[Mgs] MGB rear brakes

[Paul Hunt]

Correct.  When cars like the original Mini had drum brakes all round and the
same cylinders they used a pressure limiting valve.  The MGB doesn't because
the brake balance can be set with the cylinders vs the calipers.  Modern cars
with discs all round achieve the same thing with differing caliper/piston
sizes or a proportioning valve or a combination of both, even with ABS, like
the Zed series.  You wouldn't want the rear brakes to be modulated by the ABS
with all that pulsing under your foot under 'normal' braking.

  It's not about the amount of fluid, it's about the force applied. With
  a larger diameter slave cylinder, the same pressure is  applied to a
  larger area, resulting in a greater force. Hence greater braking
  effort.
