Martindale}1/MH.{M. Huckerby}25.5.38. HYDRAULIC BRAKES B.56.BN.{W.O. Bentley / Mr Barrington} As the non-servo brakes on B.56.BN{W.O. Bentley / Mr Barrington} were not completely satisfactory we are rigging up the car to have servo assistance to front brakes only, rear brakes direct operated. Will you please transfer the equalizer from the O.S. of the rear axle to the N.S. (similar to O.B.IV and 3.B.IV) and add the non-wrapping links in the rear brake assemblies.
