I think newer hoses/neopreme may have solved the issue. Do NOT overlook master cylinder/pedal issues.

Draw a straight line from KIOW to T82 and it crosses right over the
Lake Texoma area, so Durant would be much closer stop. Ponca City would be further off the path. I'd still opt for Cedar Mills (3T0) on the Texas side myself, just for the scenery and experience of the approach to and takeoff from the lake-end of the runway. Cheap fuel (plus a courtesy car and good BBQ) is also available at Gainesville, TX (KGLE) just a few miles west of the lake, and also cheap fuel at Sherman (KSWI) just a few miles southeast of the lake. |

No no no...it's "Hail Mary", not "Blame Mary". :-)
Now Jack here is obviously a successfully married man... ;-) Well, the parts arrived from Spruce by 10 AM this morning, and the brakes were fixed by lunch. Atlas is tucked safely back in his hangar, fully fueled and ready to go. All we need now is some nice weather on Sunday. It's 35 degrees and raining, right now -- ain't nuthin' flying around Iowa City... Prog charts show a big chunk of (argh!) thunderstorms moving into Oklahoma and Texas on Sunday morning... :-( -- Jay Honeck Iowa City, IA Pathfinder N56993 www.AlexisParkInn.com "Your Aviation Destination" |

Ouch...
This is one of those stories that makes me glad that I didn't spend the extra money (and lost useful load) to install Toe-Brakes in 61J... Yes it was odd... for the first 5 minutes of taxiing. After seeing two of my old club's planes go through a set of pads per 100 hour inspection (one of them having a similar catastrophic right (I believe) break failure... only during a landing... only a VERY good instructor prevented a ground-loop). And then hear stories like this from a very experienced pilot no-less... I can't say I miss them. I have had a right break failure in a piper with toe brakes also right brake stuck upon applying them. This makes me just a little curious. Is the handbrake on a Piper (without toe brakes) mechanical or hydraulic? My reason for asking is that, if hydraulic, the same culd happen with the handbrake--although the possiblility of inadvertantly dragging the right brake while applying rudder would be eliminated.

And a few cars, such as Corvettes in the middle 1960s, were reputed to have springs inside the calipers so that the pads would not retract. This was supposed to keep the pads and disks cleaner and drier, with only a very slight increase in the rate of wear. I never owned one and don't know how well it worked.

Yep, low ceilings, crappy visibility, possibly rain and thundershowers from west of Wichita Falls all along the Red River all the way to Lake Texoma forecast for most of the day Sunday. MVFR at best, probably actually gonna be IMC though. Might be a better idea to try again Monday. Or if you can, leave Saturday morning. It's supposed to be very clear and almost no winds all day Saturday across the local region here. |

Yeah, we'll probably only make it half-way down Sunday anyway...so flying in to Fredericksburg on Monday is no biggie. Can't leave today, dang it. Got a million loose ends to tie before we can leave the hotel for a week... -- Jay Honeck Iowa City, IA Pathfinder N56993 www.AlexisParkInn.com "Your Aviation Destination" |

Yes its hydraulic (Single Cylinder)... so yes, it could definitely
still fail. The whole system is much simpler (And lighter, by about 8 lbs) than the toe-brake system though, and according to my mechanic at least, its basically bullet-proof... This is simply according to him - but apparently fried right wheels/ brakes are a reasonably common (especially on Grummans and training aircraft)... he attributes it simply to the subconscious dragging on takeoff/taxi... At the very least, the right pads wear faster than the left on most planes he looks at, even with experienced pilots. The only planes he doesn't see it on are the few that don't have toe brakes. That was enough for me... (Disclaimer, I am a young, low-time pilot with ABSOLUTELY no experience in this matter, other than I learned in a few toe-brake planes before I bought 61J, and I adapted to no toe-brakes in about 5 minutes...) I do tend to trust the opinion of a mechanic who tells me not to give him money for things though... -Scott |

I presume you're meaning on aircraft like the TriPacer which has the hand brake, but no toe brakes. In the TriPacer, a cable goes from the hand brake, around a few pulleys, and ultimately it ends up under the pilot's seat. Under the pilot's seat (and I'm not joking) you will find a Piper Cub heel brake, with a hole in the back of the heel brake, where the cable connects. The heel brake is hydraulic and applies both wheel brakes simultaneously. The diaphragm has a habit of splitting just when you really need the brakes, leaving you with nothing! -- Yes, the Reply-To email address is valid.
