Product Details & Fitment
Part number RH2588 is the genuine 5/16" to 3/4" union conversion kit for Rolls-Royce Silver Shadow I and Bentley T1 models from 1965 to 1972.
From approximately VIN 12400, the diameter of the solid pipe between the brake pump and accumulator was increased. The high-pressure pipe union fitted to the brake pump was also increased from 5/16" to 3/4" as part of this later configuration.
This conversion kit provides the components required to update the earlier brake pipe and union arrangement to the later 3/4" specification. It is intended for vehicles requiring the larger union and associated pipe configuration.
Please verify the vehicle VIN and existing brake pipe and union configuration before ordering to ensure correct application. Professional installation is recommended when servicing high-pressure brake pump and accumulator components.
