I recently had to bleed brakes on a FIAT, and I wanted to check some details on the Fiat Forum - where I found very strong advice against using the old 'pedal push' method. The danger is that you are likely to be pressing the seals further down the bore of the master cylinder than they would usually go. A small amount of water (from condensation) often collects in this area and as this part of the bore is not regularly swept clean by the passing seal it can lead to rusting of the internal bore, and - as the seal passes over the rusted area during long pedal push bleeding - the seal gets damaged. I can confirm that this is exactly what happened to me twice whilst trying to re-seal a MC
!Easy-Bleed device worked brilliantly on the Fiat, so I'm now modding an old cap for Morris use
