Classic Mini Wheel Cylinder Rear 5/8 Diameter Reproduction

The other 4-way valve on the bulkhead on later cars (part number FAM7821) is frequently wrongly identified as one of the above as they are similar. However, this unit does not have the electrical connection, and has a cylinder sticking out one end. This IS a brake pressure regulator, only fitted to front/rear split systems as far as I'm aware. The PDWA is built into the master cylinders in these applications.
