Bill there are several threads on this subject, but provided you have the capabilities of a contortionist, it shouldn't be too difficult.

The master is at the top of the clutch pedal behind the panel which has to be released by taking the two lower screws out then wrenching it from the grips at the top.

To assist in turning the cap on top of the master, it has been found helpful to assist it's anti-clockwise motion with the use of a hammer/mallet and large flat headed screwdriver to tap it round.

Inside one should find what is referred to as a condom, this must be removed to check and/or replenish with fluid (which I understand to be Dot4). Using a finger feel for the level, and start with only filling halfway if it needs it, as the condom will have to be refitted. The test for you, if you accept, is to use something akin to a syringe or tube to place fluid into the top of the master - blindfolded.

A Haynes manual is really useful for a guide but not always 100% accurate, especially in this, the brake fluid reservoir does not replenish the clutch system.

Good luck

As you've not been back with any news, how are you getting along with your problem ??---( The clutch master is just behind that blue collar. )

Question Yet more Clutch stuff!

I have been considering doing something similar with my 75 which has air in the clutch hydraulics. I can use the car but have to keep pulling the pedal back up otherwise I haven't enough clutch to disengage properly.
I propose to use what I believe is a clutch bleed off - a stiff pipe with a nipple on the end which sits just in front of the battery.
I would use a technique I have used to bleed the brakes on my bike.
I start with a large syringe half fill with Dot 4 and connect to the bleed pipe using a suitable clear plastic tube. Next, squeeze air out of the tube so it is replaced with Dot 4 from the syringe. Next, open the nipple and similarly expel any air up the tube as above.
Then I get an assistant to sit in the car and slowly press the clutch pedal noting how much if (hopefully) any air bubbles appear. With the pedal fully depressed wait until all these ? bubbles have risen into the syringe then have my assistant slowly let up the pedal whilst applying pressure with the syringe plunger. Job complete, pedal back in position nip up the nipple and remove tubing etc.
Question is, fellow Forum users, will it work?

If it was me I'd whip the master cylinder off, strip it down and give it a good clean out. Fit it back, bleed it and see how it goes.

Here's my new clutch fluid reservoir.





Unfortunately, it's still not in operation.
The problem is connecting it to the pedal without drilling any holes.

As time goes on, I suspect I will succumb to that.

Quick Release from a scrap slave & Gunson Easybleed.

All seems good so far - daft thing to say......
