This Brake Thingy.......
OK, I recently bought an 86 Trek 500 Tri Series and I need to replace the brake pads, which are original, and in looking at the pads I am wondering what exactly this piece is called & what its intended purpose is? (See picture attached)
Just me being curious, thanks

I believe it's purpose is to guide the tires into place when you reinstall the front tire.

+1 / tire guides seems to be a common name for them.
I like to think they help cool the brake pads on long curvy downhill descents

Thanks! I thought it might have something to do with setting the brakes when doing adjustments

I don't think they were ever meant to cool the pads in any way, they are just for guiding the wheel to go between the pads/caliper arms for faster wheel changes. They also double as a handy way to pinch the calipers together when doing adjustments to the brake cable system.
Modolo used wires for guides on their brake pad holders, Many brake manufacturers later started to mould these guides in with their plastic pad holder as seen on Diacompe brakes of the mid - later 80's and even today on many brakesets. They are just not as visible as these older ones.

When determined that bikes were too light in weight, they added these widgets (and their attendant few grams of weight) to get the bikes up to official weight to prevent over-speeding by the riders.

Great, now I feel really old. These were signs that you had a really good bike with really good brakes....

Scott made brake pads with finned aluminum on the holder for heat dissapation. Not sure they were really needed but they do look cool. Most brake systems work best once they are heated up rather than cold.

I read somewhere that the fins did not really help, but they did look cool!
I guess the heat that happens on bike brake pads is localized to just to right where the rubber hits the rim and not much further back into the pad.

I used to do this too. Until one broke off! So I am careful not to use these to squeeze the brakes closed any more. A vintage Campy brake holder is costing more than $10 each these days.

Oh. Good tip BD63. Thanks. That hadn't occurred to me but you're right. Those things are getting very difficult to find and expensive! OK. No more of that practice. Thx.
