I had the same problem, my hose burst just before the slave cylinder on the rubber part of the hose.had to take the whole pipe out to have it repaird.what a mission.thanks for video was great help.
This is great info. How did you know it was the master and not the slave cylinder or the line from the master to the slave? I'm trying to determine the cause before replacing the wrong part.
Good question, for me this has happened before, probably due to the sachs paddle clutch springs being super hard and accelerating wear. If it was the line I hope i would see fluid leak. From there it's 5050 as to which end! The slave side looks way more difficult to change and get right. Good luck!
Hello Munsie, hope this finds you well. Thank you kindly for this video on the master cylinder and other great videos on the B5 platform I enjoy your videos and they’re very helpful. I have a B5 S4 sedan, and like you I’ve been keeping it going. I was fortunate when I worked with, and Indycar Team that the techs help me set it up, but since then I’m doing a lot of work on the car. I’m wondering if you have any videos or insight on how to change the clutch slave cylinder? I’ve purchased a replacement. I see the slave cylinder is viewable from the top of the engine where the transmission is I’m not sure if I could replace it from the tub, or I would have to drop the axle as you did in your video. Wondering if you have any insight, which I greatly appreciate. Thank you.
Hi, not had the pleasure of this task, yet, looking at the Bentley manual is suggests getting at the clutch slave from below. It wants you to remove drive shaft, CV joint heat shield and transmission support to get proper access to it! Then you'll need to wrestle with the hard line and when installing the new one be careful to make sure push rod seats into release lever properly. If you DM me on Instagram I can send you the Bentley chapter on replacing clutch slave cylinder...
Thanks, no idea for 2012 A4, Have a look around the clutch pedal and see if you can see a piston like switch with wires coming out of it with a rod that depresses into the switch itself when the clutch pedal is up? Weird things happen when this switch is faulty like the idle increasing randomly when you are stopped at the lights.
@@munsie888 thanks . my issue seems to be having to push harder and higher on the clutch pedal when starting .which makes me think a switch is staring to fail. did you get rid of your 1999 A4 in the end?
The hardest part of this job is getting the clip to come out of the clutch pedal. Original matter had a broken clip so it fell out. New master won't allow the brake hose to seat all the way so i have to remove it. I've been on my back 4 hours trying to get it out. Any tips?
If you are talking about trying to push the hardline into the new master cylinder, yep, it's super hard, check the video again. I think I use some tools to apply leverage to the hose to pop it in.
I am trying to change the clutch master cylinder on my Audi A6. The arrangement seems the same. So far I have removed two hex bolts holding the clutch master cylinder and the hex bolt for the pedal box. I have pulled out the metal pipe which has the clip and also removed the Mystery bolt (T45 bolt) near it. However I can not seem to move the peddle box. Do I need to also remove bolts on the brake servo in order to be able to move the peddle box?
Not sure what plugs you are talking about? Normally you apply slight pressure to the whole connector pushing it in then slide or push the release tab towards the connector then pull apart. Stubborn release tabs may need encouraging with a small flat blade screw driver...
I’m trying to replace my hard slave line that goes into the master cylinder through the fire wall. No matter what I do the slave line just won’t come out of that whole even with the clip entirely off. Did you need to do anything else to free that line?
With thr metal circlip off you'll need to wedge a piece of wood or long spanner with a rag wrapped round it between firewall and hard line and lever it out of hole/master cylinder. It requires some force and will pop out with a bang! When you've popped it out make sure the black ferrule/olive on the end of the hardline is present and not damaged. Same goes for insertion. Good luck.
LHD B5 1.8t here. Your video saved me! Obviously everything is backwards on my vehicle, but your video made great reference for me!

I had the same problem, it was my line from the master to the slave, the little rubber part on the end was inside damaged.
awesome work very detailed
keep it going sir 500 k
Bloody Helll ,lots of fun!

@@munsie888 Thank you!
Awesome, I've got the same problem on my audi b5 1.8 , can I also use the same method, I see the engine looks the same.
Probably, watch the video and if you have a similar hydraulic clutch setup then most of it will apply!

@@munsie888 thank you kindly, I will search for you on Instagram and message you, that’s really nice of you, I really appreciate it. Thank you.
great video .
would you know is the clutch start switch built into the clutch master cylinder on an 2012 a4

Yes, there should be two torx bolts holding the brake servo onto the firewall anchored by the pedal box, see 7:46
How’d you disconnect those damn plugs man to get to that nut?!
