My latest '75 model from Oregon came to me in parts, but mostly complete. I built a 2056 with Elgin cam and twin Weber 40 IDF's and am quite happy with the results. She has a decent kick and gets 30+ mpg cruising over 70 mph. One rear caliper was missing, but I had a newly rebuilt one and changed it out. I used my shop air with about 5 psi to bleed and it worked for the most part. My pedal is about 80% of where I would like it.
Q: where is the brake fluid going? I recently sold my 356SC that had the same issue, but it had a drip in the rear circuit. This time I cannot see leakage anywhere thanks |

There is a much much much better alternative for brake fluid: silicone brake fluid. Among other things, it's not hygroscopic. It has a higher boiling point. It won't harm your paint or promote rust.
It's best not to mix with "conventional" types of brake fluids as it can creates so called "worms" when the different fluids interact. One of my projects this winter is replacing the 914's front suspension and rear trailing arms with 911 stuff along with the MC, all brake lines, pressure regulator, etc. A perfect time to upgrade to silicone brake fluid. I've done the same upgrade to another vehicle of ours and it works as advertised. |
