the old style maggie levers always brake on the tpa. but this can be fixed all you need is a bolt from a skateboard or one with the same thread it has to be between 1" and 1.5" now to start remove the lever blade look inside the blade where the broken bolt from the tpa is and remove it, then take the red part of the tpa off. there should be a square brass coloured bit, screw the new (skateboard) bolt into this holding the square bit with a pair of pliers then reassemble the lever. all fixed now to adjust the new tpa just hold the brass square and screw in the bolt or vice versa this should work perfect at least it did for me good luck and get riding.
