Thread: Series III clutch pedal solid

My guess would be the slave is rusted solid. Was the same on my series 3 when I got it - pulled both the master and slave, cleaned them out (was hard work getting the piston out of the slave but soaking it and driving it back into the unit eventually freed it up. Put it all back together and it worked well enough to drive it around for a bit.

That’s assuming you don’t want to spend any money on it. Pull them out and have a look, easy job, nothing to lose.

As above - my guess would be the master cylinder is seized (or both), but you can check this by opening the bleeder on the slave.

Thanks Homestar

That was pretty much what I suspected. If I can at least manager to get that free it will be easier to move. I want to move it to another shed so I can strip it. I found a replacement chassis but again nothing going to happen till I get an income.

The rear brakes don’t work as the rust has destroyed all sorts around the rear.

Thank JDNSW

Certainty worth a go.

For wheel cylinders and slave cylinders etc. that are seized, placing them in a warm oven get's them to free up and "pops" the piston out.
Best to have them in a container though so that they wont splatter crud all through the oven...something like a large Coffee or Milo tin with the lid on it, but holes punched in it, so that it won't "pressurise" and blow it's lid off. Start off with low heat then turn the wick up a bit at a time till it does the job, rather than go in full boar with loads of Celsius

Cheers, Mick.

Excellent thanks Mick, sounds like a great idea

As well as the slave cylinder the flexible hose may have grown over , you may also find being a beach vehicle the clutch plate may have rusted to the flywheel & pressure plate assembly.

Thanks 1950landy

I had thought about clutch/pressure plate rust, and that’s why I mentioned the previous owner had driven it around his farm (long after it’s beach life). But still a real possibility..
