Hi. A while back I replaced the M/C on Vitesse with a Landy unit, plastic cap Iv'e just realised has no breather hole. Clutch seems to be working ok. Is this ok?.

Also does the fluid level in M/C drop a clutch wears?.

Cheers, Dave

The plastic cap will have a breather somewhere in its double skin top cap may even breathe at the thread sides

 

Dont  quite agree with Colin , its static slave as the clutch disc wears the slave piston position  will change and depends on design raise or lower the   reservoir due to small changes in  system  volume

Hi,

 I would have thought that the dynamic absolute pressure inside a "sealed" master cylinder was influenced more by temperature than wear or movements of slaves?

Most caps I have seen did have a pinhole but I suspect the flow thru is restricted by the skins & seals as Pete says.

Cheers,

Iain.

Sealed for life the basics are similar seals pistons etc but some dont have a reservoir as such , some use a gas and diaphragm to seperate air from  fluid,

some come  to  bits .......some are mend to destruction  ,   and they are nearly all ,just plastic.

Not made to be played with ...
