The 23/25mm Master Cylinder has a hard enough job providing adequate pressure for larger fronts, let alone calipers on the rear too.
Has anyone actually got an answer as to WHY though.
You look at any comparable car. A Mk2 Astra GTE 16v for instance, we all know how rapid they are, and they have big old brakes up front and discs on the rear, and a 19mm master cylinder IIRC.
Fords seem to have massive master cylinders and consistently shit brakes
WHY???????????
