To brake with a servo brake system where the servo has failed is absolutely
not the same as to brake with a brake system, which has no servo equipped at
One cannot compare.
A brake system where the servo is in malfunction is very hard to brake
A brake system without a servo works normally very well on a MGB. (I've got
the US spec tandem master cyl type).
I know this of experience, of one occasion, when my regular car's engine
stalled and the servo lost it's vacuum. The car was running still on a
crossroad - with no control.
Brakes were almost not effective - most dangerous situation.
