[Healeys] Dual Brake System

[Peter Linn]

G'day Ron

I had to put dual circuit brakes on my V6 engined BN1 for compliance here in 
Oz. the car has original (5 stud) drums on the rear, Wolseley 6/110 discs on 
the fornt (calipers are similar to 3000) I've used a Datsun 240/260/280Z 
master cylinder (7/8" bore) with a booster acting on the front only. 
Although I have yet to use the car in anger, all seems to work pretty well 
so far.

Cheers
