I was having to much of a nice day.

Came back from work in my B and 2 km from home the clutch pedal stayed on the floor. Leaky hose..NO..Stuck piston fully depressed.

I knew things were going to well.

I will thus change the clutch master cylinder, the flexible hose and the slave cylinder. /ubbthreads/images/graemlins/mad.gif
 
The good thing about owning a B is that, once you've fixed all the problems, you've got a new car /ubbthreads/images/graemlins/smile.gif! No matter, I still love mine!
 
Mine keeps sticking closed. Tell you what, I'll send you one of my cylinders and you send me yours, and we'll split even out and both have good clutches again! /ubbthreads/images/graemlins/jester.gif
 
This was a major PAIN to change. the only easy part was the slave cylinder. The hose (lucky for me) required serious tools and an impact gun to remove.

The Brit who designed the pedal box must have been a complete idiot. Removing and installing the new clutch master cylinder was very time consuming.

Everything is installed but it seems to be impossible to bleed the system byt myself. Will try again tonight with a helper.
 
Well I got my car out this morning and works fine.

I do have to share my experience with the bleeding of the clutch system. It took me about 1 gallon of brake fluid to bleed the system (no joke) and even then it would not operate the clutch properly. I was getting very tired of this and then had an idea!

Why not compare the old slave cylinder with the new one..AH! the bleed niple and the brake hose were inverted.
It's my fault I should have compared the 2 side by side. Probably at the factory the worker just screwed in the bleed nipple in the hole for the hose.

Changed the things to the proper way. Bleed the system in less than 2 minutes. Clutch works fine.

Boy I feel stupid for working like an idiot.
 
Oops forgot...

By the way I found exactly why the clutch was staying open.

The slave cylinder was full of rubber bits because the rubber hose simply was disategrated from the inside pushing bits into the slave cylinder. /ubbthreads/images/graemlins/driving.gif

Sure, it may seem idiotic now that there is no dealership system, but back then I'm sure it kept the service department dollars (or pounds) rolling in.
 
Hello,

I am jumping in on an older post as I have just joined this forum.

Eric, do you think you could have cleaned out the slave cylinder of its rubber bits, replaced the hose, and saved the original hydraulic system? I am having a similar problem with the clutch pedal being intermittently stuck engaged and resisting slightly when depressed and am wondering if I can avoid purchasing a rebuild kit. They don't cost terribly much so if it doesn't sound like a good idea, I will buy the kit.

This B had a similar problem with a brake caliper due to a disintegrating hose. Of course, the hose was only discovered after a new brake caliper was purchased and installed.

Thanks
 
The slave cylinder I replaced also had the bleeder reversed. I don’t know why they do that unless it saves them a few seconds per cylinder in the manufacturing process.
