[ROVERNET - UK] Brake servo rebuild(s)

Hi Eric,

I think I'd like to take a shot at rebuilding them myself. Once I have them 
apart I can check on the condition of the cylinder walls. If they're okay I 
can just use the rebuild kit components. If the walls are n/s I can get them 
resleeved here in Brooklyn, most likely.

As for the 'shiny nylon bits', what would you recommend? I'm guessing the 
nylon will be fairly brittle after 38 years of service and I'll have treat 
them with kid gloves. I'll give Ruth a ring today.

Shame about the brakes I was really looking forward to driving the Rover 
with the sorted clutch. It's good I found out now and not at 70 MPH I 
suppose!

Thanks,

Steven
