Early 2 litre disc brake conversion

[Stefan]

I did this years ago with a complete 406 front end.

Pretty straightforward, but it can be difficult to bleed the brakes, and I think that’s because my servo is on the left side of the car under the Bonnet with a long pipe run to the master culinder. My 403 had a factory fitted servo+ discs, and that was in a pod on the right side under the Bonnet. It also had a vacuum tank, not needed nowadays. I had SLJ fit a reduction valve to stop the rear brakes over braking.
After years of ownership I found my 403 had different sized rear cylinders. Could explain a 180* spin on heavy braking during a high speed run early one morning.
