Hi

Got no pressure after mastercylinder change tried different ways but no joy please advise. Slim

Did you only change the master cyl. or did you do the clutch plates too.? Did you fill and prime before you attached the cylinder.

Hi i changed the mastercylinder and pipe.

First bleed the master

Pump it a few times, hold the lever in and crack the banjo bolt, do this until you get no air

Remove the slave, press the piston all the way in and put a clamp on it

Then bleed for about 10 hours til you eventually get the hose free of air (total pain as the master flows very small volume)

If you have a vacuum bleeder you could suck the fluid from the master down to the slave which works a lot better

You just need 3` of clear hose attached to the slave. Have the hose held straight up past the handle bar level. 5- 20 minute job. Bleeding does take patience.

See above link. As you can now buy vacuum bleeder kits for well under £20 there is no reason not to have one.

Regular changing / vacuu bleeding of brake and clutch fluid prevents a lot of the problems you read about on TC

I have found my vacuum pump sits on the shelve as the long tube works the best. Give it a try, I laugh at the hours I used to spend doing it any other way.

Vacuum bleeder isn't really neccesary, but you still start at the beginning and bleed the master, if it's not pumping fluid ...............
