[Mgs] Advice wanted on MGB Brake Master Cylinder

[Dodd, Kelvin]

Roxter:

I hate to say this, but of all the bits on a 70-76 MGB I draw the line
at rebuilding the master cylinder.

I've never had very good luck getting the delrin spacer out, then you
have the dreaded clip to negotiate.

While new ones are still available, I just bite the bullet and install a
new one.
