N3551R
During time that I owned this A/C, I had two occasions when the brakes locked on left gear. Fortunately, both times were during ground operation and no injuries or damage resulted. Actually required use of a screwdriver to move brake pads.
Thorough examination by mechanic and AI found nothing wrong on both occasions.
Brakes operated normally on subsequent flights. Other than these two exceptions, I was extremely pleased with the aircraft.
