With the prospect of incoming rotten tomatoes forefront, I wade in here looking for a little BTDT.
Background, just got the 74, 2.0 back on the road after a 7 year hiatus. Over the years,, I did fuel system, brake system (19mm master(ATE) /calipers (PMB rebuilt fronts, stock rears) /rotors/hoses) engine mechanicals and cosmetics. I haven't driven the car during that time and I only had about 150 miles on it before it came off the road and memory ain't what it used to be. I did the 19mm MC many years back because it was way less expensive than the 17 and the forum feedback seemed fine. I also have a mid 80's Carrera (with turbo brakes) against which many folks relate the 19mm MC pedal feel. I like a firm pedal and the 911 is pretty easily modulated, heavy but responsive. Fast forward to this past week and some short shakedown runs. The 914 pedal is "right there" and noticeably firmer than the 911. But while being firmer, the braking is far from commensurate with pedal input. Yes, the 911 pedal is firm, but with the right effort, the car will slow/stop NOW. Been on the track with it no problem. On the 'teener, I feel like I am about to bend/break the pedal and the car seems to barely slow. No way I can lock up these brakes at any road speed, nor do I feel I could lose momentum in a hurried stop situation, even at in town speeds. I'm wondering if I have missed something or is this type of pedal feel/action is "typical" of the swap? Shamefully, I honestly can't recall if I did pads, but the rotors are spotless and look like they're getting good pad contact but would love any pad advice as well. |

Some speculation:
If you have a firm/hard pedal that does not pump up at all, you probably have the system properly bled. If the pads are newish, you may still need to bed them. And there is a chance you glazed the pads by being too gentle to start. Ask me how I know. A zero cost process is to lightly sand the pads, reinstall, and then bed them again. And bed them HOT and HARD. You should smell brakes. Finally, like I mentioned above, make sure the MC is not moving with hard pedal pressure. I had to make a brace for mine. Like others have said, even with a 19mm MC, 914 brakes work. It took me a year (with a winter season off) to go from weak brakes to good brakes. |
