They'll advise on lining materials and have done many, many Austin Sevens. I gave up re-lining my own clutches and brake shoes years ago, it's not worth the bother given they do it professionally at a cost similar to doing it myself.

I'm sure Saftek will do a great job but some of us run cast iron linings (sports spec). With my new lighter flywheel I needed new linings so had to make some.
First stop my trusty garage chums, who unfortunately had just had an oil drum full of old discs taken away, so I had limited choice.
Bolt the disc to the flywheel and start making it flat. A ventilated disc will make two clutch linings. First the outer one.
Then the real PITA job, parting through the middle of a ventilated disc. This task tells me that modern brake discs are made of very high quality and high strength cast iron. The second lining comes from the inner part of the disc.
Then finish your linings. I jig drilled the rivet holes using an old 1 1/8 flywheel as a template with a register turned on the back. Rivet "countersinks" have yet to be machined (lack of the right tool!)
Overall it's a horrible, grubby job and whilst I throughly sheeted up the lathe before I did anything I still cleaned it with a toothbrush afterwards.
Anyone fancying trying this will have a much easier time if they start with good old fashioned solid brake discs, thereby avoiding the brutal parting moment on the ventilated disc (it was so noisy it caused Mrs P to come out of the hosue and ask me to stop!)
