[Healeys] Brakes -rear wheel cylinders

The 100-6 had drum brakes.
The BT7 was fitted with discs and Type 14 calipers (7/8” dia. pistons) paired with 3/4” rear cylinders.  That is the way to go.
BJ8 used Type 16 calipers and also 3/4” rear cylinders. That is also good but gives slightly longer pedal travel. BMC compensated by increasing the Master cylinder size and adding a servo. Not strictly necessary but gave good results with lower pedal effort.
You pays your money and take your choices.
If you stay with 1” rear cylinders the rears will lock under hard braking and potentially cause you switch ends.  Not recommended.
