Most of the time has been due to the bike shop in Morgins doing helpful things like cutting the (literally brand new) rear brake line rather than pulling it out of the frame, which then contaminated the (brand new) pads in the rear calliper, and then keeping my (brand new) MT7 lever and leaving a cheap Magura lever that they had in the workshop in my box of parts.
But, we did think we had the front bled up properly this morning, and a couple of hours later the lever went to the bar.
