[Healeys] Unbalanced Rear Brakes

[Bob Spidell]

Couple SWAGs:

- something restricting flow to the wheel cylinder?

- Healey drum brakes use a 'servo' action, where the leading shoe pushes against and assists the trailing shoe.  If the 
wheel cylinder can't slide easily this could be impeded.  Check that the wheel cylinder can slide easily in its slot.
