This original metal canister master cylinder with Lockheed embossed on the can part has been available from us since August 2003 and are manufactured to OEM specification part number and as such are homologated for use on original specification vehicles using DOT 4 or 5.1 hydraulic fluid as specified in the vehicles hand book/workshop manual. These cylinders are not homologated for the use of any other fluid. This includes racing fluids such as Castrol SRF hydraulic fluid.

Now in a glossy silver colour-The reason for this is that all products must be free from Hexavalent by 2007 which gave the this gold colour during the plating process.(These regulations came out in 2003 as the "End of life vehicles2003"

Originally they were a drab grey/light silver colour.

Ensure the correct DOT4 or DOT5.1 brake fluid is used as these cylinders are not designed to use anything else such as Castrol SRF for racing or any mineral fluid.
