Routing of the clutch hydraulic system

Post by thomas_m535i »

I'm trying to reassemble the clutch hydraulic system. Unfortunately, the original parts (hose, lines etc.) were lost. So no examples available :(.

I took some pictures of the current situation this evening (apologies for the quality). Is there someone who can help me out on determining the correct routing of the hydraulic lines (from clutch master cylinder to clutch slave cylinder at the gearbox) with these pictures? And also where the clutch line bracket (see picture) should be mounted?


Your advice is greatly appreciated. Many thanks in advance.


Thomas

I might be able to get some pics; meanwhile, the rubber line connects to the master cylinder, the other end goes into the hard line which is supported by a bracket if I remember correctly.

Peter, thanks for your reply and offer. You're right.

Using the right bolt this time for the bracket :-) and with some copper wire to do a bit of trial and error (to correctly bend the hard line), it turned out to be very straight forward: the pressure hose should indeed be attached to the master cylinder. The hard line goes into the slave cylinder. The clutch bracket is mounted on the engine. I will see if I can post some pictures of the result.



FYI: for those of you which need to do some work on the clutch hydr. system: the master cylinder nuts are very hard to reach with the brake booster etc. in place, but it can be done. If you're planning to replace the plastic 'elbow' in the master cylinder, it's best to do this when the master cylinder is removed.
