On the taxi out at Freidrichshaffen I noticed a slight judder from the right hand brake. Back in the UK we replaced the pads and flipped the disc and all was well. G-EJBI flew three local flights in September, two local flights in October and just the one flight in November. December we flew a local flight and then commenced the annual maintenance. Little did I know it would be May 2021 before G-EJBI flew again.
