Its a Girling cylinder that seems to be the most common one fitted to the Sierra range. It also seems to also be the one that is favoured by the Locust builders and various other "Seven" lookalikes.

It has three outlets - two at the furthest away from the servo for the fronts and the one closest to the servo for the rears. At 22mm diameter it is fairly close to the BMW 20.6mm diameter. Outlets are 10mm x 1mm which I think is the same as the BMW. Two face towards the engine and one downwards.

Biggest pain for me is that I have only one line going to the front at the moment and so will have to do rather more re-plumbing than I anticipated.

Robin,
great website! I had not found that one.....

BMC 4052 looks like Jason's M/C complete with the 'cut out'. It's also Ford/Bendix confirmed by Mike's contact and pictures.

I think the equivalent First Line part is FBM4068 which i'll check out at my local motor factors. These are also available on eBay but i would caution anyone ordering one at their own risk because I may not be right.
These are 22.2mm diameter pistons.

The older MK 4 Cortina MC's have a 20.6mm diameter, which is another option. (Less effort, but more travel for the same displaced fluid )

...peter

P.S. you can access the Firstline 'webcat' by using account number 16256 and password 'password'

PLEASE READ POST #525 below before ordering this M/C. THIS PART NUMBER MAY ONLY BE SUITABLE FOR CARS WITH DRUMS AT THE BACK
