As for the original question, as others say, there should be a pressure limiting valve on the rear subframe, but if it works without one, who knows. Every mini is an individual! Wheel/tyre can influence lock-up greatly.
The limiting valves were in short supply recently but seem to be coming back. If you check on the Mini Spares UK website, there is an explanation of which valve fitted which cars in the UK at least.
21A1774 was the valve for UK mk 1 & 2 minis and Cooper S (5/8 inch cylinders)
21A2031 was for most minis with 3/4 inch wheel cylinders.
They are around $200 mark, but generally lasted well.
The only difference was the internal spring and both springs seem to be available too.
