Vixen 2500 Clutch Hydraulics

[yosini]

Hi all,

I spent a very happy lunch break today under the Vixen, managed to change the slave cylinder without any issues. However, when it came to bleeding it there were constant air bubbles being introduced along the pipe from master cylinder (some clever PO had installed a transparent tube between master and slave - genius!). I eventually ran out of brake fluid to top up with so left it at that. Took it for a drive and much improved, I can actually select gears now! but the clutch biting point is still just off the end of the pedal's travel to the floor. There were three holes to put the clevis pin through at slave input shaft end, I went for middle - does this serve as the 'adjustment', it's a pretty heavy clutch too, especially in lunchtime traffic. At least I also managed to test out the cooling system - lots of traffic, central London, scorching day, fan over-ride on and kept happily around mid-gauge. Goody.

So, questions:
Do I need to replace the master cylinder too or look elsewhere for bubble generation?
Is there a clutch adjuster, or am I likely to need a new clutch plate too soon?

Cheers

Thanks - I'll start with the actuating rod and put the clevis pin through a different hole to see how that alters the pedal/clutch feel. The slave I replaced was a 1 inch unit and the master looks to be a similar bore, maybe I just have a weak leg....

ah, there was me thinking the transparent pipe was clever allowing easy spotting of air bubbles....but yes, that makes a lot of sense. I've had a look on Rimmer Bros website and it looks as if there are two options for the Master cylinder bore - 0.75 and 0.7 inch - think I'll get a smaller one unless anyone foresees problems. I'll change the pipe out at the same time then too.

Thanks all

Thanks Alan, that one piece hose looks good - do you know if that's the correct part number? ie is it long enough?

Cheers
