed my master and slave for clutch today. I bleed the lines already to the point where it pisses out fluid from the nipple like water flowing outta a tap. the clutch pedal is like normal when i press it in and keep on pumping it rapidly its really hard like how it should be (heavy duty).
But when i stop for about 2 seconds it looses pressure. would you know what is wrong ?? and if i pump it rapidly again it goes to normal. with in 2 seconds with out pumping it, it looses pressure

If it's not leaking fluid then you have air in the master cylinder or lines

ive bled it heaps of times already went through 2 bottles of fluids

btw when theres no pressure in the pedal. its just like having no fluid it drops down and doesnt come back up. i pull it back up and start pumping it gets back to normal

most likely a leak, keep an eye out for fluid, or it might be internally and the fluid is filling up inside the master?

can you explain how you bled it??

nah looked everywhere no fluid coming out
took apart the master had a tiny bit of fluid inside not much, like a few drips

can you explain how you bled it??

step in clutch. release nipple closed it, pump pedal a few times put pedal to the floor release nipple etc etc till it went hard from pumping it but then if i dont pump it it goes down

[SLOBRO]

ok try this leave the nipple open till it starts dripping fast then close it then check it

i actually did try that in the arvo. i left it open and got someone to pump the pedal while i wait for fluid to go down so i can top it up
once itstarted pissing i told them to put the foot down and i closed the nipple.

results same thing

there you go you can't pump it while the nipple is open man it won't work like that
+ what i meant was just leave the nipple open dont pump the pedal leave it open and let it drip then close it
and did u run out of fluid when your mate was pumping the pedal? if so you might have stuffed your new Master cylinder

Lol fail

Mate try this

Run a clear or somewhat translucent tube from the nipple to a bottle half filled with fresh brake fluid- make sure the end is BELOW the surface.
Open the nipple with a 8mm spanner , open the clutch reservoir cap and start pumping the clutch pedal by hand. Get
Your mate to monitor the reservoir and top up - keep pumping until a steady stream of fresh fluid fills the bottle. Tighten nipple, remove tube and top up the reservoir if need be. That should be it.

i have tried this as well same thing



guys after playing around with the clutch pedal this is what happens

press the pedal down hard it will be hard like a normal HD clutch
press the pedal down soft it would be like theres no fluid inside what so ever it just goes down and i have to pull it back up
