cotter pins. Always follow recommendations
in this manual-replace these fasteners with
new parts where indicated, and any other
time it is deemed necessary by inspection.
To siphon brake fluid, always use a bleeder
bottle which is only used to siphon brake
fluid.
Brake fluid is poisonous and must NEVER be
removed by siphoning with your mouth.
