Analysis

According to the pilot, during landing roll he applied brakes to maintain directional control. He heard a loud noise and experienced right brake failure. The acft veered left and came to rest in trees at the rnwy edge. Exam of the acft revealed the brake cable was stretched and had numerous broken strands at the woven cable splice. The brake linings were worn into the attaching rivet heads. The acft had reportedly just been thru an annual inspection less than one month earlier.
