What is this mysterious part called?

Is this piece (the little orange, broken one) called something specific? I'd like to see if I can replace it but have no idea what to search for? "Little orange brake lever part" has not yielded satisfactory results.

Thanks!!

Broken pivot pin for a brake lever with safety levers? You may just want to get a new brake, complete.

Hmmmm. I don't know. That is the "safety lever" that allows one to brake while riding the top of the bar. It's a pivot point. Ok. How about we call it
BRAKE SAFETY LEVER PIVOT AXLE?

It's broken, the chances of buying a new brake lever pivot shaft for an ancient Dia-Compe lever are zero. Find a similar used lever to cannibalise. They were common in the day. Try your local bike kitchen/ co-operative/ tip shop.

Pivot pins did not come only in orange. Red was most commonly seen, but also in blue and green rarely. Co-op suggestion was the best idea for finding one, or you might have to buy an old bike at a yard sale to get the one part. Good luck!

I have two or three sets of turkey lever brakes, diacomp, with the red dot. Can you PM yet? They're yours for the postage if you want.

Your bike appears to be a 1974 or later Schwinn in Lime/Emerald green. Schwinn, Dia-Compe and Weinmann called that part a "stud for pull up bolt", however they were also sometimes called pivot pins or even "dots":



The specific part you need would be this one: Vintage NOS Bicycle Brake Lever Extension Anodized Stud in Gold | eBay



Note that for mid-1973 and earlier models a different non-machined design was used, which would *not* be correct for your '74 or later bike: Vintage NOS Bicycle Brake Lever Anodized Stud in Gold | eBay



Also note that while other manufacturers used different colors for these studs/pins/dots, Schwinn specifically used orange/gold anodizing on these on its 1969 and later models (before that they were red).

You underestimate the boxes of things I have.

Thanks all for the helpful replies! Based on the serial number, it looks like the frame was made in November of 1979. However I have read that often the bike is assembled and sold several months later so maybe it's a 1980.

It looks like I need 10 posts to use the private messenger, so I apologize for another throw-away post after this.

I also can send you one in GOLD (or orange if you like), LMK, entire lever or just the pivot pin just cover my postage which should be pretty low cost.

Post the small 4-digit number stamped in the headbadge, that will indicate the day the bike was assembled.

Why are the chances zero?
Dia Compe sells new brake levers for $40.

Looks like the number is 0370?

Thanks to everyone for the help and generosity! I am happy to say that the brakes are both fully operational!

That would indicate a bike assembled on Wed. February 6th, 1980.

I, too, have a stash of similar parts.

If you do not care about the extension ("safety") levers or about keeping the bike original, this would be a good opportunity to consider upgrading to modern aero brake handles, which improve your braking leverage by about 10-15 percent. Otherwise, stick with the good ol' Weinmann handles when you find a replacement pivot or whole assembly (pretty easy either way), but make sure to replace your brake pads with KoolStop salmons.
