A few years ago, I changed the brake master cylinder of my Ami 8, but I was not satisfied with the result; spongy, a bit indirect feel of the pedal when pressed. So I searched the internet and found a new old stock one that I fitted during the front area restauration. I have to bleed the brakes, but I hope the result will be good: a nice and firm brake pedal.
