cotter pins
Anything special I need to know about cotter pins used in brakes other than that they are made of steel. I know bolts have grades. I am assuming that there is not since all the online parts places do not seem to sell them. I am to the brake reassembly stage and I don't want this to be the failure point.
Thanks for any help,
John

Since no one has replied, I'll jump in. I've been doing brakes for 25 years, and
have never seen cotter pins graded. I buy them at the local Napa in a box that has all
different sizes. As far as I know, they're all the same.
Hope that helps.

I have quite a few farm implements, and anybody will tell you that I can be rough on stuff. Some say that I could tear up an anvil. In the approximate 13 years I've been fooling with this stuff, I've never once broken a cotter pin. I've broken my fair share of big "main" pins, pto shafts, etc., but I've never broken a cotter pin. Tractor Supply sells a nice box which contains about a zillion different sizes of those things.

My local True Value has cotter pins in their bolt section that cost more and are made in SAE sizes, appear to be better quality. The Chinese ones are nearly always really metric and fit sloppy.
Where are cotter pins used on brakes? May be a Big Truck thing?

The main concern for safety is that the cotter pin fits and fills the hole. Use the largest diameter pin that goes into the hole, you don't want one where it rattles around. AFAIK all cotter pins are made from mild steel so they can be bent open easily without cracking.

and don't put them in backwards.... you'll never get them back out 
afa quality... the ones I buy at NAPA or good auto parts stores have a little more resistance bending than the ones I've had from H.F. must be that cheep Chinese metric steel... made from melted down girders from the buildings that Godzilla torched... totally took the temper out of the metal.
