I read a number of posts, plus Haynes and the service manual, on bleeding brakes and the clutch.
I do not understand if the car needs to be jacked up and level - if at all - or if one end must be raised at a time. e.g. Haynes' 9-15 step four says the rear bleed valve must be tilted to 11 o'clock (meaning to tilt the car I presume) to prevent air entering the system. so I don't understand what that means if all brakes are to be bled.
also was wondering why the clutch is particularly difficult to bleed, as was suggested on some old posts.

sorry. bleed every other year at least and your brakes/clutch cyl will
last almost forever. The clutch doesn't bleed very well because of the
type of master cylinder - trust me on this - just get or borrow a
pressure bleeder

what about the level of the car - will it be OK level? i.e. is Hayne's incorrect?
regarding bleeders : there's some interesting home-made bleeder how-tos out there like:

useless, or wrong. You can get a PDF of the original manual, just
search the internet, and Porsche on their web site has a PDF of the
master parts list. If you use a pressure bleeder, leveling is unimportant.

I'm looking for a cheap (i.e. free) cap for the brake fluid reservoir so I can make a pressure bleeder. any ideas appreciated.

for the clutch cylinders, will pressure on top of the brake fluid reservoir do the same thing as pressing the clutch pedal?

also I read somewhere that pressing the pedals during bleeding can scrape junk out of the cylinders because they travel further than they do under normal operation - is this nonsense?
but related to that - is there an optimal position, or should one operate the pedals at some point while pressure bleeding to clear out the cylinders?

car opening the bleed fittings, don't worry about it, just get the junk
fluid out of there.
