I?m on a big cross county trip, visiting family in Summerside, PEI, 2400 NM from home. It?s been a good trip,, RVs are a great way to travel. I had 3 weather related diversions, but never got into much trouble. My first day last Saturday had me lose all of my brake fluid on the right side after landing. This was resolved after we found a broken flare in the top of leg fitting. Brakes worked great until yesterday. After a couple of short flights here I noticed my right brake was gone on rollout. After a half dozen left hand pirouettes for my right exit I had to shut down to stop turning. Got a tow back to the hangar and got a look today. I set out to bleed the brake and quickly discovered when my son pressed on the brake that fluid was coming out around the piston. No standing leak, but I had lost some fluid earlier at the end of the runway.
We removed the calliper and I got the piston out. There were no signs of any problems, not in the calliper, nor the piston or o-ring. Everything was nice and smooth. We?ll reinstall it tomorrow and check agin, just in case there was something contaminating the seal. I am not optimistic, I have always had problems with this brake leaking occasionally. I suspect there may be a non-visible defect in the assembly. Anyone else see this?
I?ve got Marco callipers, and less than 100 hours on them.
