Thanks Walt. You make a good point about about the difference with boosted brakes, it's been a long time since I've driven anything otherwise. I used to have a 356 replica but the brake pedal wasn't near as hard as the one on the 912. It's been that way since I bought it in december (haven't driven it much since as it's been getting some rust repair done). The brakes do work well, so maybe it is just what you imply. I still plan on doing the caliper swap, rotors, and obvious bleeding that goes along, so we'll see what comes of that.
If I recall the mc on that was on my car was a single circuit but my friend ( a tech) did the install of the new and it was a dual circuit. Not sure why it's leaking. Possibly just from sitting for 6 months but I don't think thats a normal mc thing.
