They always told us it was because the hydraulic fluid is warm to hot after using the brakes, at least in the calipers, and as it cools and the fluid contracts, brake pressure is reduced. That's why you sometimes see airplanes parked on a slight incline with the brakes locked rolling into things like other airplanes, hanger doors, and even fuel pumps. If I am walking away from the airplane, I always use chocks, whether that's with an airliner, a Cessna, or (I hope one day) my KR.

Hmmmm, I wonder why? _______________________________________ Search the KRnet Archives at http://tugantek.com/archmailv2-kr/search.
