The six studs that hold the brake and shaft in place are a problem. Some how
British ingenuity has failed here. I found that when reassembling the
trailer arm that all the studs were stripped and would not hold the mild
torque needed on them. Apparently the use of fine thread into the cast
aluminum was overlooked and this is where a few dollars must be spent. The
use of a 5/16 course thread Heli-coil is the answer here. Follow the
directions using a drill press please so that the old threads are drilled
out straight, not at an angle. Take your time when tapping new threads with
the tool provided in the kit. Then insert the coils and finish up with
inserting course thread studs with fine thread end extruding. A proper stud
puller is recommended, but the use of two correct nuts up against each other
in absence of the correct tool can be used. Just remember not to over
tighten them.
