Upgraded brake master cylinder for two zones (front and rear) floor mounted pedals. This does not have a brake bias adjustment.

This is not a complete direct replacement for the Ford Sierra unit, The brake lines fittings will need to be changed from M10 x 1.0 to M10 x 1.25

The Bore on this master cylinder is 19.05, the standard Ford Sierra unit is 22.22

If you are upgrading from a standard Ford Sierra master cylinder, you will need the following component parts to make this work:

1 x M10 x 1 3 way Tee Joiner 1 x M10 x 1 (Male) to M10 x 1.25 (Male) - joined with a short piece of brake pipe. 1 x M10 x 1 (FeMale) to M10 x 1.25 (Male) joined with a short piece of brake pipe

Plumbing : The forward facing single outlet is for the front circuit, the rearward facing outlets are for the rear circuit.  You can blank off one of the rearward outlets as this is not required on a standard vehicle.
