I made a post some time ago regarding upgrading the small (10.25 inch diameter) Girling front brakes to the Big front brakes (11.25 inch diameter). The information is in the 700/900 FAQ along with the information on the Jumbo brake upgrade.
Today I did a little parts fitting and found that you can install the Big brakes (11.25 inch diameter front rotors) on the early 700 series which are equipped with the small (10.25 inch diameter) rotors on the front. Assuming that you already have the separate hubs and rotors with your 10.25 inch diameter front Bendix brakes, all you need are the caliper holding brackets for Bendix (Girling calipers take Girling caliper holding brackets as noted in the 700/900 FAQ) and the larger (11.25 inch diameter rotors). I would encourage anyone with the small front brakes to upgrade to the Big brakes when doing a front brake job. It is quite easy and does not involve opening the hydraulic brake lines like the installation of the Jumbo brakes on my 1987 745T.
If you don't already have the separate hubs and rotors, the separate hubs can be purchased inexpensively from a wrecking yard.
