As part of my rebuild I completely replaced the brake system:
calipers and rear pressure valve rebuilt by PMB new ATE 19mm master cylinder new hard and flex lines new disks and Porterfield R4-S pads I went through many (many!) episodes of bleeding, with different methods. The pedal feels very firm from the first push, and does not pump up. Rear clearance is set at .004". I went through the PMB bedding process, and have driven around a bit. But the braking force seems weak. When I get on the brake pedal, I do not feel any "bite". Another 914 friend drove the car and also agrees. Any suggestions? |

I very recently got around to installing the KFP 1935's I got from CFR a long time ago, along with new rotors, etc. and like other haven't quite gotten the bite and feel I was hoping for, but also haven't gotten them smoking hot as Chris suggests yet.
I do notice they are getting better, but my question is how to visually tell if I have a 17mm or a 19mm MC? |

I do notice they are getting better, but my question is how to visually tell if I have a 17mm or a 19mm MC? My OE MC has a "17" cast into the housing on the bottom side between the mounting flange and rubber boot for the pedal rod. I'm assuming that designates the bore diameter. Unfortunately, you can't see it without pulling the MC out, or maybe with a mirror from the cockpit side after removing the pedal board? |
