Area washers are installed at each rod end to ensure they cannot escape in the event of a bearing collapse. 

Modification
Custom bolts were manufactured from M6 X 45 Unbrako screws. All bolt's where hand threaded to provide the required amount of plain shaft to suit each application and were to replaced all fully threaded bolts used in the pedal assembly's. Threads were trimmed to there correct length and polished using a plastic buff on a bench grinder to remove all sharp edges. 

Nylon or fiber washers install at brake pedal pivot's to adjust clearances to a minimum. 

All bolts were treated with Loctite 222 on assembly and nylock nuts installed as applicable.
