Hydraulic clutch fundamentals

not done it
but i did research it
with an eye on reliable OEM parts, easy spares and not needing to pull the box and bell should the slave cylinder leak.

but if i was going to i'd use 80s chevy s10 master 82-92
Clutch Master Cylinder For 82-93 Chevy GMC S10 Sonoma Blazer S15 Jimmy DV22M2 | eBay cut off the eye, thread and use a rose joint at appropriate length. bolt and spacer at peddle.
it has more or less the right angle of dangle to its mounting to work without the usual machined piece necessary for a 90 degree mounting wilwood style on a mopar

on the clutch end 3 series or 5 series BMW parallel mount pusher on the standard fork

id use the standard fork
a mopar truck hardend steel part on the clutch rod in the fork eye. don't need the fat washer and rubber bit if the peddle is not directly connected to the vibrating drivetrain

i'd build an angle iron bracket on the clutch z bar ballstud mount which is now obsolete
and id use this

to push my clutch fork.

A shoddy way to feed it with fluid, would be to drill and tap for pipe fitting a hole in the big section of the brake master cylinder side wall, well above the level of no juice but just below the level the fluid falls to at full on brakes.
that way if you clutch fails and pees out brake fluid your brakes will still work

run brake pipe or rubber pipe down to clutch master and fill/ bleed from the brake master.

proper way would be its own bottle or half shoddy way, a brake master with a top bottle = more capacity

but if you buy a bottle may as well get the chevy one

it may not work, i never got that far
variation in bore will dictate peddle travel to some extent. but keeping it all passenger car parts reduces the risk.. bus and truck parts would cause issues


cheap way in to a hydrualic clutch which avoids all the shimming and messing about with those expensive concentric slave cylinders. BMW and chevy dudes have tested this gear out in the millions worldwide for the last 20-30 years
