Q1: Thanks to this picture, Is it correct to understand that I should drill a new hole ? Because it really feels anti-mechanic to force.... Q2: I already tried with a washers for hydraulic braking tubing, and the result is that there is a little "play", the braking tube can even turn. I asked a friend, and he told me that on a normal PX there is no washer for this on the master-cylinder side... any other experience ?
