Thanks Alan. When I bled the brakes I followed the manual exactly, in the order specified. I'll have to have another look, because from what you and Brock have said it seems that I may still have got it wrong. No big deal to go through the bled process again though, I'll have a look tomorrow or at least in the next few days. The brakes still are working fine, just the pedal movement is a bit disconcerting.
