[Healeys] FW: BJ8 Brake servo problem

[Michael Salter]

Hi John,
There are usually only 2 models of PBR servos used on Healeys the VH44 and
the VH40 I believe I may still have a kit for a VH44 which from memory uses
an 8" diaphragm. I think the model number should be on the unit somewhere.
They are very easy to rebuild and sometimes you can do so without even using
a kit.

I have a 65 with a servo that is not original, I think it's Australian.
Patton's Brake Replacements (PBR).   Recently the engine runs rough when
brakeing.  At idle the engine idle speeds up slightly when brakes are
applied.  I think the problem is with the servo affecting the intake
manifold.  Any one have experience with this? 

Can the servo be rebuilt?
