The brushes are v. cheap parts, should have been replaced at the time the pcb was repaired.Theyre graphite blocks which transfer mains power to the copper segments of the motor -Theyre probably worn down. Power off, drag machine out onto the floor, remove the back cover and locate the motor. May help if the machine is tilted at an angle or laid on its side. The brushes are at the other end of the motor from the drive pulley. The holders are plastic or bakelite and are generally held in with screws or plastic clips. Also, look at the copper segments they run on to check for burning or pitting. If the segments are burnt or damaged you need a replacement motor or a replacement armature (motor part) if you can source one. I hope they havent caused another fault in the motor drive circuit board
